Basics of Geo-Mechanics and Hydrology Part III - Basics of Hydromechanics

Introduction to HydrologyThe water on our earth is in a constantly changing

circulation system. The following figure 1 shows a simplified diagram of the water balance of the earth.

Eine notwendige Voraussetzung zur Planung von Bergwerken bildet die genaue Kenntnis über die physikalischen und mechanischen Eigenschaften des Untergrundes. Im ersten Abschnitt

im AMS-Online Heft 04/2010 wurden einige elementare Eigenschaften des Untergrundes, speziell für Lockergesteine vorgestellt. Im Anschluss daran wurden zu Beginn des Jahres im AMS-Online Heft 01/2011 auf die Kennwerte bezüglich Durchlässigkeit und Festigkeit des Lockergesteins eingegangen. Der Teil III widmet sich nun den hydromechanischen Grundlagen. Im Rahmen dieses Beitrages wird vorrangig auf die Bedeutung des Wassers eingegangen.

The basic equation of hydrology gives an overview over the water balance of the earth, and contains the main components of the water balance of the earth:

Table 1 gives an overview over the size and composition of water reservoirs of the earth. The lion’s share of the water resources lies in the oceans and is in form of salt water.

Characteristics of WaterAs generally known, water is found on earth in three

aggregate states, fluid, solid and gaseous. Chemically, water consists of two parts hydrogen and one part oxygen.

Water has several physical characteristics. As such, water reduces its density and expands when it freezes. All other material contracts during hardening in case of a reduction of temperature and as such becomes denser than its fluid. This is the reason that hardened iron sinks in its melt, whereas ice floats on water.

The specific characteristics of water are mainly based on the molecular structure of the H2O water molecule.

The oxygen atom displays strong electronegative characteristics, which is due to its six outer electrons and the fact that atoms strive for a full outer shell with eight electrons. The strongly electronegative oxygen atom attracts the hydrogen electrons. Therefore an unequal charge distribution and a polar molecule come into existence. This is called a dipole. Figure 3 shows the generation of such a dipolar water molecule. Due to the lack of electrons the hydrogen atoms have a partially positive, and the oxygen molecule has a partially negative charge. Water molecules develop hydrogen bridges among each other. This occurs because of electrostatic forces between partially positively charged hydrogen atoms and the partially negatively charged oxygen atom and leads to a tetrahedron arrangement.

The specific physical and chemical characteristics of water are based on the mentioned dipole character of the water molecules. The following figure 4 shows a general phase diagram, which can be applied to most substances.

The melting curve, which is tilted to the right, shows a characteristic course. At constant temperature (marked by the red line in the diagram), and with increase of pressure, a fluid turns to a solid. In this connection water shows an anomaly, as the melting curve tilts to the left (figure 5).

EDUCATION

At a constant temperature (marked as red line in the diagram), an increase in pressure leads to a reduction of the freezing point. It is only because of this phenomenon, that it is possible to skate on ice. The high pressure incurring from the weight of the skater liquefies the ice. This water film makes gliding possible. As an example it would not be possible to ice skate on CO2-ice (dry ice). The reason for these characteristics of water is also due to the formation of hydrogen bonds.

The unusual cohesion of water (high surface tension) is also related to the formation of hydrogen bonds. The capillarity, i.e. ascension of water in narrow tubes, is related to the surface tension. In full wetting, the capillary head h of water in a capillary tube is calculated according to the following formula:

gRh ⋅⋅⋅=ρσ2 Term 2

withσ: capillarity [N/cm]ρ: density [g/cm³]R: capillary radius [cm]g: gravitational acceleration [m/s²]

The thermal conductivity of water is very low, and a high energy input is needed to warm water. 2,257 kJ are required for vaporization of 1 kg of water. This heat is again released during condensation of water (heat of condensation).

Water is a very good heat store, i.e. it releases its heat energy very slowly. This explains the differences in temperature fluctuations between a balanced oceanic

climate and a continental climate, which is characterized by major temperature fluctuations. Furthermore, this characteristic in the reason for the see-land-wind system of the earth.

Water in SoilUnder normal conditions all soil contains water. The pores of soil are very often filled with water, while solid rocks mainly contain water in clefts. In case water cannot be removed from an earth sample, even after a drying of 105 °C, it is not categorized as ground water, but as crystal water of soil particles. Figure 6 shows a rough overview over the division of the earth zones into percolation zone, capillary zone and ground water zone.

Water can occur in various manifestations in soil. According to DIN 4049, ground water is defined as “underground water, which cohesively fills the cavities of the earth crust, and the movements of which are solely determined by gravity and the friction forces caused by the movements itself“ [14].

The ground water horizon can develop a free ground water level or a potentiometric surface. A so-called potentiometric surface can appear in a ground water body, which has been developed in an aquifer and is covered by an aquiclude, and the course of the groundwater level can be described by so-called hydrographs. In soil aquifers, the fluctuations of the ground water level are very low, whereas they can be high in fractured and karst aquifers. The following figure 7 shows an example of a ground water hydrograph during the time frame of 1978 until September 1987.

Fig. 5:Phase diagram of water


EDUCATION

In case water is only present for part of the year, e.g. during spring, it is called percolating water. Ground water or percolating water layers are usually developed above a layer with low permeability, a so-called aquiclude. Ground water is generated in relatively permeable soil or fissured rocks (aquifer) through the accumulation of percolating water.

Water on partially impermeable layers, that is limited in amount and location, is called strata water.

Part of the water in soil is present as adsorption water. Adsorption describes the tendency of fluid components to accumulate on solid surface. In this case the adsorption forces occur between the solid phase soil matrix and the water molecules.

The so-called capillary water is kept in the capillaries of earth by adhesion and cohesion forces. Herby the capillary water rises the higher, the smaller the pore diameter of the soil is. Figure 8 shows the occurrence of adsorption and capillary water.

Fig. 6:Division of earth zones

Fig. 7:Ground water hydrograph [22]


EDUCATION

Part of the ground water, which is kept in the soil pores, against gravity, is called attached ground water. Attached ground water can occur either as adsorption water at the surface of solid soil particles, or as capillary water in soil pores, and is a generic term for adsorption and capillary water. In sand, the portion of attached ground water can be up to 10%, in silt up to 35% and in clay even up to 45%.

Figure 9 shows the course of the gravity attractive forces between grain surface and water molecules, subject to distance.Freewateroccursfromadistanceof5•10-5 mm upwards. In this case the attraction forces are very low, and the water is mobile. In case of smaller distances to

the grain surface, the occurring forces rise exponentially. Due to molecular forces, bound and absorbed pore water can usually not be mobilized through hydrodynamic forces. Only free pore water can flow.

Figure 10 again gives an overview over the distribution and movement of ground water.

EDUCATION

Another important term in hydrogeology is the multi-aquifer formulation (groundwater storey). Groundwater storeys consist of the alternation between aquifers and rock bodies. Aquifers absorb and transfer ground water and ground water can circulate in them. Aquifers have a high permeability. Based on the consistence of rocks, pore – fractured and karst aquifers can be differentiated. Aquicludes are layers with a low permeability that retain percolating water. A major criterion of aquicludes is the fact, that the water flowing from above flows off quicker to the side than downwards.

The following figure 11 shows an example for the arrangement of aquifers and aquicludes.

The aquifers that can be found in nature can be divided into various types. One important aspect is the differentiation between confined and unconfined aquifers.

Unconfined aquifers are characterized by a free (unconfined) ground water surface, where air and water pressure are in balance. In such an aquifer, the stand pipe water level in a well corresponds to the water level in the aquifer. In case water is extracted from a borehole in free ground water, and if there is no regeneration of ground water, the aquifer will be emptied. It creates a relatively steep fall of the ground water level (Absenktrichter).

An aquifer that lies between two aquicludes, is called a confined aquifer (artesian aquifer). In a confined aquifer this lies in a well above the upper aquiclude. In such an artesian aquifer the stand pipe level even lies above the earth surface, and the water leaves the well (artesian well, figure 13 and 14).

Fig. 11:Groundwater storey [18]

Fig. 12:Demonstration of a ABSENKTRICHTER


EDUCATION

An artesian well is a well that only flows through the pressure of ground water. Natural artesian wells can often be found in oases in deserts. Artesian wells always lie below their immediate surroundings. If the water-bearing stratum shows a trough structure and the stratum is drilled, the water is pressed to the surface by itself through the existing pressure in the confined aquifer. According to the principle of communicating pipes, the water from the confined layer can maximally rise up to the highest point of the ground water level in the water-bearing stratum.

The pressure of an artesian well decreases, in case the afflux is lower than the extracted water amount, i.e. if the ground water level in the water-bearing layer sinks, due to the water extraction.

The phenomenon of confined ground water is of high importance for construction and mining measures, since the movement of earth masses and the resulting changes in load can lead to floor and shear failures in mountains.

In case an upward ground water flow completely cuts the shear strength, a hydraulic shear failure occurs. In this case, the flow force affecting the grains exceeds the weight of the soil grains under uplift pressure and the soil skeleton looses its cohesion.

Aquifers can further be classified according to their strength and the type of flow-through cavities. Hereby the following distinction can be made:

Pore aquifers,•

Fractured aquiferes and•

Karst aquifers.•

Pore aquifers are mainly found in soil. The pores, which have a portion of approximately 30%, are filled with water.

The flow-through cavity, through which the ground water can move, is composed of these pores. Fractured aquifers can be found in hard rocks. Cleft ground water is groundwater in hard rocks, in which cavities are due to clefts and other slits. Karst aquifers are developed in karstified rocks. One example for karst ground water aquifers are karst cavities in carbonated rocks. These cavities are generated by the mostly different chemical composition of carbonated rocks and the accompanying uneven solvent power of the water containing CO2. Therefore irregular cavities, which can be flown through by ground water, are generated over geological timeframes. In karst regions, there is a close connection between ground and surface water and very high fluctuations of ground water levels can occur. Figure 15 graphically depicts the three mentioned types of aquifers.

The following figure 16 shows the occurrence of various types of aquifers, at the example of the federal state North Rhine Westphalia.

WISMUT – URANIUM ORE MINING and remediation of legacies in Saxony and Thuringia

History of Uranium and of the Wismut company

In an address delivered in 1789 to the Prussian Academy of Sciences in Berlin, the German chemist Martin Heinrich Klaproth announced the discovery of Uranium. Henri Becquerel was the first to uncover its radioactive properties in 1896. Two years later, Marie Curie (a student of Becquerel’s) coined the term „radioactivity“ (from Latin radiare = emit beams) after having discovered that thorium-bearing compounds emit the same type of radiation.

Wismut GmbH was founded 20 years ago with the mission of decommissioning former uranium mining and processing facilities in Saxony and Thuringia and rehabilitating and

reclaiming contaminated plant areas. This study is intended to outline the corporate history of Wismut and progress achieved thus far in implementing the rehabilitation project.

by Ulrich Rieger, BMWi | Germany

Dr.-Ing. Stefan Mann, Reinhard RichterWismut GmbH | Germany

During the 19th century and until the mid-20th century, uranium was used for tinting glass and ceramics. Uranium compounds were used in glass-making to tint vases and decorative objects, but also articles of daily use such as bowls, glasses etc., in a yellow-greenish colour (Anna green).

After the dropping of American atomic bombs on Hiroshima and Nagasaki and the end of World War II the nuclear arms race began. As the Soviet nuclear industry had no domestic raw material supply, the Soviet occupying power undertook intense prospecting for uranium ore. In September 1945 the „Sächsische Erkundungsexpedition

Fig. 1:Wismut sites

22Issue 02 | 2011



(Saxony ore search department)“ was established under the overall control of the Soviet military. Its task was the search for uranium deposits in the Ore Mountains in Saxony. As mining operations by the Wismut company proceeded, prospecting and exploration were extended up to the Harz Mountains and towards Western Thuringia as well as to Eastern Saxony.

Order No. 131 of the SMA (Soviet Military Administration) in Saxony transferred German mining companies into Soviet ownership (Johanngeorgenstadt, Schneeberg, Oberschlema, Annaberg, Lauter, and Marienberg as well as the Pechtelsgrün processing facility) „to partially settle reparation claims of the USSR“.

Established in 1947 as state-run nonferrous metal company (AG) Wismut, the company changed to bi-national Soviet-German ownership (SDAG) Wismut in 1954 and continued uranium ore mining and processing in Saxony and Thuringia until the end of 1990. In the early 1950s, Wismut occasionally had up to 130,000 employees on its payroll. By the end of uranium ore mining at the end of 1990, AG/SDAG Wismut had produced a total of 231,000 tonnes of uranium, ranking the GDR as the world‘s fourth largest uranium producer after the USSR, the United States, and Canada.

With German reunification the Federal Republic of Germany assumed responsibility for the Wismut company. In October 1990, the Federal Republic of Germany and the USSR signed a transition agreement under the provisions of which SDAG Wismut ceased its operations on

January 1, 1991. This put an end to uranium ore mining by Wismut. The Federal Republic of Germany and the USSR signed a governmental agreement on May 16, 1991, on the termination of Wismut operations. With the coming into force of the „Wismut Act“ in December 1991, the company SDAG Wismut was changed into Wismut GmbH, a company under German corporate law.

Corporate restructuring was initiated as long ago as 1990 with the establishment of Wismut I, Mining Division (subsequently became Wismut GmbH) and Wismut II, Mechanical and Structural Steelwork Engineering, Civil Engineering, Logistics, Service, and Consulting/Engineering Divisions and completed in 1992 by the splitting off of the later mentioned divisions which were to operate under the company name „DFA Fertigungs- und Anlagenbaugesellschaft“.

Uranium mining legacies left behind in Saxony and Thuringia

Beginning already in 1986, ecological activists in the GDR undertook research on the sanitary and ecological consequences of uranium mining by Wismut. In 1988, the Kirchliche Forschungsheim Wittenberg published the documentary study „Pechblende“ - Der Uranbergbau in der DDR und seine Folgen“ (Pitchblende – Uranium mining in the GDR and its consequences) by Michael Beleites. What had been a subject that was untouchable for many was for the first time unveiled to a wider public.

At the time when uranium production was terminated, Wismut plant areas covered a total area of ca. 37 km2; this total included the areas of 7 mining sites (example – figure 2) and 2 processing units, ca. 311 million m³ of radioactive waste rock (mine dumps, example – figure 3) dumped on 1,517 ha as well as some 160 million m³ of tailings (residues of chemical processing). These legacies are located within densely populated areas of the Free States of Saxony and Thuringia.

Extending right to the outskirts of the town of Ronneburg was a worked-out open pit mine with a residual depth of 150 m, a length of 2 km and a width of 1 km, and with a residual open volume of 84 million m³ (figures 4, 5).

Uranium mining legacies were particularly severe at Schlema, the former radium spa which had to close its facilities already in November 1946 on Soviet orders. At this site, 40 waste rock piles containing ca. 45 million m³ had been dumped in some cases in the immediate vicinity of inhabited areas. With its height of some 41 metres, waste rock pile #250 was visible from far away and shaped the local landscape for many years (figure 6). Buildings and infrastructure of the radium spa had for the most part to be

demolished because uranium mining near ground surface had caused surface subsidence of up to 6 m. What became known as subsidence area extended over a surface of ca. 15 ha (figure 7).

While residues of uranium ore mining were dumped on waste rock piles, the residues of uranium ore processing (tailings) were deposited in tailings management areas (TMA) (figure 8). These TMAs were for the most part established in gravel pits, in worked out open pit uranium mines, or by the damming of valley locations (figure 9). At the two processing sites of Crossen and Seelingstädt a total of some 160 million m³ of tailings were deposited in the TMA by 1990. Thickness of the tailings in the TMA varies from 10 to 72 m.

In addition to the legacies left behind on the surface at the time when uranium mining was terminated, the mining sites in Saxony and Thuringia also included 56 pit shafts and 1,400 km of open underground mine workings with a maximum depth of up to 1,800 m.

Bases of rehabilitation and financingThe „Wismut Act“ assigns the societal task to Wismut

GmbH to rehabilitate the legacies left behind by uranium mining and milling operations. The legal framework for the project is set forth in a number of laws and regulations the most prominent of which are the Federal Mining Act, the Atomic Energy Act, the Radiation Protection Ordinance, and the Federal Water Act. Furthermore, under the provisions of the German unification treaty, two former GDR regulations continue to be applied:

Ordinance on the Guarantee of Nuclear Safety and Radia-•tion Protection (VOAS) of October 11,1984, including VOAS implementing regulation,

Directive on Guarantee of Radiation Protection for Waste •Rock Piles and Tailings Ponds and the Usage of Materials Deposited Therein (HaldAO) of November 17, 1980.

Furthermore, the assessment of impacts due to the mining and milling of uranium ores also considered relevant recommendations issued by the Commission on Radiological Protection (SSK). The paramount criterion underlying the radiological evaluation and selection of remedial options was the observance of a guidance value for additional exposure due to uranium mining of 1 mSv/a. This effective equivalent dose is the sum of all components impacting the reference person at the considered reference site.

In addition to the legal framework for the conduct of the remedial operations, the creation of the financial conditions was another crucial prerequisite. With the aforementioned agreement between the Federal Republic of Germany and the Soviet Union of May 16, 1991, the federal government has also assumed the sole financial responsibility for the company Wismut GmbH. Based on a rehabilitation program, the federal government assumed a financial commitment to fund the environmental restoration project. A recent assessment of the rehabilitation programme puts cleanup costs at some 7,1 billion euros for a period running up to 2040. During 20 years of remediation activities some 5.4 billion euros have been spent.

In 1991, SDAG Wismut had 27,800 employees on its payroll. In 1992, the newly established Wismut GmbH had ca. 6,700 employees (on January 1, 2010: ca. 1,500). More than 10,000 former employees had registered with job creation schemes and employee development and vocational training programmes in Western Saxony and Eastern Thuringia, and ca. 9,600 had found jobs in the newly established DFA which was spun off in 1992.

FOCUS OF REMEDIAL ACTION

Mine decommissioning, remediation, and flooding

In mine decommissioning, the initial cleanup measure was the removal of all substances with the potential to contaminate the incoming water. A special case of mine flooding is the Königstein mine where uranium mining had switched later to in situ leaching with dilute sulphuric acid. The mobilised contaminant potential has to be neutralised within reasonable technical and spending limits by a targeted decommissioning process involving washing and post-treatment.

Partial backfilling of mine cavities and mine flooding helps prevent surface subsidence damages. In the long term protection of groundwater against further releases of contaminants, and of heavy metals is achieved particular. Figure 11 depicts the schematic evolution of mine flooding at the Schlema- Alberoda site.

Area rehabilitation - dismantling - demolition

Contaminated materials generated as part of area cleanup or of dismantling and demolishing operations are selectively sorted and separately disposed of. Uncontaminated materials are being recycled. Excavated soil contaminated with radionuclides and hydrocarbons is treated in microbiological units before it is eligible for disposal in engineered cells (e.g. within tailings management areas or waste rock piles). These cells are subsequently sealed and vegetated.

Figures 12/13 exemplify the rehabilitation of a former plant area. Until now, a total surface area of 1,337 ha was reclaimed involving the excavation and placement of ca. 19 million m³ of material. To date, more than 700 ha of the reclaimed areas have been sold, primarily for agricultural and forestry reuse.

Rehabilitation of waste rock piles and open pit mine

Following comprehensive radiological, geotechnical, and geochemical evaluation of the waste rock materials the appropriate planning and licensing documents were developed. When regulatory approval was received work was initiated to profile waste rock piles with a view to achieving enduring stability.

27Issue 02 | 2011



As exemplified by waste rock pile #366 (figures 14/15), Aue Operations Office, remediation progress is clearly visible at all other sites as well. Regrading of waste rock pile #366 was a prerequisite for running the feeder road from Aue to the BAB 72 motorway across that waste rock pile.

Uranium ore was not only mined in underground pits but to some extent also in open pit mines. The last and largest open pit mine of Wismut awaiting backfilling was located near the town of Ronneburg (figure 16). Its depth which

once had been at a maximum of 240 m was still ca. 150 m in 1990. By 1991, 76 million m³ of waste rock material had already been relocated into the open pit for backfilling. Starting in 1991, the residual hole of the Lichtenberg open pit was backfilled with material excavated from surrounding waste rock piles according to an approved pattern.

In addition to waste rock, radioactively contaminated materials generated as part of the cleanup during demolition and area rehabilitation (demolition debris, scrap, excavated soil) was also placed into the open pit.

To date, a total of ca. 132 million m³ of mine waste were placed into the open pit mine as part of the cleanup process. The mound created on top of the backfilled open pit was capped and vegetated (figure 17). A road and trail network and a system of surface water drains are being implemented. Works are slated for completion in 2014/2015. The observation point known as „Schmirchau height“ was made accessible to the public already in July 2010.

Remediation of tailings management areas

Since 1991, remediation of tailings management areas (TMA) poses a formidable challenge.

After having examined a number of options, Wismut has identified in situ reclamation of the facilities including partial dewatering of the residues by technical means as the preferred option. Following removal and treatment of the supernatant water, this option involves the placement of an interim cover and of a final cover to be implemented at a later stage (figures 18/19).

29Issue 02 | 2011



The various work steps for placing the interim cover include (figure 20):

Placement of geofabric to protect exposed tailings against •dusting and of geogrid to enhance the load-bearing capacity and improve load distribution,

Establishment of vertical and horizontal drains to enhance •the consolidation process and expel pore waters, as well as

Placement of a mineral cover layer to serve as a working •platform and surcharge load to enhance consolidation

Placement of the final cover serves the dual purpose of long-term reduction of contaminant release and of providing the basis for subsequent landscaping. The cover consists of mineral soil materials and is designed according to the storage and evaporation principle with a thickness 1.5 m to 2.0 m. Quality assurance programmes are defined for all remedial operations.

Such waters include:

Flood water, rising groundwater in mines subject to flooding •and overflow water when mines are flooded,

Supernatant and pore water, the water contained in the •tailings management areas of former uranium processing units,

Surface water/seepage, water infiltrated into waste rock •piles and tailings management areas, respectively, and emerging at the toe of the dump or of the dam.

The total volume of waters requiring treatment at all sites is assumed to amount to ca. 750 million m³ during the entire rehabilitation period. The water treatment units are being adapted to declining feed water volumes and contaminant loads. Such decline, and eventual compliance, will also determine how long the treatment units will have to be operated. Current estimates, on a site by site basis, are in the order of 25 to 30 years.

Environmental monitoringRemedial measures are subject to emission and

immission surveillance under approved basic programmes to monitor environmental radioactivity.

Wismut GmbH operates a rehabilitation monitoring and a basic monitoring system in order to ensure:

surveillance of water, atmospheric, •and soil pathways as well as of the biosphere,

documentation of the impact on •humans and the environment during and after remedial work,

demonstration of regulatory compli-•ance, and

performance review.•

In 2010, Wismut operated a total of 2,070 measuring points. Of that total, 600 monitored the atmospheric pathway, 370 monitored surface water, and 1,100 monitored groundwater. Under the 2010 water pathway monitoring programme, ca. 10,000 samples were taken and analysed. An additional 25,000 samples were analysed for purposes of control and surveillance of Wismut‘s water treatment plants. Figure 21 portrays the current State of remediation progress achieved by Wismut GmbH.

Formerly abandoned Wismut sitesThese legacies were assessed to determine their

radiological impacts under the inventory program on behalf of the Federal Office of Radiation Protection. In Saxony, more than 1,900 of such objects (waste rock piles, pit shafts, tailings management areas - figures 22/23) were identified. Other formerly abandoned sites are located in Thuringia and Saxony-Anhalt.

With a view to remediating these formerly abandoned Wismut sites in Saxony (mining legacies no longer administered by Wismut on June 30, 1990 and are not in the responsibility of the Wismuth GmbH), the federal government and the Free State of Saxony signed an administrative agreement in September 2003. Financing is provided by both sides up to 2012 to 39 million euros each. By the end of 2010, a total of 58 million euros was spent. In its capacity as project executing organisation Wismut GmbH is tasked with the proper conduct of remedial works.

Outlook From a present-day perspective, core rehabilitation

tasks will be completed after 2022. Following that, post-remedial and long-term tasks will have to be addressed. Such tasks include:

Inspection and repair of covers on waste rock piles, tailings •management areas, and the fill body atop the backfilled Lichtenberg open pit,

Treatment of contaminated flood water and seepage, •

Safeguarding of mine workings to be kept open in the long •term,

Environmental surveillance (monitoring), •

Repair of surface damages, and •

Long-term data management.•

CELLER BRUNNENBAU in Madagascar – Exploration of a Bitumen Deposit

Project DescriptionAssignment

celler brunnenbau was able to establish itself against 19 competitors in April 2009 and was assigned to drill out 18,000 core drilling meters in bituminous sandstones in the wireline core barrel drilling procedure HQ3 by TOTAL E&P Madagascar. In total, approx. 130 drill holes up to a maximum depth of 450 m were planned. The aim was to keep to a time limit of twice six months, interrupted by the rainy season from November to April.

PartnersIn January 2009, celler brunnenbau made a 5-day

probing trip to Madagascar to meet up with a company that had already pre-qualified in the ongoing tendering process. A direct application was no longer possible for celler brunnenbau since the tendering process was already under way.

With the intention of initiating the Joint Venture Bemolanga with this partner, celler brunnenbau was, on the one hand, able to ensure the legally compliant participation in the tender and, on the other hand, pledge the French managed local logistics company FOREX SARL. By means of the intended rental of a drill rig from the governmental mining organisation OMNIS, celler brunnenbau would recognize the national interests of the Republic of Madagascar in this prestige project at an early stage. Contracts with these partner became effective at the contract conclusion of TOTAL with celler brunnenbau on 29th April 2009.

Water is one of the most valuable resources of our planet. Humans, agriculture and many industries depend on a steady water supply. celler brunnenbau gmbh & co. kg makes that possible worldwide. The drilling technique of the family business founded in 1975 is applied in over 30 countries. Our sustainable quality and reliability render our experts sought-after consultants and partners for well and drilling projects of any scale. By experience, the water industry, energy suppliers and the industry rely on drilling expertise from Celle. Such as the mineral oil concern TOTAL in France that entrusted its drilling operations for the exploration of its bitumen deposit in Madagascar, which was globally tendered in January 2009, to celler brunnenbau.

Apart from the drilling operations, the article especially describes the inbound logistics, which are focussed on the project start with regard to deadlines. The consignment of sea and air freight to Madagascar as well as the following coordination of transports in Madagascar represented a special logistic challenge in this case. The responsible handling of resources in Madagascar is underlined by a very extensive HSE system in the entire course of the project. The article also exemplifies the measures concerning health protection, industrial safety as well as environmental protection.

by Dr. Christoph Ganzer celler brunnenbau GmbH & Co KG | Germany

GeographyThe insular state of Madagascar which has been

independent from France since 1960 is the fourth biggest island on earth. It is located east of Africa in the Indian Ocean. The Strait of Mozambique separates Madagascar from the African continent. The Comoros, located in the north, as well as Mauritius and Réunion in the east are well-known neighbouring islands of Madagascar. There are approx. 21 million inhabitants. The capital Antananarivo with its approx. 1.5 million inhabitants is located centrally in the elevated plain at 1,100 m above sea level. The island’s north-south extension is approx. 1,600 km, the east-west extension is approx. 600 km. The road network of the 540,000 km² island is subdued with aprox. 50,000 km of which only approx. 5,000 km are asphalted.

The project area of BEMOLANGA is located 300 km west of Antananarivo. The nearest port can be found in the city of Maintirano, 150 km west of the project area.

DepositThe deposit on the mainland consists of three sandstone

layers up to a dimension of approx. 40 m, which carry bitumen and are separated from each other by layers of clay. The deposit extends over the entire west coast. The governmental mining organisation OMNIS is the leading authority for the allocation of licences for the exploration of strategic resources, including mineral oil. The area of exploration is divided into exploration blocks and

33Issue 02 | 2011



extends over the entire west coast (see image 01). The exploration rights for exploration block no. 3102 with a size of 7,175 km² are shared by the companies MADAGASCAR OIL and TOTAL E&P MADAGASCAR, the latter being the operator.

The oil reserves of oil (P50 ) with a density of approx. 8 – 13°API are indicated with 16 billion barrels of OIP (Oil in Place). For comparison: the global annual consumption amounts to approximately twice that amount. Bituminously bound oil of this density is heavy oil and requires a special mining process for its exploitation by means of open cast mining or superheated steam injection for condensation.

PreparationTasks of the partners

celler brunnenbau as a drilling contractor had the operative and financial lead management in the Joint Venture Bemolanga. It placed the project management and the drill superintendent for each drill in the corresponding shift as well as the head mechanician. The business relationship with the joint venture partner FOREX was based on a pure renting for the provision of vehicles and staff for the entire logistics as well as the cementation of the drill holes and the pulling out of the casings. For this purpose, a PRINCESS drill rig of Chinese build was used. The governmental mining organisation OMNIS was contractually committed to provide a drill rig, an exploration drill rig CS14 by Atlascopco and the operating drill team. The fact that it was of the same model as the celler brunnenbau drill rig promised to reduce the expenses for repairs and maintenance as well as the spare part inventory.

1)Proved, Probable, Possible - P90, P50, P10(Proved, probable, possible reserves) The actual amount of reserves will never be exactly detectable, but estimates can be carried out. Thus, the expected amount of reserves is determined with the aid of 3 index numbers:

Proved reserves (P resp. P90) The smallest number: the reserves of which geologists are 90 % sure that they exist (sometimes a 95 % probability is indicated and named P95).

Probable resp. proved + probable reserves (2P resp. P50) The average number (average): the number which indicates the actually existing reserves.

Possible resp. proved + probable + possible reserves (3P resp. P10) The highest number: the reserves of which geologists are 10 % sure that they exist (sometimes a 5 % probability is indicated and named P5).2)API degree (American Petroleum Institute degree) is a conventional density unit for crude oil, commonly used in the USA. It is globally applied for the characterization and as a quality measure of crude oil. The API degree results from the relative density of the crude oil at 60 °F (15 5/9 °C) referred to water by API degree = (141,5/rrel)-131,5 . Crude oil is indicated as „light“ above 31.1 °API , „medium“ between 22.3 °API and 31.1 °API and “heavy” below 22.3 °API. The API degree is generally added to the type name.

TechnicsDue to the performance requirements of 18,000 drill

meters in 2 x 6 months, celler brunnenbau decided to drill actively with two drills in 2 shifts around the clock 7 days a week. For this purpose, a new Atlascopco exploration drill CS14 was purchased and another one rented from OMNIS, the governmental mining organization in Madagascar. The core drilling equipment was acquired from DATC, a company from France, via a German importer. In 2010, this equipment was complemented with a core drilling equipment from Atlascopco. The special thing about the core drills was the customer’s requirement to exploit all the cores in a transparent liner. With this system, the drilled bitumen layers can be sealed against gas emission and still be visually examined. The drilling fluid system consists of 3 x 1m³ open tanks which were designed in a pilable way for transport reasons, desander for the separation of the

Image. 1: Project area

34Issue 02 | 2011



abrasive solid fraction as well as a GRINDEX mud pump to mix the drilling fluid additives. The entire drilling equipment was available for both drill rigs.

The joint venture partner provided the entire fleet for the logistics. Trucks with a loading crane as well as a tank truck for the disposal of the bitumen which had been separated from the fluid. In addition, he provided trucks with a loading platform for the transport of the drill rods, the fluid tanks, the water IBCs and the liners as well as the drilling tools. Generators for the electricity supply of the pumps and lighting were designed as trailers. Later, two off-road vehicles were exchanged against small trucks for the transport of the team.

StaffThe number of staff and staff qualification depended on

the following factors:

Task•

Shift operation (2 x 12h) •

Fly in / Fly out operation (4 weeks in, 2 weeks out)•

Operating machines•

Assignment conditions (climate, culture, task, •accomodation)

This resulted in a team size of 37 people on the construction site under the management of celler brunnenbau. The cb team changed at a 4/2-week rhythm, every 2 weeks only 2 people changed. This procedure avoided the loss of information due to changes. The local staff changed at a 4-week rhythm. Chart 01 shows the manpower in an overview, differentiated according to the

partner companies. The inclusion of local staff under the project responsibility of cb is very obvious. The 8 cb and FOREX expatriates were in charge of 29 local staff.

Every project, especially a project abroad, makes special demands on the staff and the operating machines. So the project planning and preparation are the key phases of an economic and operationally safe project execution. The following preparations were carried out:

TEST OF THE DRILLING EqUIPMENT • – The entire equipment was submitted to a last test before the shipping. The team and the participating representatives of the supplying companies tested the drilling and the equipment on the grounds of a befriended mining company, which offered comparable geological formations.

BRIEFING AND TRAINING AT THE DRILL RIG• – During the test week, the operating staff was trained and briefed at the drill rig. The customer made use of this test week to survey and approve the equipment.

OCCUPATIONAL HEALTH SCREENING• – All of the staff of celler brunnenbau scheduled for the operation in Madagascar were examined concerning their suitability for their assignment abroad (G35) at the Works Medical Office (BAD) in Hanover.

VACCINATIONS FOR MADAGASCAR • – All staff received the required vaccinations within health protection.

INTERCULTURAL TRAINING• – An understanding of the country and its people is always helpful during a stay in foreign cultural areas. The drill superintendents were in charge of Malagasy staff. So it was very important for celler brunnenbau to strengthen the staff’s intercultural competence and prepare them accordingly for their stay in Madagascar.

Image 2: fleet

35Issue 02 | 2011



LANGUAGE TRAINING • – In connection with the intercultural training, our employees also successfully completed a 2-week English language training before their first operation. This language training was continued with a 6-week intensive course during the winter months.

FIRST AIDER EDUCATION • – TIn spite of having medical care in the camp and emergency plans for the evacuation of casualties or sick people, the drill superintendents were educated as first aiders.

PSA (PERSONAL SAFE EqUIPMENT)• – Naturally, all cb employees were equipped with tropicalized workwear and protective gear.

Logistics (Mobilization)Due to the very tight time frame between the assignment

and the start of drilling, the logistics streams had to be coordinated so that they took place parallelly timewise. It was the aim to start drilling on 20th July 2009 considering the equipment delivery times, the limited loading capacity of the container trucks as well as the inability to pass the Manambaho river due to flood water. The customer had built a bridge across this river in 2010 so that it was possible to manage the demobilization of the logistics vehicles directly from the project area to Antananarivo in 2010. Thus, the costs for transport via ferry could be saved.

SEA TRANSPORT FROM HAMBURG TO MAHAJANGA1. – On the seaway from Hamburg to Mahajanga, seven 20-foot containers with a drill rig and the equipment were shipped first (see image 03). After the intermediate handling in Dschibuti, the container ship of the French shipping company had to pass the coast of Somalia. It reached the port of Moroni on the Comoros without incidents and the load was handled onto a feeder ship to Mahajanga in Madagascar.

AIR FREIGHT FROM HANOVER/PARIS TO ANTANANARIVO2. – Due to the long delivery time of the plastic liners, a partial load was priorly sent to Antananarivo by air freight. It was then transported within the mobilization of the JVB partner under #4. This lot size was prognosticated so that the drilling operation was provided for up to the time that the second sea freight #5 would reach Madagascar with the remaining liners (6,000 pieces in six 20-foot containers).

LAND TRANSPORT FROM ANTANANARIVO TO 3. MAHAJANGA – The joint venture partner had scheduled his mobilization to the port of Mahajanga so that his drill rig, a tractor and the OMNIS drill rig, which was packed in a container, arrived in Mahajanga at the same time as the first sea freight from Hamburg.

SEA TRANSPORT FROM MAHAJANGA TO MAINTIRANO4. – The entire equipment from #1, #2 and #3 was then stowed on a ferry (landing craft), transported from Mahajanga to Maintirano and unloaded there.

LAND TRANSPORT FROM MAINTIRANO TO BEMOLANGA 5. – In Maintirano, the containers were put into intermediate storage and driven to Bemolanga to the workshop, which was to be established there, with a local freight forwarder in several transports.

LAND TRANSPORT FROM ANTANANARIVO TO 6. BEMOLANGA – At the departure of the ferry #4, the convoy of off-road vehicles and vehicles suitable for mudflat set off from Antananarivo to Bemolanga. It took the trucks and off-road vehicles three days for the 500 km roadway. The road, which was asphalted at the beginning, soon turned into a bush track, which was very difficult to pass due to the rainfalls.

OperationSince the drill holes were close to the surface (the

deepest drill hole was 242 m deep), the drilling operation was characterized by continuously repeated work steps. This was especially helpful concerning the education of the local drillers because routine develops the positive learning success by permanently repeating the work processes.

MOBILIZATION TO THE DRILL LOCATION – The drill locations were all prepared by the customer and the drilling entry points mapped. Before each drill location change, the project manager of the Joint Venture Bemolanga approved the accessibility of the drill locations and the drill location in its composition. At the crossings, the shoved roads of access were equipped with sign posts of the drill locations to be reached for better orientation.

ESTABLISHING THE DRILL LOCATION – Each drill location was established according to a positioning plan agreed with the customer and accepted by the customer’s supervisor prior to drilling start. First, the trailer-mounted drill was positioned, the mast was set up and the drill was secured in its position. According to the depth, two to three cleaning tanks with a capacity of 1 m³ each were placed parallel to the drill. The drilling fluid was piped from the drill hole into the first tank via the swivel head screwed onto the casing pipe. A GRINDEX suction pump, which was installed in the first tank, transported the drilling fluid into the second cleaning tank via a desander, which separated the abrasive fines from the fluid. From there on, the self-suctioning Triplex drilling fluid pump of the drill pumped the drilling fluid into the drill hole with 40 bar.

PLACING THE HW CASING – The task of the 41/2“ casing (HW-Casing) is to protect the drill hole in the loose rock from belatedly falling rocks and discharge the drilling fluid in the annular space between the core drilling system of levers and the casing via the casing swivel head. Depending on the overburden, up to 20 m of casing were introduced.

CORE DRILLING (HQ3) – The customer wanted a coring exploration from the first drilling meter. So it has been cored up to the in-situ rock mass. The casing was sealed to the rock mass with clay and the casing swivel head was installed. The core barrel system HQ3 is designed so that the inner tube can accommodate a liner of steel or plastic which the core is introduced into forcedly while drilling.

First, the drill hole was flushed free with the drill rods until the bottom of the drill hole was reached for further coring. In 3-meter core drilling lengths, the inner tube was pulled to the surface (see image 07 ) over an overshot (2) from the outer tube (drill rod) by means of a winch. An priorly prepared inner tube with an empty plastic liner was exchanged with the full inner tube after disconnection and let back into the drill hole (1) until it latched itself again (8) through its gravity in the outer tube (10) (drill rod). The plastic liner (12) with the core lying inside was recovered from the inner tube and handed over to the customer’s geologists for testing and further processing. The 3-meter plastic liner of polycarbonate with 63 mm internal and 65 mm external dimension was able to accommodate the 61.2 mm core without difficulty. It only became problematic when the bit was not true to size. With a core diameter below 61.0 mm, the conus of the core lifter was no longer able to break the core to pull it. This bore the risk that the core might stay permanently bound with the rock mass and that the inner tube might be pulled to the surface without the core. Here, the sure instinct of the drillers, who successfully palpated the successful „core catching“ by feeling the rope, was of great importance.

DEMOBILIZING FROM THE DRILL LOCATION – After having reached the final depth determined by the geologists, the drill hole was rinsed and the drill rods were pulled out. The entire drilling equipment was loaded for transport to the next drill location together with the logistics team.

MOBILIZING TO THE NEXT DRILL LOCATION – Each drill rig was assigned to a truck with a loading platform as well as another truck with a crane for the transports between the drill locations. In the course of the project, it was possible to reduce the initial mobilization from one drill location to another from 6 hours to less than 3 hours.

LOGGING – Another subcontractor from the customer’s side carried out the geophysical logging of the drill hole. The tasks in their chronological order were scheduled in the morning meetings of the customer with all subcontractors.

CEMENTATION AND PULLING OUT CASINGS – The cementation of the drill holes was to separate the layers carrying bitumen again. The joint venture partner’s drill rig was planned for a possible re-drill of the drill holes. Due to the technical difficulties with this machine, celler brunnenbau decided to import a self-propelled drill rig from their own company to Madagascar in a project break. An AGBO G200 was retooled as a combination drill rig for well sinking and exploration drilling. This cost intensive measure very quickly became a very economic one since the AGBO drill rig was also able to core wireline at a high performance level during the standby times of the rented OMNIS drill rig. It was even possible to convince the customer that the drill holes could be cemented with a light NORIP tube system without a drill rig. Further equipment for the second project phase was shipped to Madagascar in the winter months together with the AGBO drill rig.

After the drill hole had been cleared for cementation by the customer, the cementation team came into action. The casings were pulled out with the AGBO G200 and the drill holes were cemented with the NORIP tube system in a contractor procedure.

HSECERTIFICATION – In 2009, celler brunnenbau was tested

and certified according the British Standard OHSAS 18001 (Ocupation Health Safety Assessement Series). This certification decorates the quality and work protection management system of celler brunnenbau and made it possible to issue a joint bridging document with TOTAL

for the entire drilling operation under the responsibility of the Joint Venture Bemolanga. This bilingual document in German/French contained all work processes, risk analyses and measures for hazard prevention.

MEASURES – Generally, the same work, health and environment protection measures were applied as it is customary in Germany and France. Some examples:

Wearing PSA, Personal Safety Equipment•Safety instructions before each shift (Safety Meeting)•Collecting environmentally dangerous substances – •disposal in AntananarivoExclusive usage of tested lifting and lashing straps•Electrical and mechanical testing of the machines by •independent Malagasy expertsVehicle monitoring via GPS surveillance – maximum •speed of 50 km/h and destinationRadio equipment in each vehicle•Mobile radio equipment at each machine and for each •drill superintendentWelding permit•Alarm and rescue exercises•Attendance and absence check at the camp entrance •by means of a plug-in boardPermanent presence of the customer’s work safety re-•presentative at the drill location

INCIDENTS – Some incidents and almost accidents were registered in 2009. Three employees were stung by scorpions. Due to the correct treatment with an antidote by the camp doctor, the employees were fit for work again the next day. A heart attack and an attack of gout in the case of OMNIS employees in their leisure time prompted the OMNIS management to submit their employees to an additional and probably selective health check. This lead to a drastic reduction of the average age of the OMNIS drill team in Bemolanga. In spite of a time-intensive job training of the new drillers by the drill superintendents of celler brunnenbau, this measure finally lead to a significant performance increase of the OMNIS drill.

In 2010, neither a single incident nor an almost accident was registered.

REPORTABLE ACCIDENTS – In the entire project duration, not a single reportable accident was registered under the responsibility of the Joint Venture Bemolanga.

HSE AWARD – The Joint Venture Bemolanga was awarded by TOTAL with a safety prize for the implementation of the HSE bridging document. The Malagasy HSE manager of the joint venture outlined the safety measures and work safety instructions in the national language on a board as a safety toolbox (see image 10). This safety toolbox was placed at the entrance to each drill location and served as an instruction base for the safety instruction before each shift.

AccomodationAll employees were accomodated in a container camp, at

peak times it held almost 400 people. The camp had its own water treatment and power generation with diesel generators. Communication was possible via mobile networks of two providers, transmitters were installed close to the camp by the providers especially for this purpose. Catering was possible around the clock. Food was flown in by airplane from the capital. The camp was supplied at least once a day.

PerformanceAccording to contract, 9,000 coring meters were to be

drilled per ½ year with a core recovery of 95 %. In 2009, this target was reached thanks to the performance of the cb drill rig. The permanent geological evaluation of the core samples in the customer’s laboratory in Antananarivo resulted in a change of the drill programme in 2010. The original drill programme of 9,000 coring meters in 2010 included a smaller number of drill holes at a higher final depth. Actually, 34 drill holes at a considerably lower final depth and 2,000 coring meters less were drilled. This option of the customer was contractually stipulated and accordingly financially compensated.

The performance difference between the OMNIS and the cb drill rig can be explained by the long standby times of the OMNIS drill rig due to technical defects. The correction of these defects was not precisely favoured by the decision-making processes within the government agency. Even the performance-related rental price was not able to bring about a repair decision in Antananarivo, especially before a weekend

Conclusionceller brunnenbau accepted the logistic challenge after

signing the contract in 2009 in spite of the tight time frame and successfully reached the drill target in the 2009 season as well as in 2010. The education and instruction of the drill team by our drill superintendents, the HSE measures and the mechanician performance for the warranty of a high availability of the drill rigs show a continuous increase of performance without work accidents. The permanent optimization of the logistics to provide for the mobilization between the drill locations reduced the non-drill time. In addition, the contacts of the project management towards the government agencies and institutions, local organizations, traders and freight forwarders helped to fulfill the contract within this short project time in an economical way.

USE OF DIRECTIONAL DRILLING FOR UNDERGROUND ExPLORATION DRILLING

Potash mine in SigmundshallThe potash mine in Sigmundshall is one site of the K+S

Potash company. It is located northwest of Hannover, near Wunsdorf. The mine, which was added to the Steinhuder Meer-Bahn in 1906, was established in 1896 as the “Potash drilling company Wunsdorf”. The deposit has been explored by the Sigmundshall, Kolenfeld and Weser shafts.

Since March 2007, the Thyssen Shachtbau Company had been subcontracted to conduct exploratory drillings with the counterflush- and cable core method, both horizontally, as well as vertically with corresponding deviation drillings. The exploratory program Weser poses high demands on personnel and the applied technique.

Background and GoalSince 1898 the potash works in Sigmundshall have

been mining potash and magnesium salt in the salt dome Bokeloh, mainly for fertilizer and industrial salt production. In a district of approximately 2 km² northwest of the salt dome in the area of the Weser pit, no comprehensive exploration was done in depths below 725 m ground level. Up to the year 1923, the periphery of the mine shaft Weser had been excavated in deposits with different levels of the potash seam „Ronnenberg(sylvit)“ and „Stassfurt (Hartsalz)“. These locations had been considered in the planning of drilling design. The current connection to the Sigmundshall shaft is the 500 m level, from which the drilling exploration had to be started.

POTASH MINE IN SIGMUNDSHALL

Due to the stratifications and the steeply inclined, partly heavily folded layers, a direct steep downward drilling in the subjacent structures would have led to abrandant, acute-angled seam passages or sections. Furthermore the basic question was, whether, in addition to the supposed structures at the north side of the salt deposit, there would be other, undetected and economically recoverable potash deposits in the core area of the salt deposit. The exploration of these areas through drilling would have been very complex and would have required several setups. Therefore it was very helpful, that within the framework of a research project, it was possible to test a sensor for directed radar measurements in real conditions. The sensor was in the last phase of development.

The requirements for the technical implementation of the drilling programme was developed from two exploratory goals, i.e. large-scale radar detection of the salt deposit core and drilling exploration of the side deposits, with the following steps:

Conducting vertical drilling from the 500 m level, with a 1. diameter of 98 mm for the insertion of the radar sensor.Radar measurement of vertical drilling for the 2. exploration of the salt deposit core.Drilling of fan-shaped deflectors from vertical drilling 3. in the north-east direction with ascending course.

43Issue 02 | 2011



On the basis of the results of the radar measurement, it was possible to work on determining the borehole courses for the exploration of structures at the north-east side. As there were no hints about further, undetected seam structures in the deeper central section of the salt deposit, no further exploration was done.

Technical equipmentThe technical equipment used for

the task is introduced as follows.

Requirements concerning the drilling unit:

Drilling method: Wireline core Nq•

Planned depth: max. 1.500 m•

Drilling diameter: 85 mm•

Application of a drill motor for •deflections: 2° on 10 m

Applied drilling unitA drilling unit of Hütte company HBR 201, with the

following technical parameters was used:

Carriage length: 5.260 mm•

Feed length 3.600 mm•

Feed force: 200 kN•

Retraction force: 100 kN•

Top drive: •

Torque max.: 9.300 Nm•

Rotations max. 370 rpm•

These parameters allowed for smooth drilling with 3.0 m long drill rods, up to the required depth of approximately 1,500 m and the maximum of the deflection.

Example: max. driving power: 20 t•

Drill string: 12 t•

Friction resistances of a max. 30% in the deflections :3.5 t•

Drill string/InstrumentNRQHP rods of the Longyear company were used in the

applied drill string. Compared to the normal NQ rods, the advantage or important characteristics are that a more stable rodding connection is reached, due to the used thread type. In addition, the connection can be screwed with a lower torque, which leads to a lower stress and higher life time. This rodding type also allows for drilling with an incline of 2° on 10 m. Diapax drill bits were used for cutting in rock salt. These drill bits have proven their worth in all previous applications in potash and salt rocks.

PumpIn order to achieve the needed flow rate of the mud for

usage of a drill motor, a Triplex pump of Oilwell company with a maximum of 320 l/min was used.

Directional drilling equipment (DDS Directional Drilling Service Co)

The DDS steering tool, measuring probe, consists 1. of inclinometers, magnetometers, sensors and corresponding control electronics. The measuring probe sends data to the interface unit through the cable (active control), where the data are processed with the help of a computer.

The measuring probe is connected to the computer by 2. the interface unit. Here, all standard data obtained from the steering tool, like borehole gradient, toolface and temperature are recorded, processed and analyzed, and the current depth, position of drilling in azimuth, etc. are calculated with a computer programme. Through a connected printer these data can be printed at any time. In order to continuously check the drilling course, the 3. driller control stand is connected with the interface unit. The driller control stand shows the current position of the measuring probe, i.e the inclination, azimuth and toolface to the drillmaster.The controllable drill motor, downhole motor with 4. chisel, is applied in fields, in which a high accuracy of the borehole course is required and cannot be achieved with other methods. This motor has a built-in adjustable inclined connection (Bent Housing). Before

the start of the directional drilling, a matching between “highside” and the measuring device is done. The 300 l/min flow rate needed for the operation of the drill motor is covered by the application of a corresponding pump (see above).

A 2 7/8“ Motor (l= 4,4 m, approx.. 150 kg) with a torque of 635 Nm at 300 rpm and 300 l/min is used.

Borehole safety in exploratory drillingsIn exploratory drillings extensive safety measures are

put in place, in order to ensure safety of both man and mine with regard to leakage of unknown fluids and gases,. During the exploratory drillings in the sites of K+S Kali Company, a stand pipe of a minimum of 5 m is set. This pipe represents the connection between the mountain and the actual safety set. In principle, the leak tightness of the cementation bonding between mountain and stand pipe is proven after the setting of the stand pipe. In order to do so, the 1.5 fold of the calculated hydrostatic pressure has to be applied as test pressure, according to the depth at the drilling station and the pressure run time of 10 min has to be kept.

The safety set consists of a T-piece with the safety valve, the full mouth plate, the blowout preventer (rodding preventer), the rodding valve (Kelly valve) and the rotary preventer. The rotary preventer does not belong to the safety group. In detail, these elements of the safety set perform the following tasks.

The borehole can be closed with a full mouth plate against escape of fluids and/or gases under the condition, that the drill string can be pulled out of the drill pipe. The preceding T-piece offers the possibility of preventing the escape of mud through the safety valve on one hand, on the other hand it is possible to start the needed pressure release. In case of danger, the annulus with the drill string that is still in the drill hole can be closed with the rodding preventer; the drill string itself is closed through the rodding valve. The rotary preventer seals the annulus during drilling between drill string and the open rodding preventer.

Project History

It was planned to conduct a vertical drilling with a depth of 700 m and a drill diameter of 85 mm in the drilling station, the former fan house, in a level of 440 m above sea level, with cable core method.

Despite the exact setup, regular measurements with a multishot revealed a considerable deviation from the plumb line and the direction. In addition, the directional deviation was exactly opposite to the planned exploration area.

After some considerations and discussions with the employer, we decided to apply the directional drilling set. Nevertheless, arithmetically speaking, there was the possibility to reach the first deviation point from the actual

run of the curve. In order to do so, we had to drill with the drill motor and corresponding angle, until we had again reached the vertical course of the drilling, before the first planned deviation point.

We started with a small setting angle of 0.78°, without success. After that we increased to 1.15°, 1.5°, but it was not possible to achieve the desired change in direction and inclination. In order to be back in the plumb line before the first deviation point, the route became shorter and shorter. In addition, the correction would have been too steep in case of a too wide angle. Nevertheless we increased to 2.38°, and we were finally able to register the change we hoped for. The change was optimal, so that we could quickly apply the wireline drill set, in order to deliver the desired cores.

Fig. 9:Course of the vertical drilling

48Issue 02 | 2011



After measuring the drill hole we extended to 98 mm. Thereafter the drill hole was measured with EMR (electro-magnetic radar). The four deviation points were determined after the analysis of the results of the EMR-measurement, according to the geological requirements and the technical possibilities. It was planned that from the vertical drilling, a deviation in the required direction would be drilled with a downhole motor and a setup of 2° to 10 m in four deviation points (at a depth of –320 m, –160 m, –120 m and –80 m).

In order to drill the deviations in the above-mentioned depths, cementation plugs had to be inserted in these areas. Starting at the highest depth, a cement suspension was pumped up to the deviation point, with the help of packer and cementation pipings. After its hardening, it was possible to drill the deviation from the plumb line with a drill motor and an adjusted angle of 2° from this newly generated borehole floor. Through continuous build-up, the route of the curve was easily carried out to up to 45°

Subsequently, a core route of approximately 500 m was sunk from a starting duct, with cable core method. The same procedure was used three more times, at -160 m, at -120 m and at -80 m borehole depth.

AnalysisAfter initial problems in the vertical area, all four

deviations were conducted to the full satisfaction of the contracting body. The goal was achieved and the required information was obtained from the selected areas.

Altogether approximately 3,200 m were drilled, out of which approximately 2,400 were cored.

Wheel loaders as a basis for blasting vehicles, armature drill carriages and roof bolting rigs, as well as auxiliary vehicles

IntroductionWith more than 200 staff, Paus produces construction

machines, lifting systems, industrial vehicles, as well as vehicles for mining and tunneling. For more than 35 years, Paus has been producing automobile techniques for mining. Apart from the known tailor-made special solutions for clients in mining, the following vehicle types are manufactured:

Tractor shovels up to 5,5 t load capacity•

Dump trucks up to 30 t load capacity•

Universa 50 and Minca as platforms for various constructional •systems

Telescopic –rotary arm loaders for various auxiliary •equipment

After a short overview over the development of blasting technique at Paus, the main focus of this presentation is on various applications of the telescopic rotary arm loader.

Development of Blasting Technique in Paus Company

In the mid-seventies, the first blasting vehicles of Paus were manufactured according to the OBA CLZ vehicle construction guidelines of that time. At the beginning these vehicles were only equipped with liftable working platforms, but were later upgraded with swivels and telescopic functions. (Picture1).

Paus manufactures automobile mining machinery and Moessinger+Wolter is a producer of drilling and scaling vehicles. This paper presents a review over the development of blasting vehicles and introduces a wheel loader, which serves as a basic unit for diverse applications in mining. The telescopic swivel loader can be supplied with various accessory equipment, which can either be fixed or exchanged with a quick change plate. After a description of the basic unit, accessory equipment is explained. At first the application as an explosives loading unit, as well as a self-propelled elevating work platform is introduced, followed by its operation as armature drill – and anchoring tool. The application as hammering scaling tool and service vehicle is also described. More standard equipment, such as shovel, fork tip carriers and other auxiliary equipment are also briefly dealt with.

Today, engineering of explosives loading vehicles is more sophisticated than before (Picture 2). Diesel-hydraulic or electro-hydraulic compressors are not only the norm today, increasing mechanization has also found its way through manipulators and Hose winch, particularly for charging of boreholes. Further developments have also affected filling of the Anfo container. The filling over a screw conveyor can be seen in picture 2. Other possibilities are the filling by a vacuum suction plant or through an intermediate vessel.

A further development in the field of blasting technique is the application of emulsion explosives. Here, Paus cooperates with notable manufacturers and offers a carrier for the installation of an emulsion unit. (Picture 3).

Wheel Loader as Basis for Various Applications

During the last 15 years, the telescopic swivel loader (TSL), which can be self-propelled from the carriage, was developed into a mining machine that is suitable for manifold applications thanks to a quick changing device. This variety and the synergetic effects with construction machines turn TSL into an attractive machine.

Description of the Telescope- Swivel Loader – Basic Unit RL 852 TSL

The wheel loader RL 852 TSL is driven by a water-cooled Deutz 75 kW diesel motor. Through the hydrostatical traction drive, optimum running speed is achieved, even in changing inclinations. Through the articulated steering (±40°) and the small dimensions (Picture 4), a small turning radius is achieved. Due to the oscillation of the rear axle (±10°), in connection with the four wheel drive, the TSL adapts itself to even difficult floor conditions. The loading plant can be swiveled by 90° into each direction, and heights of approx 5.5 m can be achieved through the lifting, as well as by telescopic movements (Picture 4). In order to increase stability, the swing axle is automatically locked in swivel angles of more than ± 12°. Furthermore, the load is optically and acoustically monitored.

Accessibility of components and ease of maintenance of the TSL are extremely high.

The TSL is equipped with a closed ROPS/FOPS cabin for heights of up to 2.6 m, an open ROPS/FOPS- operator’s cab is available for lower heights of up to 2.3 m.

Applications

Explosives vehicleA TSL with a quick change system was manufactured

as a loading vehicle for a mine in Saudi Arabia. The 150 l pressure vessel for Anfo is firmly built on the cage. A compressor with a diesel engine and a delivery rate of

Pic. 3Example of an emulsi-on explosives loading vehicle

Pic. 22008 – explosives loading vehicle with Hose winch and mixing device

51Issue 02 | 2011



1.8 m³/min at 6 bar is built at the rear. The remaining actual load on the cage with a filled pressure vessel for Anfo lies at 150 kg. The horizontal swivel range of the cage of approximately 2 m² lies at ±30°, so that a 6 m wide drift can be loaded from a standing position. The maximum achievable stretch is more than 7 m. A specific characteristic of the TSL is that it is approved as “self-propelled elevating work platform” according to EN 280. This means that not only cage movements can be controlled from the cage, but the entire vehicle can be moved and controlled in walking pace.

Platform operationApart from the elevating work platform with an actual

load of 500 kg, a further self-propelled platform is available. Hereby the actual load in the cage is 300 kg and the horizontal swivel range is ±90°, resulting in a maximum stretch of up to 10 m (Picture 6).

Even in an elevated swivel range it is possible to omit usage of stilts. In order to ensure stability in case of a blowout, only foamed tires are needed. An acoustic sensor monitors the permissible longitudinal and lateral inclination of ±5°.

52Issue 02 | 2011



Applications for the platform operation in mining operations are for example the temporarily abandoning, advancing air tubes and other ducts, as well as service work.

Anchor Boring Rig and Bar InserterOn the basis of the TSL, Mössinger+Wolter delivered

a diesel-hydraulic anchor boring rig and bar inserter for rotary drilling, with which drilling and anchor lengths of up to 3.5 m can be achieved.

The rollover swiveling angle at the end of the drilling jig lies at approximately 270° (Picture 7). The drilling jig can be swiveled, both vertically, as well as horizontally through hinged hydro-cylinders. A hydraulically driven compressor is installed at the rear. The boring and anchoring unit is operated with a remote control.

Further application possibilities are, for example, the setting of radial anchors, the blast hole and extension drilling, as well as heading in escape tunnels. Alternatively it is possible to use hydraulic and drilling motors and hammers, as well as electro-drilling motors.

Hammer Draw OffA particularly successful version of the RL 852 TSL is the scaler, which is

equipped with a hydraulic hammer at the end of the telescope. Up to 2010, one hundred pieces were produced in various versions.

In picture 8, the NPK GH2 hammer is firmly built-in in the scaler. Here, the telescope is extended and the driver is safe, as he sits far from the location for scaling the roof. The operation of the hammer is done from the cabin through a foot switch or a joystick. In addition, the number of blows can be varied according to rock conditions.

Hoses and cylinders are stored, protected by plates or tabs. The ROPS/FOPS driver’s cabin is protected by grids and strippers on the telescope. The clearing blade ensures a secure stand on the road.

With a swivel range of ±45°, a stretch width of maximum 9 m with a maximum stretch length of 8 m can be scaled roof. The hammer which rotates by 100°, can also be used for bouldering. Since the hammer can be rotated and the telescope can be swung around, a very good view on the chisel tip is achieved. Pic. 8

BucketA further accessory equipment is a 1 m³ bucket with

an actual load of 2 t. The maximum achievable height lies at approximately 5.5 m. The bucket is for example used in narrow roads, so that the mine cars can be loaded in parallel to rail tracks. Not only the space requirement, but also the road distance is minimized, according to the motto “pivoting instead of directing”. A further advantage is that, through the telescoping, an unloading over higher hurdles or a loading over lower hurdles is possible.

Fork TipsA fork tip carrier can also be attached to the quick change

plate (Picture 10). The permissible load varies according to the pivoting angle and the height between 700 and 2,400 kg. An overload warning device informs the operator both acoustically, as well as optically about loading conditions.

Heights of up to 4.5 m lower edge of the forks can be reached, as well as a lateral working area of a maximum of 10 m (tip of the fork).

Here, the motto “pivoting instead of directing” is also relevant. It is possible to take up the palette from the deposit and to load a truck without traveling.

ServiceA special anchor scroll trench shield was developed

for a potash mine (Picture 11 left) The protection shield of a cage can be pulled in, up to the level of the guard rail, so that the scrolls can easily be placed on the roof and can be unrolled left and right of the cage. The mat is fixed on the roof by pins. After the protection shield is lifted and the operator has entered the cage from the front, the cage is driven to the center of the hanging wall and the mat is bolted – starting from the middle in the direction of the blows.

The TSL is also equipped with supports at its engine, in order to be able to work in roads with an ascending slope of up to approximately 18%. At the front vehicle, a shield with slide bar ensures a secure stand on the bedrock.

The TSL shown in picture 11 at the right is in operation in a salt mine as a service vehicle. In addition to a 4 m³/min (8 bar) compressor, which is installed at the

rear, a lubricating unit (fat barrel) and an oil barrel is also available. Corresponding hoses are led to the cage. Three hose drums are installed at the cage. In addition, there is a hydraulically driven welding apparatus with a 230 V power outlet on the cage. The TSL is used for maintenance of stationary plants.

Further accessory equipmentFor the sake of completeness it should be mentioned that

for mines, which use the TSL both above and below ground (e.g. drift mining it is possible to add further equipment. For winter services it is possible to use snow blowers, snow plows and slat dispensers.

The following accessory equipment can be used for road building and maintenance:

Shield with slide bar•

Vibratory plates•

Power sweeper•

Load hook•

In addition, various bucket types are possible, like light goods buckets, bottom dump shovels and clamshells.

In summary, the telescope swivel loader is a universal mining vehicle, which offers unique kinematics and accessory equipment for each individual case.

JUNGFRAU – TOP OF EUROPE:World-famous names in tourism and technology united at 3.454 m

The lasting development of the Jungfrau region into a year-round nature experience is already underway. The aim of the building operations, which are taking place at an elevation of around 3,500 metres, is to implement a spectacular all-weather programme for the future. During the season, the Jungfrau Railways transport up to 5,000 visitors per day past the mighty trio of the mountain giants Eiger, Mönch and Jungfrau to the highest railway station in Europe. The company Frutiger AG was awarded the contract for the building works, which will allow the stream of visitors to be optimized. Ernst Zobrist is in charge of realizing the new infrastructure of this world of experience. The specifications that were defined by the customer are a challenge even for this experienced project manager.

100 years of Jungfrau Railways. The countdown has started. What was festively begun at the EXPO World Exhibition in Shanghai in the summer of 2010 will reach its crowning culmination on the Jungfraujoch on 1st August 2012. Between now and then there are still around 250 m of rock to be penetrated in the construction of the new visitor round-tour gallery – and a lot of work to be done. By the time it is finished, CHF 14.5 million will have been invested, and humans and machines alike will have been pushed to their limits: at present in three-shift operation – 24/7. Under the direction of the company Frutiger AG, Avesco is providing all the key devices, such as the drilling jumbo DD420 and the tunnel loader LH307 from the internationally renowned manufacturer Sandvik.

Already in the bidding phase, Frutiger and Avesco got in contact with each other about the project. Due to decades of previous cooperation between the two companies, they quickly reached an agreement and could start the necessary work as soon as the contract was awarded. Avesco immediately provided all the key plant and trained personnel, thus demonstrating its strong position on the market. „For this special assignment in continuous operation, I rely on the experienced Avesco mechanics. They are thoroughly familiar with the Sandvik machines“ says Ernst Zobrist, expressing his confidence in the chosen partners.

Transporting the heavy drilling jumbos and loaders to the construction site confronted the mechanics and the operators of the railway line with a particularly challenging task. In contrast, the logistics for the delivery of the Sandvik drilling bits – within 24 hours – is a standard job, performed almost every day. The low oxygen level at this altitude, however, troubles men and machines alike. For the machines, a drop in performance of around 10% per 1,000 metres in height has to be taken into account. Despite the high altitude, the Sandvik drilling jumbo DD420 drives the boreholes needed for the nightly blasting into the granite as if it were Swiss cheese. The permanent frost and the extreme weather take a greater toll on the miners than on their robust equipment from Sandvik.

Using the Sandvik underground loader LH307, as ergonomic as it is powerful, the excavated material is transported to the end of a 60 m tunnel and disposed of in an ecological way into a crevasse near the top end of the glacier.

Furthermore, a Sandvik DC121R drill rig with a special feed for anchoring, as well as Toyo hammer drills are in operation at the high-altitude construction site. The equipment used is complemented by the Sandvik drill steel.

Until the anniversary festivities on the top of Europe, all the participants will continue to pull together. Then, one would like to communicate the conclusion “E suuberi Sach!” – Swiss dialect for „a well-done job“ all over the world in many languages.

Frutiger AGThe company Frutiger AG, based in Thun,

is one of the leading construction groups in Switzerland. It was founded in 1869 and is family-run in the 4th generation by the owners Luc and Thomas Frutiger. In 2009, some 2,200 members of staff in the group‘s 26 companies achieved a group turnover of CHF 676 million.

High pressure filtration laboratory and plant testwork: TUBE PRESS

Why mechanical dewatering?In dewatering applications, the most important question is the cost involved to reduce the moisture content of

a slurry / suspension; both in regards to direct equipment investment and operation costs. The most cost effective alternative is an energy free process i.e. sedimentation. However, as particles get finer more energy has to be introduced to separate solid and liquid. Super fine material often needs a thermo drying step at the end to reach the process target. With the use of Mechanical Dewatering instead of thermal drying, significant cost saving and cost control is achieved.

The use of High Pressure Filtration often gives the final rest residual and cake features that the process requires with less energy usage. Reducing moisture is a question of energy added. A single full size Tube Press can operate with just 11kW installed power. With test work, basic data for the specific material can be obtained including: equipment selection, residual moisture, filtration capacity and basic plant scaling.

Laboratory test workAt the Metso laboratory based in Sala,

Sweden properties of a sample can be tested and evaluated including particle size distribution, viscosity, pH, settling, effect of pressure (vacuum – high pressure) flocculants, temperature and filtering aids.

With the Metso Piston Press the filtration characteristics under high pressure can be evaluated. The Piston Press is a standard laboratory filter, capable of filtering slurries at pressures up to 180 bars.

The fundamental basis of any Tube Press application is an accurate assessment both of the core process, and of the associated mechanical and operational criteria. Metso Sala has well equipped facilities, with personnel who have long experience of solid/liquid separation.

The pressure and air effect on residual moisture

With Tube Press Pilot Unit, full scale tests can be done to evaluate the effect of pressure and air drying. By the use of mechanical high pressure even strong capillary forces can be overcome. The additional use of air blow, where air is forced through the filter cake by hydraulic pressure, will further reduce the filter cake residual content.

Site test pilot equipment and features

The Tube Press Test Unit SC 500-12/75 is a mobile fully automated pilot plant used to evaluate filtration characteristics of a specific slurry at the customers site. The test plant is installed in a 20 ft container complete including Tube, media booster, feed pumps, air compressor, hydraulic unit, control cabinet, filtrate tank, etc. The container includes equipment to perform smaller scale tests with a piston press and laboratory equipment. The unit is equipped with sensors to allow for all necessary measurement of the filtration conditions, which will be the base for plant scale-up.

With the pilot unit process simulations can be run for all operating parameters which can be used in a full size plant including air-purge (pressing air through the cake) cake washing and cloth testing.

Tube PressThe Tube Press is a membrane type

filter press designed in cylindrical format and capable of operating at high filtration pressures up to 100 bar. The use of these high pressures enables a higher degree of separation of the liquid and solid phases.

The Tube Press is suitable for applications:

Alternatives to thermal drying•

Where the process requires very low cake moisture. •eg. smelters

Where cake handleability is critical. e.g. underground •slimes

Where filtrate is a valued product•

Where cake transport costs are significant•

Where cake is to be disposed of to landfill•

Principle of operationFiltration takes place between two concentric

cylinders. The outer cylinder is the casing, and the inner, the candle. The process slurry is pumped into the annular space between the filter media and the bladder. Hydraulic fluid, usually water, is then pumped between the bladder and the casing putting the slurry under pressures and causing filtration to take place. When filtration is complete the hydraulic fluid is withdrawn from the Tube unit using vacuum until the bladder is dilated against the casing.

The candle is then lowered to the discharge position and a pulse of air is blown between the candle and the filter media. This causes the filter cloth to expand, fracturing the cake which is discharged under gravity.

When complete the candle closes to the slurry fill position to repeat the cycle. Air purge and/or cake wash can be incorporated into the cycle. At the completion of the filtration element, air or wash fluid is pumped between the cake and the bladder which is then forced through the cake by a further application of hydraulic pressure to be incorporated into the cycle.

Reliable supportMetso specialists are experts in a wide range

of industrial processes. Our policy is to provide a thorough knowledge of our customers’ applications.

Research and developmentIt is Metso’s policy to continue to improve, thus

the performance of new materials is assessed with a view to greater efficiency and reliability.

After sales serviceOur after sales service provides you with fully

detailed operating and maintenance instructions, training, professional start-up services and technical assistance.

OpportunitiesIn many industries a liquid phase in the process

creates the need for liquid/solid separation so that the solids and/or filtrates so produced can be handled or disposed of.

“Traditional” mechanical dewatering often leaves the cake too wet or too sticky to handle effectively and usually demands further treatment such as thermal drying. The Tube Press, because of its unique design, will automatically and economically dewater most slurries to produce a clear filtrate and, without any form of thermal drying, a hard, surface dry cake that is convenient to handle as a product for immediate storage or for disposal.

Superior performancePorosity and cake moisture contents are

significantly lower than those obtained with low pressure filters, consequently filtrate recovery is high. Filtration is conducted at a pressure level where the

cake is produced as a hard surface dry, lump solid. Cake handling procedures are greatly simplified compared with those for low pressure filter cakes, which are typically plastic or paste-like and frequently surface wet.

Available data indicates that Tube Press output rates, in terms of dry solids per unit filter area, are much higher than for either vacuum or plate filter presses. This results both from the pressure dependence of filtration rates and the operational flexibility of the Tube Press which allows a closer approach to the optimum. Filtrate solids concentrations are generally zero, allowing immediate disposal or direct recycling.

Laboratory and rental serviceMetso can filter your product on both a preliminary

feasibility or on a full-scale production basis with either a lab-size unit or a production size Tube Press.

With well equipped laboratories, our experienced technicians will return a report, plus a small filter cake and filtrate sample to the customer for inspection.

It is essential that any sample provided for testwork is accompanied by details of its Safe Handling Requirements. If in doubt, the laboratory undertaking the tests will provide details of what is required under these regulations.

We can also provide Tube Press rental units for in plant testing. Each rig is essentially a fully operational single Tube Press plant, based around either a 500-series Tube Press unit.

All rental units are complete with support structure, together with skid-mounted pallet, for ease of shipment and installation, containing the functional services required for operation. The control system on each rig will allow for automatic and manual operation. Conventional filtration processes require continuous supervision and maintenance. The Metso Tube Press, however, is fully automatic which will yield big savings in manpower costs.

The Tube Press saves energy, lowers environmental impact and makes your process productive.

Emissions reductionThe Cat NOx-Reduction System captures and cools

a small volume of exhaust gas, then returns the cooled gas to the combustion chamber to reduce nitrogenoxide emissions. The CEM is an efficiently packaged aftertreatment unit that includes a Diesel Oxidation Catalyst (DOC), a Diesel Particulate Filter (DPF) and the Cat Regeneration System. The no-maintenance DOC assists in reducing the hydrocarbon within the exhaust stream and the DPF traps Particulate Matter (PM), or soot.

Under most operating conditions, exhaust heat continually oxidizes particulate matter collected in the DPF through a process called passive regeneration. However, if conditions are such that supplemental regeneration is needed, the Cat Regeneration System elevates exhaust gas temperatures to oxidize soot within the DPF. The Cat Regeneration System is designed to work transparently, occurring automatically without any interaction needed from the operator and regenerating when conditions are optimal.

Complementing low emissions, overall efficiency and fuel economy of the C9.3 ACERT engine is a hydraulically driven demand fan, which automatically adjusts its speed to match cooling needs. The fan reduces horsepower

draw, which further boosts fuel economy and allows more power to the wheels. Also, a new swing-out cooling fan package, with an easy-open latch, allows quick access to coolers for fast cleaning.

Operator amenitiesAt the heart of the M Series 2 design is the Cat control

system, which uses two electronic joysticks to provide complete, precise control of the machine. The control system results in nearly 80 percent fewer hand and wrist movements compared to conventional motorgrader controls; the net result is enhanced operator comfort and efficiency. The intuitive design helps both new and experienced operators be more productive.

The new M Series 2 motor graders also feature electronic vertical adjustment of the joystick control pods, allowing each operator to tailor joystick height for optimum control and comfort, resulting in greater productivity. Selectable blade lift speed modes allow more precise control to match lift response to the job. The spacious M Series 2 cab, with standard air conditioning, uses angled doors and a patented sloping rear window to afford excellent visibility to the heel and toe of the moldboard and to the ripper. In addition, a

250-amp alternator is available. To further promote jobsite safety, an optional rearvision camera provides a crisp, wide-angle view of the area behind the machine.

Integrated TechnologiesBeginning mid-2011, the M Series 2 models will offer

the new Cat Grade Control Cross Slope system. Cat Grade Control is a complete machine control and guidance system which integrates traditional grade control with standard machine components at the factory. This optional factory-installed and calibrated cross slope system provides automatic cross slope control capability, ready to operate from the moment it leaves the factory. In addition, Cat Cross Slope is fully upgradeable and compatible with AccuGrade™ systems to grow with customers.

In addition to Cat Cross Slope, the M Series 2 motor graders will also continue to offer the AccuGrade Ready Option which provides all the mounting hardware, controls and harnesses for easy installation of all AccuGrade kits.

Motor grader users can also utilize Cat Product Link*, which allows remote monitoring of equipment to improve overall fleet-management effectiveness. Product Link is deeply integrated into machine systems. Events and diagnostic codes, as well as hours, fuel, idle time and other detailed information are transmitted to a secure web based application, VisionLink™. VisionLink includes powerful tools to convey information to users and dealers, including mapping, working and idle time, fuel level and more.

Drive train and hydraulicsOperators can closely match machine ground speed

to the operating situation with the 8F/6R direct-drive powershift transmission, which uses the Cat Electronic Clutch Pressure Control system to modulate gear changes and Controlled Throttle Shifting for smooth directional changes without the inching pedal. Programmable Autoshift lets the operator match shift parameters to the application.

A manually controlled differential lock improves traction in adverse ground conditions. When engaged, a standard Automatic Differential Lock system locks and unlocks the differential as required to optimize traction while protecting the tandem chains and differential from possible damage. Multi-disc brakes at each tandem wheel provide large braking surfaces for sure stops and long brake life.

The new M Series 2 models are equipped with an advanced electro-hydraulic system for implement control, featuring an independent oil supply to prevent contamination from other systems and to assure proper cooling for extended component life. The load-sensing hydraulic system delivers consistent, predictable cylinder response and provides balanced flow, allowing implements to be used simultaneously with minimal effect on implement and engine speeds.

Durable structures and DCMThe M Series 2 front frame uses continuous top- and

bottom-plate construction for exceptional strength, and the rear frame features a robust box-section hitch design, cast axle mounting and integrated rear bumper for durability in the harshest applications, such as ripping.

The massive, one-piece, forged-steel circle is built to absorb high stress loads, and the circle-drive slip clutch reduces the potential for damage from horizontal shock loads. Six circle shoes keep the circle tighter, longer, to assure maximum control in finish-grading applications. The A-frame-type drawbar, using a tubular design for high strength and optimum durability, features a replaceable ball, removable shims (to compensate for wear) and top-adjust wear inserts.

The optimally shaped moldboard and large throat clearance keep material moving easily, resulting in less horsepower draw, more production and greater fuel efficiency. The moldboard side-shift system uses a well-protected cylinder mounted to the left to avoid snow-wing

interference. A shimless moldboard-retention system maintains blade adjustment over extended operating intervals for precise control. The retention system also permits easy adjustment or replacement of worn inserts to significantly reduce maintenance time.

NEW CAT®-621H, 623H AND 627H WHEEL TRACTOR-SCRAPERS

The new Cat® 621H, 623H and 627H Wheel Tractor-Scrapers are designed to deliver superior productivity and enhanced operator comfort and efficiency through the use of increased power and capacity, new structures,

electronic controls and ergonomic design. The new H Series designs change the way wheel tractor-scrapers look, run and ride—and increase their capabilities to move material at the lowest cost per ton.

H Series Wheel Tractor-Scrapers build on the proven durability and productivity of previous models with use of innovative technology. Sequence Assist and Load Assist automate many of the operator’s most demanding tasks, and when combined with Cat Grade Control, the new systems unburden veteran operators and help less experienced operators reach high productivity levels quickly.

With the H Series introduction, Caterpillar is offering the 621 in a push-pull configuration for the first time. The system enables two scrapers to work together when loading, rather than requiring a push tractor. Other scraper models have proven that the push-pull configuration is the low cost solution in many applications.

The new H Series machines replace the equivalent G Series machines when commercial production begins

FEATURE NEW DESIGNS AND TECHNOLOGY FOR HIGH PRODUCTIVITY AND OPERATOR COMFORT

in August of this year. Each of the three models will be available with engines that meet US EPA Tier 4 Interim and EU Stage IIIB emissions standards and with engines for use in other regions.

The 620H Series Wheel Tractor-Scrapers maintain the G Series configurations. The 621H is a single-engine, open bowl machine; the 623H has an elevating scraper and a single engine; and the open-bowl 627H has twin engines — one on the tractor and one on the scraper — and all wheel drive. Capacities are increased 2 cubic yards (1.5 cubic meters) to 24 cubic yards (18.3 cubic meters) for the 621H and 627H. The new bowl design is easier to load than the G Series bowl and has proven to enhance production. The 623H bowl maintains 23 cubic yards (17.6 cubic meters) capacity, but the elevator is stronger, more powerful and easier to adjust. The result is greater reliability and durability.

New engines and drive train controls improve performance and operator comfort

The new H Series wheel tractor-scrapers feature a more powerful engine in the tractor, and a more powerful engine in the scraper of the 627H. The Cat C13 engine in the tractor produces 407 hp (304 kW) — 18 percent more power compared to the G Series. And the C9.3 on the 627H scraper produces 290 hp (216 kW), an increase of 19 percent from the G Series machine. The new torque converter coupled to the scraper engine is designed to put more power to the ground.

New software ensures integrated performance of the engine and transmission. The 8-speed planetary powershift transmission hardware is the same as the G-Series unit, but new controls and software drive greater performance. The system manages the torque converter and transmission to provide smooth operation, which enhances operator comfort and extends component life. Performance on grades and coming out of the cut is noticeably better through sustaining torque through shift points. On flatter hauls, shift points are optimized for a balance between fuel economy and performance.

Complimenting the new power train and higher capacity are wet disc service brakes. The new brakes are similar to Cat off-highway truck brakes and deliver predictable and durable stopping power. The H Series machines also introduce engine compression retarding and the elimination of hydraulic retarding. Engine compression retarding can be modulated within low, medium or high ranges to optimize cycle times.

Technology assists operator and reduces rework

Caterpillar offers three new integrated technology options on H Series Wheel Tractor-Scrapers. Sequence Assist is available on all three models and uses integrated software and position sensing cylinders to automate many of the tasks an operator performs when loading, hauling and dumping. The operator simply sets preferences for bowl and apron height and subsequently pushes a button to ready the machines for loading, then for hauling, then dumping, and then the return to the cut. The system

automatically sets the cushion hitch, bowl height, apron, ejector and elevator. Sequence Assist comes with a convenient load counter for tracking material moved.

Load Assist is available on the 621H and 627H models. It builds on Sequence Assist by loading the bowl with the push of a button. As the machine enters the cut, the operator can activate Load Assist so the system takes over control of the cutting edge height, limiting tire spin based on integrated sensors and GPS technology to ensure consistent and full bowl loads. The operator is responsible only for the throttle and steering. Load Assist helps make inexperienced operators productive very quickly.

Cat Grade Control is available on all three models and is designed to work seamlessly with Sequence Assist and Load Assist. Using satellite positioning technology, the system ensures cut protection by limiting how deep the scraper will dig. The optional system is available from the factory and fully integrated into the machine. The system also puts the site plan in front of the operator for increased efficiency and elimination of rework. Another benefit of Cat Grade Control is site mapping using the scraper.

New cab and operator station — designed for wheel tractor-scrapers

The new cab is designed specifically to accommodate the tasks involved with operating scrapers. It‘s 21 percent larger than the G-Series cab, which gives the operator more room for movement and allows more window area for an expansive view of the work area. Also new and designed specifically for scrapers is the Cat Advanced Ride Management System. This new system, which is in testing and will be available soon after H Series machines go into commercial production, is a seat suspension that dampens vibration and prevents endstroke shock loads.

80Issue 02 | 2011

NEWS & REPORTS


As part of the improved ergonomics, the steering column and pedals align with the right front post of the cab. This puts the operator in a more comfortable position when the seat is turned 30 degrees. A T-handle implement control is designed to fit comfortably in the palm of the hand and is aligned with the seat armrest for comfortable operation. The new wheel tractor-scrapers also feature multifunction hydraulics. The optimized hydraulic system, which uses piston pumps rather than vane pumps, enables the operator to operate the apron, ejector and bowl height control at the same time for faster cycle times.

An integrated dash group offers displays for the optional Work Area Vision System (WAVS). Cameras on the machine provide views of the cutting edge, right side and rear. The system enhances safety and provides a new way to see the cutting edge during loading and to see to the rear of the machine when performing push-pull work with another scraper.

An optional powered access ladder facilitates getting in and out of the machine. The ladder raises and lowers, tucking up under the cab when not in use.

A new cushion hitch configuration also enhances operator comfort. The 620 Series hitch has two accumulators — one high pressure and the other lower pressure. The high pressure accumulator softens the ride when the machine is loaded, and the lower pressure accumulator optimizes dampening an empty bowl.

CATERPILLAR PUTS THE OPERATOR FIRSTWITH THREE NEW B SERIES ARTICULATED TRUCKS

Reduced exhaust emissions - Tier 4 Interim/Stage IIIB

The three B Series trucks will be available with Tier 4 Interim/Stage IIIB certified Cat® diesel engines for those countries that require them. Caterpillar has employed proven electronic fuel and air supply components for maximum reliability, with a modular after-treatment solution, capable of withstanding the arduous working conditions within construction projects.

Cat, Caterpillar

CATERPILLAR INTRODUCES THE NEXT GENERATION OF ARTICULATED TRUCKS. THE NEW B SERIES MODELS NOW INCLUDE THE 735B, OFFERING A 36-TON (32.7-TONNE) PAyLOAD, THE 740B WITH ITS 43.5-TON (39.5-TONNE) PAyLOAD, AND THE 740B EJ WITH POPULAR EJECTOR BODy, CARRyING A 42-TON (38-TONNE) PAyLOAD. ALL THREE MODELS ARE AVAILABLE WITH EITHER TIER2/STAGE2 EqUIVALENT OR TIER 4 INTERIM/STAGE IIIB CERTIFIED EMISSIONS CONFIGURATIONS TO MEET THE NEEDS OF CUSTOMERS AROUND THE WORLD. BOTH CONFIGURATIONS FEATURE REVISED TRANSMISSION AND TRACTION CONTROL SySTEMS THAT ENABLE HIGHER PRODUCTIVITy. THE NEW TRUCKS ALSO FOCUS ON REDUCING DRIVER EFFORT AND CUTTING OPERATOR FATIGUE THROUGH IMPROVED CAB DESIGN.

The result is a range of more powerful emissions-compliant diesel engines offering improved overall performance.

The systems employed on the Tier 4 Interim/Stage IIIB B Series trucks produce 90% less particulate matter (PM) and reduce nitrous oxides (NOx) emissions by as much as 50 percent. Emissions controls include a Diesel Particulate Filter (DPF) to trap soot. The necessary process of removing the soot is called regeneration. The “on-the-go” regeneration system allows the regeneration to take place without operator intervention and without

sacrificing working time. Regeneration can be completed in a number of ways, so that there is no need to change machine work patterns.

Optimized drive trainCaterpillar has further improved its six-wheel-drive

system. A new, fully proportional torque-distribution automatic traction control (ATC) system eliminates the need for any driver intervention to maintain maximum traction in difficult operating conditions. In the previous generation of articulated trucks, the operator had to manually engage floor- and dash-mounted switches to bring cross- and interaxle differential locks into play. With the new proportional ATC system, the truck automatically and constantly varies the required proportion of lock-up on both crossaxle and interaxle diff locks as underfoot conditions change. The automatic system leaves the

operator free to concentrate on driving the truck, without having to think about how to gain the best traction in different ground conditions. The new proportional ATC system works in harmony with the hydraulic steering system — without compromise in tight turning maneuvers.

The optimized proportional ATC system results in improved traction in all operating conditions for reduced cycle times and improved productivity. The automated system also reduces the possibility of system abuse, cutting wear and prolonging component life and reducing costs.

Caterpillar also has upgraded its field proven automatic transmission with the introduction of a number of significant technological improvements. These changes mean that gear changes are much smoother, as torque is maintained through each gear change, resulting in improved acceleration, especially on grades. Part

Throttle Shifting at lower speeds results in improved fuel efficiency and easier machine operation and provides the operator an automotive feel during gear changes.

The combination of increased engine power, improved transmission and proportional ATC results in improvements in machine and operator efficiency, cutting cycle times and boosting productivity. Smoother gear changing and reduced operator stress also improve overall operator satisfaction and comfort throughout the working shift.

Improved operator environmentThe B Series trucks are designed and built around

the operator. Behind the tough exterior, with its powerful new styling, integrated heavy-duty bumper and fully enclosed belly guards, the Cat truck offers the ideal operator environment. A new injection molded dash panel with revised trim provides an improved fit and a more aesthetically pleasing working environment.

The redesigned instrument cluster and fully customizable Color Multi-Purpose Display (CMPD) give the operator all of the information needed. Machine monitoring includes information as diverse as regeneration status, fuel levels, autolube status, load count and major component temperatures. The CMPD

also incorporates a live feed from the rear view camera, which is automatically engaged when reverse gear is selected.

The revised cab interior has a new headliner with switches for electric mirrors, regeneration operations and a heavy duty CD/radio. An upgraded driver’s seat with new multiple position adjustments improves the class-leading ride quality further, while new materials offer improved durability and long service life. A heated driver’s seat is available as an option. New operator and passenger grab handles improve stability when travelling over rough or sloping terrain.

The heating and air-conditioning system has been upgraded to improve efficiency and ensure the ideal climate in the cab. The engine hood raise switch is now positioned in the cab for ease of access and increased security. Other detail improvements include a new cab external grab rail, a repositioned ground level fuel filler for improved access, new machine width position marker lights and wider spaced turn indicators. High-intensity high-level work lights are now available as an option.

All B Series models are produced at Caterpillar’s state-of-the-art production facility in Peterlee, UK. The site has benefitted from unparalleled financial investment, extensive employee skills training and a full product validation process, to ensure that every truck exceeds the expectations of customers around the world.

HAVER NIAGARA T-CLASS®At bauma 2007 HAVER & BOECKER introduced the

prototype of the new HAVER NIAGARA T-CLASS®. This machine design has since been used continuously and developed further. Today the company looks back on a large number of satisfied customers worldwide.

HAVER & BOECKER recently introduced the NIAGARA T-CLASS® with a newly designed drive system, allowing more amplitude/rotary speed combinations than before. This in turn allows small cut sizes to be realized as well as difficult classifying jobs with large cut sizes. Further, the machine is equipped with a newly developed wear-protection system decreasing the replacement time of worn elements, thus reducing downtime.

HAVER & BOECKER REACHING NEW DIMENSIONS WITH THE NIAGARA T-CLASS®

Within the scope of the NIAGARA T-CLASS® concept, screening machines with widths starting at 2.40 meters were built in the first phase of expansion. After the introduction of a time and cost-saving modular construction system, machines with screen decks of almost twice the width (i.e. up to 4.20 m) can be built today at the plant in Münster.

A recently built 3.5-deck model D180 3000 x 7200 machine of this type was sold to German engineering and plant designer HAZEMAG in Dülmen. It separates 450 tons of limestone per hour at 25/15/8 and 4 mm. The dimensions of this screening machine are 3 m x 7.2 m, and the total screening surface amounts to 72 m². It weighs about 25,000 kg. In order to achieve the throughput and cut sizes requested by the customer, the NIAGARA T-CLASS® is

equipped with two bearings and a 75 kW drive unit. The screening machine is easy to access and to maintain, as the screen deck spacing is capaciously dimensioned. This provides ideal work conditions for the operating personnel.

The screen frame of the HSG machines is engineered in a traverse design. The deck structure is clamped onto the frame with a patented retaining bracket and without welded seams. The brackets form the mounting area for the screen panel support system. Through the positioning of the brackets, spacing of the longitudinal supports can be varied. Thanks to bracket shapes with horizontal and vertical mounting areas, this concept can be applied equally well to modular as well as side- or end-tensioned screen media. At the same time, these brackets also support a newly developed wear protection system (HAVER Snap Guard) of modular structure and allowing easy replacement.

HAVER & BOECKER demonstrates readiness for the future with their NIAGARA T-CLASS®, and continues to meet their customers’ growing requirement for customized solutions.

First Kleemann for Pinden GroupKENT-based Pinden Limited has taken delivery of its

first Kleemann crusher after many years’ operations using machines from an industry competitor. The Mobicat MC 110Z is one of a range from the Kleemann stable, which is sold in the UK by Wirtgen Limited. Pinden director, Steve Bishop, says the company opted for a change despite the machine’s higher cost, because of Kleemann’s reputation for superior build quality and its potential to deliver significant lifecycle fuel and other savings.

“We had the machine on demonstration, first,” says Bishop. “We were convinced we can make considerable savings in fuel consumption over the lifetime of the machine. We also found output to be higher, and the quality of product was better, than previous machines. Normally we would replace our crushers after three years; we expect to get five years from the Kleemann, with lower component replacement costs over that time. Wear parts are of a much better quality.” The Kleemann features a pre-screen which reduces fines before crushing, greatly reducing wear on the machine’s manganese steel jaws.

FIRST KLEEMANN FOR PINDEN

KLEEMANN MOBICAT MC 110 Z

The Dartford firm is part of a group of companies which include Syd Bishop and Sons (Demolition) Limited. Its Pinden quarry is the site of one of the South East’s largest processors of demolition waste for the construction industry, producing 6F1/6F2 materials for roads and other applications in accordance with WRAP specifications. Crushing facilities have to respond quickly to rising seasonal demand or peaks resulting from large individual projects. “We learned from the demo’ that the machine was capable of very high productivity. In fact one shovel alone couldn’t keep up with it,” says Bishop. “It means that, when demand [for material] is high, we can step up the output as necessary. The machine is also good from a dust-suppression point of view, which is important, as the site is regulated by the Environment Agency, being a receiver of hazardous waste.”

Kleemann southern area sales manager, Aidan Gillic, estimates the Mobicat should be good for annual fuel savings of up to £15,000 compared to competing machines. He says fixed jaw life could exceed 2,000 hours before replacement. “The geometry of the jaws also makes for a better end-product, which is easier to compact.

The Mobicat track-mounted single toggle jaw crusher is designed for pre-crushing natural stone and mineral construction waste for re-use. With a crusher inlet size of 1100 x 700mm, the Mobicat 110 Z is equally at home in quarrying or recycling operations. With its easy to transport size and weight of 45-50 tonnes, it has the largest scope of application of all mobile jaw crushers. The independently vibrating double deck pre-screen can be equipped with different meshes, according to the application. That way, pre-screen material can bypass the crusher or be stockpiled by the left or right side-mounted discharge conveyor belt, giving flexibility on construction sites where space is at a premium.

A 266 kW low fuel consumption, low noise and low pollution diesel engine, flange mounted hydraulic pumps and a coupled electricity generator deliver the power for the crusher and the electric drive for the belt, conveyors, conveying chutes, and screens.

A Siemens PLC control system with LCD display for manual and automatic operation come as standard on the Mobicat. A vibration-isolated, double switch cabinet housing and built-in overpressure system, along with connections for control cable to interlock auxiliary machinery and socket outlets for 230 and 400V components are provided.

Optional features include an electric or permanent magnetic separator and, on the 110, a single deck, longitudinally tensioned, large area vibration screen that can be hydraulically lowered for mesh replacement for quick changeover.

David Smith Contractors Ltd opt or more Volvo crawler excavators

VOLVO CONSTRUCTION EqUIPMENT

Established back in 2002 by Proprietor David Smith, the Company has evolved as a civil engineering and groundworks contractors undertaking bespoke projects for blue chip companies such as major retail outlets and superstores as well as the important oil and gas sector in the north of Scotland. Having purchased their first Volvo just five years ago, the Company has added to its portfolio of Volvo equipment with seven articulated haulers, an L120C loading shovel, a compact EC55B, a brace of EC210C’s and with the latest purchase, two EC240C and an EC290C. “We continue to have an excellent relationship with team from Volvo and the machines have been reliable and productive as well,” explained David Smith. “The opinion of my operators is equally important and they appreciate the high standard of operator comfort and overall performance we’ve found with the machines.”

FRASERBURGH BASED DAVID SMITH CONTRACTORS LTD HAS ADDED A FURTHER TWO, TWENTy FOUR TONNE EC240C EXCAVATORS AND A TWENTy NINE TONNE EC290C DIGGER TO THEIR INCREASING FLEET OF VOLVO CONSTRUCTION EqUIPMENT PRODUCTS.

The latest models to join the fleet herald new ventures that David Smith Contractors Ltd are entering into such as demolition contracts,crushing and quarrying contracts as well as a piling division. “Moving into these areas and to be able to offer our client base a complete package of services is vital for the long term,” said David Smith. “And to carry out the work in a cost effective manner means increasing the size of the machines and their capacities in terms of lifting and hydraulic capacity to suit the applications.”

One of the new EC240C’s has been modified by the customer to accept a bespoke piling rig which includes the fitting of an Indexator rototilt hitch and a hydraulically driven sheet piling head of the company’s own design and manufacture. The two tonne head runs off the EC240C’s hammer shear circuit requiring up to 230 litres per minute in high mode and can handle sheet

Arnold Plant Hire take two Volvo L50F loading shovels

VOLVO CONSTRUCTION EqUIPMENT

Looking to replace a pair of competitive models for an on going long term contract hire, the company settled on the Volvo product following a successful demonstration and competitive evaluation. “We’ve had experience with excavators from the Volvo range that gave us good reliability and availability but this is the first time we’ve switched to their loading shovels,” explained Arnold Plant’s Service Director Alan Laithwaite. “This coupled to the outcome of the recent demonstration and the very positive feedback from the personnel on site persuaded us in taking a leap of faith with the L50F’s.”

The pair of loading shovels has been put in charge of handling a wide variety of road materials ranging from road planings, aggregates, tar macadam to sub base and crushed concrete in a local authority’s stock yard servicing the demands from the Greater Manchester area. With the diverse range of product, both machines

have been supplied with several attachments that can be interchanged thanks to the Volvo quick coupler. These include a 1.4m³ general purpose and a 2.0m³light material buckets as well as pallet forks, complementing existing attachments on site including high tip and heavy duty buckets.

The L50F along with its smaller brother, the L45F, are two mid-sized wheeled loaders in Volvo Construction Equipment’s F series line up and share the same design of the rear chassis with its sloping engine hood - thanks to the transverse mounted 4.8 litre Tier III engine and hydrostatic motor, providing superb visibility all around the machine. The Volvo Care Cab was recognised as a key factor in selecting the L50F by the personnel on site who appreciated the high level of comfort, all round ergonomics, good functionality of the controls and air conditioning.

With an operating weight of 9430kg, the L50F has a generous full turn tip load of 5900kg with the optimum bucket size of 1.4m³ and the engine output of 117hp is superbly matched to the hydrostatic transmission allowing full power shift under load when changing direction and between speed ranges. As with its bigger brothers in the range the L50F sports a Torque Parallel (TP) loader linkage which provides smooth, parallel lift, high roll back torque and good lifting power throughout the lift cycle. The Volvo hydraulic attachment bracket facilitates the easy change over of attachments.

Established twenty years ago Arnold Plant Hire Ltd hires plant and machinery to the construction industry on long and short term contracts on a self drive nationwide basis. The company operates in excess of 100 items of mobile plant including mini-excavators from 1.5 ton to 7 ton; backhoe loaders; tracked excavators from 13 to 20 tonnes; wheeled loading shovels; telescopic handlers and hydraulic breakers.

The entire fleet is maintained in house by a fleet of mobile and workshop based engineers.

TELESTACK install 2 x Mobile Shiploaders and2 x mobile truck unloading units for loading

coal in Port of Vostochny, Russia

Mobile Shiploading SystemThe installed units consist of 2 x mobile systems to

load Handymax sized vessels at 1200TPH. The mobile shiploaders are 50 metres (170ft) in length with a range of movements to ensure adequate trimming of the vessel. The unique design of the Telestack conveyor systems allow for a full range of trimming capabilities, which are vital when loading these sized vessels. The telescopic feature allows the operator to telescope the inner conveyor (IN/OUT movement) so they can trim the vessel without altering the feed-in point or stopping the

Telestack Limited continue to excel in providing innovative mobile Shiploading systems to its worldwide customer base. This has been emphasised in the manufacturing and development of a fully customised MOBILE shiploading system for the Port of Vostochny, Russia. The mobile shiploading system is loading coal directly from trucks to 2 x mobile truck unloaders and 2 x 50 metre (170ft) radial telescopic shiploaders. Telestack Limited has enjoyed great success when installing coal handling facilities throughout the globe, with this project highlighting the mobility and flexibility of the equipment to meet the ever changing needs of one of the largest coal handling Ports in Eastern Russia.

The radial feature allows left/right movement via internal hydraulic drives to further enhance the trimming capabilities of the equipment, as the operator can radial from one fixed position, again without stopping production. These features, in combination with the luffing (raise up / down), allow for the most mobile and flexible loading equipment on the market.

As with the majority of Telestack equipment, the customer availed of the extensive range of options for this equipment to enhance the loading procedure and customise the units for the handling of coal. This includes

dust suppression measures throughout the equipment, including dust covers on the shiploader including the outer conveyor, telescopic dust covers on the inner conveyor and water suppression spray bars at the discharge point. These customised upgrades ensure every effort has been made to eliminate / reduce dust and spillage which are vital within the port environment. The mobility of the ship-loaders is done using a diesel engine driven tracked unit including a remote control for easy manoeuvrability around the site and to the next hatch during the loading process, see figure two.

Mobile Truck Unloader eliminates double handling

The 2 x dual access wheeled mobile truck unloaders allow the operator to discharge the coal directly from trucks or wheel loaders to load the vessel. This eliminates the double handling of the material and means a more efficient material handling process. The truck unloader consists of a heavy duty apron chain belt feeder to handle the surge of material from the trucks and transfer this onto the incline and then to the shiploaders, see figure three and four.

The dual access hydraulic raising / lowering ramps ensure an efficient cycle time for the trucks, as one truck is discharging the other is reversing into position for unloading as soon as the first truck is finished. This method ensures that production targets are maintained and are not hindered by the truck cycle times, which would be typical of single access truck unloaders, see figure five and six.

The unit was also installed with an overband magnet on the incline of the truck unloader to remove any metal from the coal before the material was loaded to the Handymax vessels.

The mobility and flexibility of these units ensure the loading process and production rates are increased / maintained for the operator. Telestack mobile bulk material handling systems are built to last, combining strength with the highest quality components available on the market. The success derives from achieving sustainable value for the client; using mobile bulk handling technology to enhance operational efficiency, minimise environmental impact and maximise flexibility.

From Florida to the Dominican Republic with Powerscreen

Powerscreen of Florida was founded in 1984 by Denis Grant and, over the last 27 years, it has earned a reputation as a leader in the sales, rental and aftermarket support of crushing and screening equipment in Florida, Georgia, the Caribbean, and Latin America. Located in Lakeland, Florida, the company has continually expanded its locations with support centers in Atlanta, Georgia, Haiti and most recently in Santo Domingo in the Dominican Republic.

The company prides itself on retaining a dedicated staff of employees with many years of service, which is critical to establishing strong relationships with customers. As a testament to this philosophy, its first employee, Karla Regan, is still with the company, serving as bookkeeper and office manager, and has been an integral part of the company’s growth and success.

The company grew steadily in the 1990’s and early 2000’s with sales peaking in 2006. Around this time, the company hired Rafael Bournigal, who is Denis’ son-in law, to develop sales in international markets, particularly the Caribbean and Latin America. Rafael

brought the management skills he had learned as a baseball executive for the New York Mets in charge of international scouting. The results were immediate. Export sales now account for approximately 50 percent of company revenue and helped offset the lower domestic sales as the recession continues to depress business in the south-eastern US.

The company has continued to explore markets outside the US and strengthen its presence in the Caribbean. Key to this plan was the opening of warehouse support center in the Dominican Republic. Under the name of a newly formed company, Powerscreen Caribbean, they will continue to provide customers in the Caribbean with an excellent level of service, thanks to a knowledgeable staff, full parts inventory, service department and a complete stock of equipment available for sale or rent.

In the past 18 months, Powerscreen Caribbean has had many successes in the Dominican Republic. One customer, Constructora Hermanos Yarull, bought 10 machines in the last year, to fulfil its commitment with Barrick Gold quarry. Constructora Hermanos Owner Pedro Yarull said,

Der Tagebau Schöningen im Helmstedter Revier wurde 1979 aufgeschlossen. Drei Baufelder erstrecken sich über insgesamt 600 Hektar Fläche unmittelbar an der ehemaligen innerdeutschen Grenze. Bis 2017 ist der Abbau terminiert – derzeit fördert die E.ON Kraftwerke GmbH pro Jahr rund 1,9 Millionen Tonnen Braunkohle zum Betrieb des Kraftwerks Buschhaus mit einer Jahresproduktion von 2,5 Milliarden Kilowattstunden Strom.

E.ON SETZT AUF GROSSDUMPER VON BELL Sparen im großen Still!

Im Kohle-Abbau und Abraum-Management werden im Tagebau Schöningen der E.ON Kraftwerke GmbH neben Bergbau-Großgeräten auch 6x6-Knickdumper eingesetzt.

Anlässlich der turnusgemäßen Erneuerung seiner Transportflotte entschied sich das Unternehmen nach eingehenden Tests für das 50-Tonnen-Topmodell von Bell Equipment: bis Mitte 2011 werden insgesamt 15 Bell B50D nach Helmstedt geliefert. Gemeinsam mit zwei verbleibenden Altfahrzeugen gewährleisten die Bell-Großdumper die Transportleistung der bislang aus 18 Vierzigtonnern bestehenden mobilen E.ON-Förderkette und senken die Betriebskosten entscheidend.

Der Abbau erfolgt mit Schaufelradbaggern, Bandanlagen und Absetzern sowie mit konventionellen Kettenbaggern und der zugehörigen Transportflotte aus 6x6-Schwerlast-Dumpern. Diese arbeiten vor allem an den Rändern oder in tiefen Lagen des bis zu 12 Meter dicken Braunkohle-Hauptflöz im Baufeld Süd, wo der Einsatz der Schaufelradtechnologie (Schnitttiefe 4 m) mangels Mächtigkeit der Restschichten unwirtschaftlich wird.

auch große Massen an Abraum, der in Helmstedt in einem Abraum/Kohleverhältnis 3:1 ansteht: insgesamt 8 Millionen Kubikmeter stark heterogenes Material werden jährlich im Tagebau Schöningen durch die Bergbau-Großgeräte und die mobile Flotte abgedeckt und wiederverfüllt.

Die große Ausdehnung des Baufelds und die inzwischen erreichte Abbautiefe von gut 150 Metern stellen höchste Anforderungen gerade an die Schwerlast-Dumper. Im ganzjährigen Zweischicht-Betrieb fahren sie im Wechsel Kohle oder Abraum, wobei die Umlauflängen je nach Material und Standort der 5-m³-Tieflöffelbagger stark variieren. Derzeit liegen die Distanzen bei etwa 1800 Metern (Kohle) bzw. 3500 Metern (Abraum) auf schwerem lehmigen Untergrund mit engen Kehren und mit Steigungen bis 17 %.

Offener WettbewerbDurchschnittlich 2500 Betriebsstunden pro

Jahr erreichen die in Helmstedt eingesetzten Dumper. Mit eigenen Werkstattkapazitäten ist die Abteilung Fahrzeugmanagement im Tagebau Schöningen unter Leiter Joachim Nagel für die tägliche Verfügbarkeit der Transportflotte verantwortlich. Gleiches gilt für die Erneuerung des Fahrzeugbestandes, die im vergangenen Jahr für die insgesamt 18 Vierzig-Tonner nach gut 7.500 Betriebstunden pro Fahrzeug anstand.

E.ON ging die Investitionsentscheidung generalstabsmäßig an: Im offenen Wettbewerb bewarben sich die Topmodelle der führenden Dumper-Hersteller in einem 14-tägigen Dauertest nach spezifisch aufgestellten Kriterien. „Wir erstellten ein Testprogramm, das möglichst genau die typischen Betriebsbedingungen bei uns abbildete“, erklärt Joachim Nagel. „Auf identischen Strecken ermittelten wir die gefahrenen Tonnagen und Kubaturen, verglichen Umlaufzeiten und Treibstoffkonsum per GPS-gestützter Streckenerfassung und bewerteten das Fahrverhalten der einzelnen Modelle in der Praxis. Dabei legten wir besonderen Wert auf die Bremscharakteristik unter Last und die Stabilität der 6x6 beim Abkippen der unterschiedlichen Materialien und auf wechselndem Untergrund, zum Beispiel auch gegen den Hang.“ Im Sinne des modernen TCO-Ansatzes (Total Cost of Ownership) ermittelten die E.ON-Fahrzeugmanager zusätzlich zu den

Leistungs- und Verbrauchsdaten auch laufzeitabhängige Servicekosten und voraussichtliche Maschinen-Restwerte, die gemeinsam mit dem notwendigen Personalaufwand in die langfristige Produktivitäts-Analyse einflossen.

Leistung setzt sich durchÜber seinen regionalen Vertriebspartner Kurt König

Baumaschinen mit der nahe gelegenen Niederlassung Magdeburg schickte Bell Equipment den Bell B50D ins Rennen. Als einziger echter „50-Tonner“ mit einer Nutzlast von 45,4 t besaß das 390 kW starke Bell-Flaggschiff zwar die vermeintlich beste Papierform.

Geladen wird im Tagebau Schöningen mit insgesamt 5 5-m³-Kettenbaggern. 200 mm-Bordwanderhöhung ab Werk und die automatische Heckklappe steigern das Nennvolumen der Bell B50D auf rund 30,5 Kubikmeter (SAE 2:1). Beidseitige „Ladeampeln“ erleichtern das Beladen mit stark variierenden Abraumqualitäten oder in der Kohleförderung.

Konkurrenz mit freigegebenen Nutzlasten bis 39,5 t, musste sich das breitspurige, auf große Reserven ausgelegte Bell-6x6-Konzept im Praxistest jedoch erst beweisen.

„Im Fahrbetrieb hat der Bell B50D vor allem durch seine sehr ausgewogene Charakteristik überzeugt. Antrieb und Verzögerung sind jederzeit präsent und lassen sich stets genau dosieren. Das betrifft vor allem auch den Retarderbetrieb, der bei unseren Fahrzeugen 5 Prozent der Gesamt-Fahrzeit ausmacht, “ fasst Joachim Nagel die Testeindrücke zusammen. Auch bei Transporttonnagen und -kubatur konnte die 28-m³-Standardmulde des Bell B50D punkten: „Die Geometrie der Bell-Mulden passt sehr gut zu den Ladespielen unserer 5-m³-Bagger. Trotz stark wechselnder Abraum-Schüttdichten von 1,5 bis 2,2 t/m³ bringen die Bell dank integrierter ‚Ladeampel’ und ausreichender Toleranz zuverlässig das mögliche Maximum auf die Strecke.“ In der „leichten“ Helmstedter Kohle (Schüttdichte: 0,9 t/m³) zählt freilich auch anderes: Mit rund 34,5 Tonnen Leergewicht wiegt der Bell B50D netto um nur vier bzw. unter zwei Tonnen mehr als der

40-Tonnen-Wettbewerb mit vier bis sechs Kubikmeter Nennvolumen weniger – rein verbrauchstechnisch ein Vorteil bei Leerfahrten, der sich selbst mit großen Bordwand-Erhöhungen nicht auffangen lässt.

„Am Ende lag der Bell B50D in der Produktivität über die von uns veranschlagte Nutzungsdauer von vier Jahren deutlich vorne“, stellt Joachim Nagel fest. „In den laufenden Betriebskosten brachte der Test nur marginale Unterschiede – entscheidend war, dass wir mit nur 15 Neumaschinen und zwei bestehenden Altgeräten die gleiche Leistung gegenüber unserer bisherigen 18er-Flotte oder einem möglichen Ersatz mit den getesteten 40-Tonner erreichen und so künftig ein Fahrzeug einsparen.“

Hohe Verfügbarkeit garantiertNach Auftragsvergabe im Mai 2010 wurden die ersten

Bell B50D ab Anfang Oktober geliefert. Im Februar arbeiteten bereits sieben Fünfzigtonner in Helmstedt,

bis Mitte 2011 treten die restlichen Großdumper ihren Dienst an. Bereits beim deutschen Mulden-Produzenten GFT Gotha wurden die 28-m³-Standardmulden nach strengen Hersteller-Standards mit 200-mm-Muldenerhöhungen versehen, was das SAE-2:1-Nennvolumen gemeinsam mit der automatischen Heckklappe auf rund 30,5 m³ erhöht. Bis zu 30 Tonnen betragen jetzt die Braunkohle-Transportchargen, zuverlässig am Nutzlastlimit fahren die Bell B50D mit grobstückigem Lehm oder stark fließendem sandig-kiesigem Abraum.

die satellitengestützte Bell-Maschinen-überwachung Fleetm@tic. „Wir setzen Fleetm@tic vor allem zur genauen Erfassung der Transportleistungen ein“, erklärt Joachim Nagel. „Aufgeschlüsselt in Tages-, Wochen- oder Monatsberichte können wir damit die Gesamtleistung unserer Förderkette beurteilen und gegebenenfalls optimieren. Durch Zugriff auf maschinenspezifische Ladeprotokolle und hinterlegte Statusmeldungen arbeiten wir gemeinsam

Ein wichtiges Kriterium beim Kaufentscheid waren die guten Kippeigenschaften der Bell B50D. Neben der leistungsfähigen Muldenheizung kommen dabei vor allem die umfangreichen Assistenzfunktionen der Bell-Maschinensteuerung zum Tragen, die den Fahrer bei den Routinevorgängen unterstützen.

mit unseren Fahrern an der Einzel-Performance.“ Auch im Bereich der Wartungsplanung leistet das Online-System Fleetm@tic wertvolle Dienste: fällige Regelwartungen werden gemeldet, im Rahmen der auf 10.000 Betriebsstunden angelegten Bell-Verfügbarkeitsgarantie können die zuständigen Techniker etwaige Fehlfunktionen frühzeitig erkennen.

Grundsätzlich positiv sind die Betriebserfahrungen nach den ersten 1000 Einsatzstunden: „Bereitstellung und Inbetriebnahme verliefen planmäßig, alle Bell-Dumper fügten sich reibungslos in die Betriebsorganisation ein“, urteilt Joachim Nagel. „Unsere Fahrer loben die Bedienungsfreundlichkeit der Fahrzeuge – neben den wirklich überzeugenden Leistungen auf der Strecke, insbesondere auch die sinnvollen Automatik-Funktionen, die Routine-Abläufe beim Laden oder Kippen erleichtern.“ Auch Leistung und Verbrauch stimmen: „Wir haben für Einzelfahrzeuge bereits Transportspitzen von über 2800 Tonnen pro Doppelschicht ermittelt, bei Umlaufdistanzen um 1500 Meter und durchschnittlichen Einzelchargen um 43 Tonnen – bei einem Durchschnittsverbrauch von 23,0 l/h! Selbst bei besonders langen Umläufen unter Maximallast am Berg lag der Konsum lediglich um 40 Liter pro Stunde. Tatsächlich überraschten uns die großen Bell im Betrieb mit niedrigeren Verbrauchswerten als unsere bisherigen 40-Tonner.“

Nach gut 1000 Betriebsstunden ist Joachim Nagel, Leiter Fahrzeugmanage-ment im Tagebau Schöningen, mit den Leis-tungen der Bell B50D hoch zufrieden. Das gilt auch für den Einsatz des Flottenmana-gement Systems Fleetm@tic, das wichtige Schlüsseldaten der Fahrzeuge in leicht auswertbare Protokolle zusammenfasst.

Wichtigen Anteil an der Leistungsfähigkeit der Großdumper hat die er-gonomische Gestaltung des Fahrerarbeitsplatzes. Wichtige Statusmeldungen der Maschinensteuerung sind stets im Blick – alle Funktionen des zentralen Schaltermoduls lassen sich intuitiv bedienen.

Greatly improved traction system The HM300-3 features the new Komatsu Traction

Control System (K-TCS). The K-TCS automatically provides optimum traction when operating in soft ground conditions. As ground conditions worsen and tire slippage is detected by speed sensors located on four wheels, automatic application of the inter-axle differential lock occurs. If tire slippage continues to be detected then four independent brakes can be applied to slipping wheels to regain traction.

The HM300-3 is enhanced with K-ATOMiCS—Komatsu Advanced Transmission with Optimum Modulation Control System. K-ATOMiCS offers a six-speed, fully-automatic transmission that uses an advanced electronic system to eliminate shift shock and torque cutoff to improve operator and power train efficiency. It automatically selects the ideal gear based on vehicle speed, engine rpm and the shift position chosen, which results in a powerful acceleration, smooth down shifting and synchronized engine speed when climbing slopes. This ultimately minimizes operator fatigue, keeps the load in the body and increases productivity.

A large automatic retarder system allows the operator to select the optimum operating speed on downhill travel under full load, allowing a save operation under a wide scope of working conditions.

Increased payloads Through body design optimization, the HM300-3

features increased body capacity and payload. The low 2820mm loading height easily matches with 30-ton to 60-ton hydraulic excavators or 5 yd³ to 7.5 yd³ wheel loaders. In addition, the two single-staged body lift cylinders provide a 70-degee dump angle for easy unloading

Enhanced operator environment The new cab design provides a comfortable and

quiet work environment so operators can maximize their productivity. The ROPS/FOPS Level 2 certified cab features a new rounded front dash panel with easy to reach switches. The new comfortable high back, heated air ride seat with 2 - point seat belt

improves operator comfort and all-round visibility. An auxiliary input was added to connect an MP3 player or other devices along with two 12-volt ports that have been incorporated into the cab.

A new high resolution 7” LCD monitor features enhanced capabilities and displays information in 25 languages for global support. With the monitor, the operator can easily modify settings for items such as the Auto Idle Shutdown or the auto-reversing fan; check operational records, such as driving history or fuel consumption; monitor the KDPF or check the time remaining before the next required maintenance. The monitor also offers the option of using the ECO Guidance function, which provides operational tips to reduce fuel consumption. A separate high resolution back-up camera is standard with every machine and is mounted on the right hand side of the console for operator convenience.

Convenient Maintenance and Serviceability

The HM300-3 provides easy service access to reduce costly downtime. It has a redesigned engine hood with an optimized narrow shape for better visibility, and to allow easy access to all major maintenance points.

The new machine a standard hydraulically driven auto-reversing fan to help keep the radiator and charge air cooler clean –and to further lower fuel consumption.

The machine is equipped with the exclusive Komatsu EMMS (Equipment Management Monitoring System), which has enhanced diagnostic features that give the operator and technicians greater monitoring and troubleshooting capabilities. EMMS also continuously monitors all critical systems, preventative maintenance, and provides troubleshooting assistance to minimize diagnosis and repair time.

STEINExPO 2011 – BAUMASCHINEN-DEMO MIT CATWALK-EFFEKT!

JUNI 2011: STILL VOR SICH HINARBEITEN UND BRAV BESTäNDIGE LEISTUNG ZEIGEN. SO SIEHT EIN NORMALES BAUMASCHINENLEBEN AUS. DIE MODERNE BAUMASCHINEN-DEMONSTRATION AUF MESSEN KANN EBENFALLS SO ABLAUFEN – MUSS SIE ABER NICHT. DASS DIE VORSTELLUNG DER NEUEN MODELLE DURCHAUS EINE PROFESSIONELLE BEGLEITUNG VERTRäGT, BEFANDEN DIE ORGANISATOREN DER STEINExPO GEMEINSAM MIT DEN HERSTELLERFIRMEN. SO WIRD IN DIESEM JAHR ERSTMALS BEI DER STEINBRUCH-DEMONSTRATIONSMESSE IN NIEDER-OFLEIDEN DAS GESCHEHEN IN DER GEMEINSCHAFTSDEMONSTRATION MODERIERT.

Im Einsatz sind auf etwa 22.000 m² des „Messegeländes“ im MHI-Steinbruch Nieder-Ofleiden Baumaschinen zehn verschiedener Hersteller. Die Demonstrationen finden alle 30 min an drei verschiedenen Ladestellen statt, wobei an einer Ladestelle zusätzlich die Rückverladung praxisgerecht demonstriert wird. Während das technische Planungsteam des Institut für Bergbau der TU Clausthal gerade die technischen Abläufe so koordiniert, dass

diese vor den kundigen Augen der Fachleute – die regelmäßig mehr als 90 % der steinexpo-Besucher der ausmachen – bestehen können, entwickeln sich parallel dazu der Showrahmen mit passender Musik und Moderationskonzept. Alle Elemente verschmelzen schließlich zu einer einheitlichen Choreographie. Als Moderator konnte Raoul Helmer gewonnen werden. Bekannt sind dessen Moderationen nicht nur vom hessischen Rundfunk. Helmer hat es darüber hinaus

schon bei diversen Baumaschinen-Einsatzshows verstanden, ganze Zuschauerscharen gleichzeitig bestens zu informieren und gut zu unterhalten. Angespornt durch die positiven Resonanzen aus dieser so rauen und ehrlichen Branche, hat er auch den umfangreichen steinexpo-Auftrag mit Freude übernommen. Der Ablauf ist so geplant, dass der Moderator mit je einem Ausstellervertreter pro Marke im Interviewstil die besonderen Qualitäten der Arbeitsmaschinen hervorhebt und damit die Aufmerksamkeit der Besucher ganz gezielt auf wichtige Features lenkt.

Steinexpo-Messechef Dr. Friedhelm Rese freut sich, den Besuchern ebenso wie den Ausstellern damit wieder eine neue Besonderheit dieser speziellen Messe anbieten zu können: „Ich will nicht sagen, dass die steinexpo mit ihrer 8. Durchführung schon in die Jahre gekommen wäre. Die Messe ist immer noch allein vom Konzept her eine Besonderheit, die speziell Fachbesucher anspricht. Dennoch ist uns die Integration neuer Elemente, mit denen sich die Exponate der Hersteller noch besser in Szene setzen lassen, regelmäßig ein Anliegen. Wo schwere Technik arbeitet, muss Unterhaltungswert nicht ausgeschlossen werden. Ich freue mich, dass wir beides diesmal in so enger Verzahnung anbieten können. Hinzu kommt, dass die Form der Vermittlung

steinexpoAls größte und bedeutendste Steinbruchsdemonstrationsmesse auf dem europäischen Kontinent feierte die steinexpo im September 1990 im Steinbruch Niederofleiden ihre Premiere. Die Messe wird im Drei-Jahres-Turnus durchgeführt. Im Rahmen eindrucksvoller Live-Vorführungen vor der Kulisse eines beeindruckenden Steinbruchs zeigen Hersteller und Händler von Bau- und Arbeitsmaschinen, von Nutzfahrzeugen und Skw sowie von Anlagen zur Rohstoffgewinnung und -aufbereitung ihre Leistungsfähigkeit. Einen weiteren Schwerpunkt der Messe bildet das Recycling mineralischer Baustoffe. Veranstaltet wird die steinexpo von der Geoplan GmbH, Iffezheim.

natürlich auch andere Hersteller anspornen wird, etwas Besonderes auf die Beine zu stellen, um in der Besuchergunst zu punkten. Dieser Effekt kommt letztlich allen Ausstellern und der gesamten Messe zugute.“

Das Messegeschehen der steinexpo 2011 wird darüber hinaus erstmalig auch im Web-TV zu sehen sein. Als offizieller Medienpartner berichtet Bauforum24 TV jeden Tag über Neuheiten, Meinungen und Produkte direkt vom Messegelände. Im Messestudio werden die Sendungen mit Interviews und Berichten über neue Produkte und Branchennews direkt vor Ort produziert. Alle Sendungen sind wie gewohnt rund um die Uhr auf www.bauforum24.tv zu sehen. Für Smartphone Nutzer stehen sie auch unterwegs als Podcast für iPhone, Blackberry und Co. zur Verfügung.
