ForewordSince the introduction of our first railbound pneumatic shovel loader in the 1930s, we have been providing our customers with underground loading and haulage equipment. In our product development, our target has always been to improve productiv-ity, reliability, ergonomics, service friendliness, and not the least, safety!

Railbound machines, as the first step of mechanization, improved productivity in mines tremendously. However, railbound equip-ment has limitations in terms of flexibility. This resulted in the development of rubber-tyred pneumatic LHD loaders, starting with the T4G in 1956, and followed by the Cavo 310 and 511 four-wheel drive versions. These vehicles eliminated the problem of tracklaying, but were still limited in mobility due to their need for compressed air.

The next milestone was the introduction of the first Scooptram, the ST5. This vehicle was developed by Eddie Wagner, and was the first diesel-driven Load Haul Dump loader for underground mining. Eddie’s brother Elmer had earlier invented the 4-wheel drive articulated vehicle in 1949. Scooptram loaders have, since their introduction into the mines in 1963, been recognized for their flexibility, high productivity and low cost of operation.

The real breakthrough for Scooptram loaders came during the 1970s after the introduction of hydraulic rock drilling. The com-bination of hydraulic drill rigs and LHDs became a flexible and competitive package for underground mining operations. The newly-invented Robbins raise drill also offered an efficient alter-native for improving ventilation systems in mines when changing from pneumatics to diesel and electro/hydraulic power.

In 2003, for reasons of synergy, we decided to move production of Scooptram and Minetruck products from Oregon in US to our drill rig manufacturing plant in Orebro in Sweden. We knew what had to be achieved and, within a very tight schedule, the new assembly hall was designed and built, the engineering facil-ity re-established, and the production lines set up and manned.

An aggressive new product development plan was established based on thorough market surveys, interviews of numerous operators, service people and mine management in the major mining countries. The first result is the 14 t loader Scooptram ST14. With an efficient load sensing hydraulic system, a modern accurate control system and a cab with “Business Class” ergo-nomics, it has received acclaim as the most productive loader in its class. It is designed to meet the most stringent requirements of the international mining and tunnelling industries. Not only is it fast and comfortable to drive, it is also highly productive and easy to maintain.

The Rig Control System featured on the Scooptram ST14 is a common automation platform for nearly every type of machine produced at Orebro, eliminating hydraulics from the cabin, reducing electrical connections, facilitating fault finding, record-ing and displaying data, and offering the option of radio remote control. Easy access for quick maintenance is also an important feature.

All loaders and trucks in our product range have been upgraded, mainly to improve reliability and serviceability. The most obvi-ous examples are the Scooptram ST1030 and the Minetruck MT2010 which have been equipped with the new Cummins QSL 9 diesel engine. It is a modern clean burning, fuel efficient engine that meets the US EPA Tier 3 and the European stage 3A emissions regulations. Also, we have added low profile loaders to our portfolio, like the ST1030LP and ST1520LP.

Our optimism for the future leads us to publish this book, in which we describe our products, their applications, and their specifications. We hope the mix of technical papers, case studies, and vehicle descriptions is to your liking, and will help you to select the right equipment for your application.

Of one thing you can be sure: we will continue to be driven by innovation and a solid commitment to providing first class service.

lhD machines in mines

Mechanization of underground produc-tion and development has led to increas-ing use of LHD equipment, because of their success in the particularly harsh mining environment. Not only are their dimensions favourable to underground operations, but LHDs have also demon-strated capability for climbing steep gradients, and for moving quickly over long distances. LHD technology has continuously improved productivity under all mining conditions, from small and narrow orebodies to the largest of open stopes, and in low headroom and difficult entries. In essence, LHDs are semi-rigid, low profile loaders with large bucket volumes that give high mucking capacities in limited spaces. They are especially good in mining applications, with their combination of capacity, manoeuvrability and speed.

Diesel powered LHDs are versatile and flexible, and find a variety of uses in

mining, apart from their normal work on production and development. They may be used for road cleaning, material haulage, or loading trucks.

When loading between stope and orepass, the haulage distance is usually between 50 m and 400 m, whereas less than 100 m tramming is normal when loading trucks.

All in all, LHDs feature around 50% higher payloads compared to front end loaders with the same engine size, and their long wheelbase gives better sta-bility and higher tramming speeds car- rying a full load.

Dimensions

Regulations for vehicles working under-ground usually focus on minimum wor- king clearances and ventilation require-ments, which will limit the choice of size of unit and its horsepower setting, and possibly decide between diesel and

electric power. Trends in mine design are to accommodate the most-productive equipment possible, because operating costs have been shown not to be directly proportional with increased capacity. Also, the cost of labour is significant, no matter the location, and this may favour larger machines. Nevertheless, there are physical and financial limitations on the size of openings underground, so the fit of the machine becomes a major consideration.

In mine operations, the clearance between vehicle and sidewalls, and ope- rator and roof, are critical factors, which will help decide the model best-suited to the conditions. A rule of thumb is to allow a total of one metre minimum operating clearance between vehicle and sidewalls. Sometimes, when a mine is mechanizing using trackless vehicles, the enhanced productivity may allow for enlargement of openings. More often than not, the vehicle has to fit the

Matching the Scooptram to the jobOriginal and bestFor nearly 50 years, Scooptram loaders have been recognized for reliability, power and low cost of operation. Since the first LHD was introduced into the mines in 1958, development has been continu-ous, resulting in the current range of Scooptram loaders, designed to satisfy all production require-ments at low cost/tonne. In each succeeding generation, design improvements are added, build-ing upon established model strengths. Now that Scooptram loaders are built in the Atlas Copco plant at Örebro, Sweden, the pool of available engineering expertise has grown consider- ably, reflected in recent announ-cements of all-new models such as the Scooptram ST14 loader. These next generation loaders are being added to the current range of basic models plus vari-ants designed to satisfy the most stringent requirements of the international mining and tunnel-ling industries.

existing openings, and the model will be chosen on the basis of the highest productivity achievable given these con- straints.

Bucket capacity

Selection of Scooptram bucket size will be governed by the density of the mate-rial to be moved. Rock may swell by as much 60% when blasted, and its loose weight/cu m has to be established before recommendations can be made about bucket size. Likewise, abrasivity of the mineral will affect the choice of wear parts for the bucket. The bucket rated capacity will normally be quoted by reference to heaped capacity, but average fill achieved will depend on other factors, such as driver expertise, blasting fragmentation, roadway condi-tion, and route alignment.

Atlas Copco establishes a rated tram- ming capacity for each of its Scooptram loader models, which is the gross recom- mended payload. They then calculate the standard bucket size, based on mate-rial weighing 2.0 or 2.2 t/cu m. If the material to be moved is heavier than this, a smaller bucket may be fitted. If the material is lighter, a larger bucket

may be recommended to take full ad-vantage of the rated tramming capacity. Engine, torque converter and transmis-sion are matched and approved for each model, along with axle and tyre capa-cities. The engineers then consider the overall quality and strength of their de- sign against the envisaged working cycle and projected life. This will result in a qualified statement of rated capacity.

Payload should be as close as possible to the rated tramming capacity for the selected model, and overloading should be avoided. Consistent overloading, while apparently attractive, will result in excessive tyre wear, higher operat-ing costs, and shorter working life for the vehicle. Different size buckets are available in increments of 0.2 t/cu m to suit the broken density of the rock to be loaded.

One-pass loading

Optimized one-pass loading is a major contributor to overall productivity, and Atlas Copco has devoted much time and resources to perfecting this technique. These new design features have been incorporated into the latest models of Scooptram loader, such as: the high-shape,

high-angle bucket; the Z-bar bucket linkage for higher breakout force; and a higher power-to-weight ratio, with fully-integrated drivetrain, for better tractive effort. As a result, the attack on the muckpile is a more controlled event, with power directed to the bucket edge, instead of being wasted in wheel spinning.

The breakout force in the muckpile is a combination of mechanical force pro- vided by the weight and forward move-ment of the Scooptram and hydraulic force provided by skilful movement of the bucket and boom by the operator. To reduce bucket loading time, powerful hydraulics are required with both tilt and lift functions operating simultaneously. These have to react against the load frame, thereby distributing the stresses throughout the frame. Better visibility for the operator allows for more efficient loading, resulting in less stress trans- ferred to the frame. For consistent one pass loading under all conditions, joy- stick operation and sensitive controls are a basic requirement. For the trip to the discharge point, the narrow dimen- sions of the Scooptram loader, and its 85 degree turning angle, ensure that time saved on loading is not wasted when

tramming. One pass loading, safe tram- ming, and efficient dumping, turning and accelerating, will result in the best possible cycle time. For loading into a Minetruck, the norm is to ensure that the truck is filled in 3-4 passes.

Breakout force

As there is no commonly accepted norm for measuring the breakout force of LHD loaders, it is usual to apply the figures defined for surface loaders. Both SAE and ISO norms are available for surface loaders, and give roughly the same break- out force.

Breakout force is expressed in two different ways, as hydraulic breakout force, and as static vehicle breakout force, which is also called static tipping capac-ity, SAE J732.

The Society of Automotive Engineers (SAE) defines hydraulic breakout force as the maximum sustained vertical up- ward force exerted 100 mm (4 in) behind the tip of the bucket cutting edge, and is achieved through the ability to lift and/or roll back the bucket about a pivot point. It is measured with the pivot point supported, and the vehicle anchored to avoid any movement.

The static vehicle breakout force is the minimum amount of hydraulic break- out force that will rotate the vehicle about the front axle, lifting the rear wheels clear of the ground. It is measured while the vehicle’s brakes are off, and with its transmission in neutral.

The difference between these two types of breakout force is important in assessing the design productivity of the vehicle, because not all of the hydrau-lic breakout force can be utilized if it causes the rear wheels to leave the ground.

Most manufacturers of LHD loaders use the bucket tilt circuit to maximize the hydraulic breakout force. However, the standard does not determine the dis-tance of the measuring point from the bucket pivot point, so the breakout force can be varied with the same loader when operating the bucket circuit, simply by using different types or sizes of bucket. This can result in confusion, so compar-isons should only be made of machines with similar buckets in which the depth of the cutting edge or bucket volume is the same.

In a powerful loader making the best use of its hydraulics, the breakout force using the lift circuit should be sufficient

to raise the rear of the machine off the ground, while the hydraulic breakout force using the lift circuit with the rear of the machine anchored should exceed the force obtained using the bucket tilt circuit.

load sensing hydraulics

Whenever a loader attacks a rock pile underground, a tremendous amount of power is required to thrust the bucket deep enough so that it can be filled to capacity. Wheels spin, buckets get stuck and the vehicle often has to make se- veral attempts before successfully pene- trating the muck. Sometimes, the driver has to be content to pull away with only a partial bucket load.

In the same way, LHDs that have to tackle steep, uphill gradients need extra power to maintain sufficient speed to ensure that the load will reach its desti- nation within the projected cycle time. The latest Scooptram ST14 is fitted with a modern Load Sensing Hydraulic Sy- stem, which is well-proven and reliable. For more information about the this sy- stem, please see page 19 and the article Efficient Underground Loading and Haulage.

A full bucket is the objective of every trip to the muckpile.

Safety and controlCreating a safe and comfortable envi-ronment for drivers is now, more than ever, a top priority. The Scooptram loader driver is side-seated, for bi-direc-tional operation and maximum visibility. Every Scooptram is fitted with an ope- rator’s cabin or canopy, certified to meet current regulations, including ROPS/FOPS, EC and MSHA. They feature a comfortable seat with plenty of legroom, and correct ergonomic posi- tioning, designed to reduce driver fati-gue and create a much-improved safety environment. The cabins are proofed against sound and vibration, and wider windows give the driver improved vis-ibility, enhanced by well-placed, high-intensity lights.

Improving driver control is always high on the list of priorities. Scooptrams have: automatic gear selection which matches the correct gear to the operat-ing load; a two-handed electric control system, which allows the driver to focus on loading and tramming, rather than on gear changing; forward, reverse, and

neutral buttons on the hoist and dump controls; and the SAHR braking system, considered to be the safest available.

low operating costs

Reducing maintenance cost and time contributes to a lower cost of ownership and higher productivity. Atlas Copco has designed low maintenance into its Scooptram loaders, with fewer wear parts, improved durability of spares, and components that are mutch easier to maintain.

The trunnion caps retention assem-bly makes pin replacement faster and easier when changing cylinders and buckets. The electronically controlled transverter is fully integrated with the engine in a matched powertrain that delivers longer lifespan.

A tapered roller bearing articula-tion hinge offers more than 10,000 h service. Hydraulic manifolds replace piping wherever possible, and hydrau-lic pumps are mounted above the transverter for easy access and quick maintenance.

The economical working life of an LHD is decided when the graph of total costs, including depreciation and main- tenance, rises above an acceptable level. As a machine gets older, it’s capital costs reduce and its maintenance costs rise. Selecting the correct model will result in optimum capital costs, while en-gineering design and regular servicing will help control the maintenance costs, resulting in a long working life and a lower cost/tonne.

Operator first - latest Scooptram ST14Based on the principle that job satisfac-tion has a significant impact on produc-tivity, in designing the next generation Scooptram series of loaders, Atlas Copco has put operator safety, comfort and working environment first.

The new Scooptram ST14 loader pro- vides excellent visibility from the cab, due to a combination of large wind-screens, a clean, flat top to the vehicle, and a short and low-level rear end. The driving seat is air-suspended and softer

and more comfortable than in other LHDs, with the controls located in the armrests. The drive train design has cre- ated more free space in front of the cab, accommodating a unique, roomy foot-box into which the driver can stretch out his legs.

When driving the ST14, the operator is conscious of a spacious and clean en- vironment in the cab, and the long wheel- base makes for a smooth ride. The ride control system allows the loaded vehicle to be driven at high speed while still retaining maximum comfort.

Effective climate control, and the absence of hydraulic hoses in the cab, also contribute to a good environment, both in terms of temperature and air quality, and to safety.

The ST14 aims to prove the concept that an investment in an exceptionally good working environment is an invest-ment in increased productivity.

Versatile and productive - Scooptram ST710One of the most versatile 6.5 t LHDs on the market today, the Scooptram ST710 is packed full of productivity enhanc-ing features. Compared with other 6.5 t loaders, the ST710 wins hands down, with the highest bucket lift and longest reach. It also makes claim to one of the fastest tramming speeds for loaders in its class.

The narrow 2.14 m width of the ST710 allows it to work in drift sizes down to 2.9 m-wide x 3.7 m-high. Available with a choice of two 6-cylinder water-cooled engines, the 200 hp (149 kW) Deutz Diesel and optional 210 hp (157 kW) Detroit Diesel, the versatile ST710 is a highly productive performer. Matched with a Minetruck MT2010 and Boomer 281 drill rig, the Scooptram ST710 can provide the centrepiece of an unbeatable team for medium-section tunnelling.

Productivity with comfort - Scooptram ST1030The new 10 t-capacity loader from Atlas Copco, the Scooptram ST1030, carries forward a long legacy of high produc-tivity in this payload category. Building upon the strengths of the popular ST1020,

TAlking TeChniCAlly

the ST1030 incorporates numerous design improvements and customer suggestions, including the new ergonomically designed operator’s cabin offering reduce fat- igue and better safety, and easy ser- viceability of the split-cap pins and hydraulic system.

With a Cummins QSL 9, Tier 3 diesel engine rated at 250 hp (186 kW) and transmission, and mono-stick controlled articulated hydraulic power steering, the ST1030 makes driving a pleasure. Add to this the excellent breakout force, and a 25 km/h tramming speed on the flat, and the ST1030 becomes one of the most productive LHDs available for working in drift sections down to 3.3 m- wide x 3.9 m-high.

Big payload - Scooptram ST1520Designed for size, strength and ease of operation, the Scooptram ST1520 achieves the highest productivity for any loader in its class. This 15 t-capacity loader provides su- perb visibility from the ergonomically designed and safe operator’s cabin. Equip- ped with a 400 hp (299 kW) 6-cylinder water-cooled Detroit Diesel engine, its rugged structure makes it a champion

performer, both in the muck pile and in tramming over long distances. Constructed upon the same prin- ciples as the ST710 and ST1030, the ST1520 includes all the innovation and improvements from these models, ma- king it an unparalleled production per-former in drifts down to 4 m-wide x 5 m- high.

SummaryThe wealth of experience gained by Scooptram loader designers over the last half century is put at the disposal of the purchaser. This ensures that all operational considerations are taken into account in their recommendations for the correct vehicle for the job.

Standard features

The model range covers capacities from 20 to 50 metric tonnes, with options for different material densities. All the Minetruck products can be fitted with Ansul fire suppression, Lincoln auto lube and Wiggins fast fuel fill, in addition to a comprehensive range of options. The Minetruck MT2010 is covered in detail later in this edition, while the three larger members of its family are de-scribed below.

All Minetruck versions feature ROPS/ FOPS canopy with back protection; auto- matic engine overspeed protection, and reduced heat from braking; electric trans- mission shift control for convenient shif-ting; converter lockup for better power transfer, less heat and longer component life; centralized lubrication to simplify maintenance; and SAHR brake system for reliable braking.

The productivity of trucks is measured by the tonnage carried per km/hour. The cost/tonne of moving the material is then derived from this figure.

Minetruck MT431B

The MT431B is a 28.1 t-capacity truck for large underground operations in mining and construction. Its dump box

can be emptied in 14 seconds. It is mat-ched to Scooptram loaders ST1030 and ST14. It is powered by a Detroit Diesel DDEC Series 60 engine with a rating at 2,100 rev/min of 298 kW/400 hp. It has a Spicer 6000 Series transmission with full power shift on 4 speed forward and reverse through a single stage Spicer CL-8000 series torque converter with lockup to Rock Tough 508 axles. SAHR braking with fully-enclosed, force-cooled multiple wet discs at each wheel end offers long component life and reliable braking. The operator is side seated in a Grammer seat with retractable seat belts for bi-directional driving, using two pilot operated joysticks for steering and dump control, and is protected by a canopy that is MSHA-ISO ROPS/FOPS approved.

The MT 431B has a top speed on the level of 24.8 km/h empty and 22.8 km/h loaded.It has a fuel tank capacity of 439 litres, with a fuel consumption at

full load of 35.5 litres/h. It has a height of 2.74 m to the canopy roof, a width of 2.795 m, a length of 10.18 m, and a turning angle of 42.5 degrees. It will operate in galleries of 5.5 m-width with chamfered corners.

Minetruck MT436B

The Minetruck MT436B has a similar specification to the MT431B, with a wider body and larger 32.6 t-capacity. The MT436B has a height of 2.68 m to the canopy roof, a width of 3.065 m, a length of 10.18 m, and a turning angle of 42.5 degrees. It will operate in galleries of 4.54 m-width with chamfered corners, and is matched to Scooptram loaders ST1030 and ST14.

optimum profile for clean and fast dum-ping offering unparalleled productivity in demanding underground operations. It is matched to Scooptram ST1520 for loading.

Power is provided by a Cummins QSK19-C650 485 kW/650 hp clean bur-ning diesel engine. The unique power train includes an upbox and a combined transmission and converter which, along with the engine control system, offers smooth and precise shifting. The MT5010 has all-wheel drive through conventional front and rear differentials and Spicer 53R300 series axles with centre-flange hubs and wheels to match its capacity.

It has an ergonomically-designed, for- ward seating, sound-proofed, air-con-ditioned cabin in which the operator also benefits from a functional instru-mentation layout with monitoring of the hydraulic and lubrication systems. A rear view camera improves the operator’s vision when reversing.

Component access is first class, and the filters are centralized in an easily reachable area. Fuel tank capacity is 644 litres, with a dieseline consumption at full load of 57 litres/h. Fuel tank access covers are readily removed, and point-to-point wiring improves testing and fault location. The dimensions of the MT5010 are 3.2 m-wide, 3.15 m-high to the top of the dump box, and 11.22 m-long. It will operate in galleries of 5.01 m-width with chamfered corners.

Scooptram loadingThe general rule for filling the Minetruck using a Scooptram is that the loader should complete the operation in three or four clean passes. The Scooptram bucket volume may be changed to achieve this ratio in order to maximize the truck load.

For end loading, the bucket width should be 150 mm narrower than the

inside dimension of the truck box, and for side loading, the top of the bucket should extend no more than 400-500 mm below the box side in the dump position. The bucket lip should reach to the cen-treline of the box for perfect loading.

Eject-O-Dump buckets are available for use where ground conditions do not permit adequate back height for Scoop-tram side loading. Using this system, the bucket pin height should be able to clear the box side.

Eject-O-Dump buckets reduce the Scooptram capacity by 10-15%, and this should be taken into account when se- lecting the most suitable Minetruck.

Main objectives

Atlas Copco first introduced four-wheel drive mine trucks in 1960, when the MT10 was built for use in underground mines. In 1985, the MT420 was intro-duced, and 94 units were sold by 2002. The MT420B was manufactured in par-allel in 1998-1999, and 16 units were produced. Its successor, the MT2000, has added another 94 units to this large fleet. Now, the MT2010 takes the place of the MT2000.

The design philosophy for the MT2010 has been to increase productivity and decrease operating cost, resulting in a lower cost/tonne for the customer. It has therefore been designed to improve ser-viceability and to reach higher levels of availability and reliability.

Many of the changes to the MT2010 are similar to those on the recently up- graded Scooptram ST1030 loader, which has also been the subject of redesigned electrics. The two vehicles have the same new instrument panel with built-in data collection unit. The panel features an integrated warning system and an engine fault code display. The system also indi-cates when it is time to change the air filters. The PLC has been moved into the cabin for better protection from the working environment.

The MT2010 has been designed with special attention to driver comfort, with ergonomic seat, extended legroom, and responsive mono-stick steering, which requires very little effort, reduces fatigue, and helps productivity.

new engineThe Cummins QSL 9 diesel engine fit- ted to the MT2010 is clean burning, and meets the US EPA Tier 3 and the Euro-pean stage 3A emissions regulations.

increased productivityAtlas Copco recently upgraded the popular Minetruck MT2000 to MT2010 with a change of engine and redesigned electrical system. Other minor revisions have been incorporated, and the whole con-cept mine tested under rigorous conditions for 2,500 hours in Tur- key. The customer reported that the trial went very well, with good performance, easier maintenance, and excellent operator acceptabil-ity. Absolutely no technical issues needed to be addressed, and the general feedback indicated that the truck is seen as very powerful and comfortable to drive.

The QSL 9 was first delivered with the Scooptram ST1030 for six months. The reports from the customers were posi-tive and the engine was selected for the MT2010 as well.

The fully electronically controlled Cummins QSL 9 has a high-density power design with an electrical sensor for air intake restriction. The alternator is solid mounted to the engine, with a multi rib belt with spring-operated ten- sioner. The transmission cooler has been incorporated into the radiator for better cooling capacity and easier access, and the engine benefits from electronic pro-tection for overheat or low oil pressure. Diagnostic software is available.

The Cummins QSL 9 C300 is an 8.9 litre in-line six-cylinder engine that weighs just 738 kg and is rated as 224 kW/300 hp power output. Its overall di- mensions are smaller than its prede-cessor in the MT2000.

The engine has a high-pressure com-mon rail fuel system with electronic in-jection and a wastegate turbocharger. Users can expect a longer working life due to the lower piston speed, while the

bypass oil filtration in combination with full flow will increase bearing and ring life. All of this adds up to a smoother running engine with lower maintenance and overhaul costs.

Drivetrain and options

The MT2010 has an oversized Clark 5000 series transmission for long life, and converter lock-up to transmit more power to the ground with less heat build-up.

The SAHR brakes are fully enclosed, force cooled, with multiple wet discs at each wheel end. Benefits are a 10,000 h life without adjustment, and increased vehicle safety from what is the safest brake in the mining industry.

The tapered roller bearing articula-tion hinge on the MT2010 also has a 10,000 h life without adjustment.

The Rock Tough axles have a 4,000 h warranty as the best in the industry, with SAHR brakes as an integral part of their design. Conventional differen-tials are standard in both front and rear axles. Lincoln automatic lubrication and

Ansul fire protection can be fitted, and the vehicle can be specified with an ejec- tor box.

The Minetruck MT2010 is purpose matched with the Scooptram 710 and 1030 as efficient loading and hauling combinations.

exercising CARe

Using CARE For Mining, the vehicle needs for the whole mine can be evalu-ated. Simulation using a mathematical model of the proposed system to deal with stochastic variables is far more ac- curate than the traditional spreadsheet. Individual vehicles behave indepen-dently of each other in terms of avail-ability and shift schedules, but, in real life, queues and traffic disturbance in- teract to cause dependence on each other. Simulation allows the engineers to evaluate this behaviour over time, and under different conditions, show-ing the interaction between various ele- ments and how they affect system per-formance. Vehicles of different types and capacities can be inserted into the CARE simulation, together with several production locations. It will handle both truck and loader estimations, and takes different scenarios and varying traffic conditions into account.

Studies have been undertaken at vari-ous mine locations in order to broaden the database, and some of the results are examined in this article.

CARE For Mining simulations are designed for use in all underground loa- ding and transport situations, and will

supply the mine management with vital inputs to their equipment purchase deci-sions.

To summarize, the tool will simulate loading and transport of ore and waste for any hard rock underground mine, and will determine truck and loader needs for different scenarios taking into account the effects of traffic disturbance, availability and preventive maintenance. The best setup can be estimated in a given scenario based on costs, vehicle types, availability, rock properties, pro- duction plan and shift schedules. In ad- dition, different mine layouts can be investigated with respect to productivity.

Simulation as a tool

The CARE For Mining simulation tech-nique is based on trial and error, testing a given scenario for success. A scenario is set up, the simulation is run, the result is analysed, and then the process is rerun with new data, if necessary.

Conventional wisdom is to concen-trate on the problem, not on the data available. Reality can be simplified. If an easy model is chosen initially, and more logic is added when the easy logic generates some results, the objective will be achieved more rationally. Simulation is simply a mathematical model of a real or proposed process or system, in

which objects behave more like real life. This is not possible using Excel calculations because too many input parameters are not deterministic, slack time phenomena are hard to assess, traffic congestion is non-linear by nature, and randomness is hard to simulate.

Hence, for complex processes such as loading and transport logistics within a limited capacity system where parts interact with each other, simulation is necessary.

In underground mines, there are al-ways special considerations, and these include: how to set up when the last loading point is a conveyor belt; how to set up loading from a loading bay only, without any stope or face; how to set up truck needs only, without any loaders affecting the result; and how to set up for chute loading.

Vazante mine study

A simulation of loading and transport requirements was undertaken at Vazante mine, part of the Votorantim Metals group, in November, 2006. The purpose was to estimate the vehicle requirement for replacement of the mine truck and loader fleet. Capacity simulation of loading and transport of ore and waste rock in the mine was undertaken, with-out costs calculations.

Matching the fleet to the jobIn these days of instant cost ana- lysis, it is increasingly difficult to disguise low productivity. The em- phasis on unit costs, in particular, focuses on the performance of the main production fleet. As capital equipment becomes more reliable, its productivity increases. How- ever, productivity is a function of utilization, making it essential that the fleet strength is closely mat- ched to the job. Numbers and ca- pacities of trucks and loaders are key to this, and the Atlas Copco CARE For Mining simulation tool provides the mine operator with a reliable means of estimating this requirement.

The current situation was set up using mine data for January to October, and then adjusted to give results similar to real life. Because vehicles were report-edly overloaded in normal operation, their rated capacity was increased for the purposes of calculation, and a fill factor was not used.

The input data from the first simu-lation was applied to simulate replace-ment with Atlas Copco loaders and trucks, using information supplied by Atlas Copco.

The results from the second simula-tion were then analysed, and equipment input data was progressively refined until the output data reflected the customer’s production needs. Mechanical availabil-ity was used, rather than calendar-based availability. Production over the period was 1,174,062 t using nine trucks of vari- ous designations, for which total hauled, total hours, tonnes/h, and real tonnage were entered into the simulation.

Conclusions

Operational parameters dictate that the mine would need two of the MT5010 trucks to be equipped with teletram boxes, and only 80% mechanical avail- ability is proposed for all trucks. This results in a simulation where four MT5010s are not enough for the required production, whereas five MT5010s will fulfil existing production needs, with some spare time as margin.

Three loaders are enough, because idle time is available for them to in-crease production a little.

The simulation results are estima-tions only, as a guide to choosing the right equipment. The results are based on input data given from the mine.

Common automation platformRig Control System (RCS), which is based on standard PC-computer tech-nology, is the automation platform for Atlas Copco equipment.

CAN-bus technology provides the backbone of RCS. This system is flexi-ble and easily expandable, allowing new units to be added anywhere along the data bus, without adding another cable. The electronic modules are all developed for purpose, and are ruggedized and pro- tected from external magnetic and elec-tric influences.

The third generation of RCS has taken a quantum leap forward with respect to logging capabilities, serviceability and machine accuracy. The flexibility of the system can be adapted and configured for all different types of products. Cus- tomers can start at a low level of auto- mation and, as their requirements change, can upgrade. New functionality can be

added, without major rebuilding of the machine.

RCS benefits

RCS is the Atlas Copco CMT electronic control system platform. It offers increa- sed serviceability, an improved manma- chine interface with options for easy up- grades such as to Radio Remote Control RRC, and comprehensive logging of ma- chine functions. Data is easily collected and transferred using a USB memory stick as standard, or other retrieval means as required.

With RCS, it has become much easier to get information from the machine for servicing and diagnostics, all of which is logged and displayed in clear text on the cabin screen. All of this information is displayed in one place, and there are no hydraulics inside the cabin, redu-cing noise levels considerably. All parts

of the control system are strategically placed to make replacement easy.

Screen display

RCS facilitates improved operator ergo-nomics, clearing the cabin of gauges and instruments, creating more room and bet- ter visibility.

In the main menu, the operator can change the screen display to one of a selection of languages in seconds, allo-wing engineers and operators of several nationalities to operate and service the machine without ambiguity. All menus are self-explanatory, and the screen sym- bols are easily recognizable, so there is no need to interpret the information.

There are several access levels to RCS to prevent accidental or unauthorized changing of parameters and settings. These are restricted at the first level to the operator, then to the local service

Rig Control System for Scooptram loadersQuantum leapThe introduction of the well-proven Atlas Copco Rig Control System RCS to Scooptram loaders has brought seamless integration with the drivetrain components. At the same time, joysticks in armrests, and easy-to-read multifunction colour displays on a single screen, have transformed the operator’s life. The same screen allows main- tenance engineers to check sta-tus on modules and I/O ports, spe- eding fault detection and remedy. With RCS, soft stopped steering reduces vibration, and boom and bucket movements are better con- trolled, all contributing to less stress on operator and machine. A reduced number of electrical con-nection points, richer functional-ity, and component commonality with other Atlas Copco machines all add lustre to the performance of the new generation Scooptram loaders with RCS.

The Scooptram ST14 proves its superior performance in the muck pile.

staff, and at the third level to Atlas Copco service engineers. As a result, nuisance site visits to restore settings are elimi-nated, while fault finding and correction is vastly improved. The RCS screen pro- vides instantaneous monitoring of ope- rational condition for items such as

torque, intercooler temperature, fuel con- sumption, and engine status. The digital dashboard shows warnings and stops on screen, and is completely integrated with the RCS system. If the icon has a green background, there is no error; if yellow, there is a minor error such as

blocked filter; if red, there is a major error such as low oil pressure, and the machine is automatically shut down. A self-diagnostic system makes fault find-ing easy, indicating if there is a module failure, and where the problem lies.

RCS for Scooptram

The new generation Scooptram loaders from Atlas Copco are assembled on an RCS platform, which makes them easier to build and maintain. With all-elec-tronic control, they are automation ready, with much richer functionality and better ergonomy.

It is easier to add options, and all ma- chines are ready for RRC Radio Remote Control as standard. Previously, adding RRC to a machine required the fitting of a heavy electro-hydraulic manifold block to which pilot hoses to the con-trolled functions had to be connected. Then the RRC machine unit had to be installed, and the connections to the manifold block and machine electrical

system had to be interfaced. Thanks to RCS, the current RRC installation is a small MU that fits beneath the seat. Connect power, CAN and antenna, and it is ready for operation!

Other benefits accrue, such as steer-ing interlock, redundant design, and new access control, all of which make for greater safety. Likewise, load weighing, soft stops, logging and services inter-face contribute to functionality.

The first generation of LHDs has me- chanical control linkages. Second gen-eration has pilot hydraulic controls and valves, electronic PLC and extra elec-tronic valves for Radio Remote Control. The current third generation has RCS architecture, CAN-bus based distribu-ted control system, and electronically controlled valves replacing the pilot hy- draulics.

As a result, the number of electrical connection points has decreased by two thirds, reducing the potential for break-down, and making fault detection easier. There is also an interactive user inter-face, and a common RCS platform with drill rigs and other Atlas Copco surface and underground equipment. Hardware and software is developed and main- tained by Atlas Copco Automation Department in Orebro, Sweden.

Current generationThe RCS prototype Scooptram ST1010 C was field-tested at a Canadian mine for 4,400 hours during 2003-2004. The experience has been absorbed into the design of the latest model, the Scooptram ST14 launched in 2006.

The ST14 is joystick controlled from a panel in the armrest. The left joystick steers right and left, with a soft stop. A steering interlock operates when the door is open, or the armrest is not in po- sition. The right joystick controls boom and bucket for hoist and dump.

The transmission selects gears in two major modes: automatic, in which the operator chooses direction and range with dedicated buttons; and semi-automatic in which the operator moves gear ranges up and down as required. There is a ma- nual mode, which is used solely for veri- fication testing. There are brake and throttle pedals set into the unique foot- box, developed for this purpose. Logs are recorded for vehicle statistics over its entire life. The event log covers the last 500 events, such as errors, warnings, and restarts. The maintenance log shows essential pressures and temperatures when limits are exceeded since the last power on. Load weighing is integrated

using hydraulic hoist pressures, and the automatic counting scheme accumulates loads by counting buckets. The accu-racy is +/-500 kg.

iReDeS

In order to facilitate use of different equip- ment from different producers in the same organization, Atlas Copco, together with other major machine manufacturers, mi- ning and construction companies and third party suppliers, has established a standard for data exchange between rock excavation equipment and users’ computer systems. This International Rock Excavation Equipment Data Ex- change Standard, or IREDES, is the common language in data exchange for mining and tunnelling, and the current range of Atlas Copco equipment has been adapted to IREDES.

The Scooptram ST14, for instance, exports production data logs in IREDES XML format.

key source

Whenever a loader attacks a rock pile underground, a tremendous amount of power is required to thrust the bucket deep enough so that it can be filled to capacity. Wheels spin, buckets get stuck, and the vehicle often has to make several attempts before successfully penetrat-ing the muck. Sometimes, the driver has to be content to pull away with only a partial bucket load.

In the same way, LHDs that have to tackle steep, uphill gradients need extra power to maintain sufficient traction to ensure that the load will reach its desti-nation within the projected cycle time.

The key source of power for thrust, bucket movement and traction does not lie in the size of the diesel engine, but in the hydraulic pumping system that distributes and controls the flow of hy- draulic oil. This is where the power for all these critical functions is generated, and where power losses can occur. Cur-rently, there are two systems available. These are the Open Centre and Load

Sensing Hydraulic Systems, discussed below.

Open Centre hydraulic SystemWith the Open Centre Hydraulic Sy- stem, the pump constantly delivers a flow that is proportional to the speed of the engine. When no function is acti- vated, the oil flows through the “open centre” in the valve spools, and is re-turned to the hydraulic tank.

When a function is activated, the open centre starts to close, which causes the pressure to rise. At the same time, the passage to the cylinder begins to open. The more the spool shifts, the more the open centre closes, and the more the pressure is increased. When the pressure is higher than the cylinder pressure, the cylinder begins to move, but oil that is not directed to the cylin-der is returned to the tank at a pressure drop, which, in turn, creates heat.

When the spool has been fully shift-ed, the open centre is closed, and the entire flow goes to the cylinder.

If the load is higher than the maxi-mum system pressure, the oil goes via the main relief valve back to the tank with a maximum pressure drop, which creates a great deal of heat.

load Sensing hydraulic SystemThe Load Sensing Hydraulic System, on the other hand, is a modern, well-proven and reliable system. It was origi- nally introduced for surface loaders, but is now available on the latest under-ground loader from Atlas Copco, the Scooptram ST14, thoroughly tested at the Kristineberg Mine in Sweden.

Contrary to the Open Centre Hydra- ulic System, the Load Sensing Hydraulic System on the ST14 has two variable pumps working together. This provides exactly the right amount of flow and

efficient underground loading and haulageload sensing hydraulicsPowerful Scooptrams are vital to efficiency in underground loading and haulage. The objective has always been to provide a vehicle that can be relied on to deliver precisely the right amount of po- wer at exactly the right moment. This has been little more than a dream, until the introduction of the Load Sensing Hydraulic Sy- stem driven by a variable displace- ment pump. This is replacing the traditional Open Centre Hydra- ulic System driven by a fixed dis- placement pump, that has served many years as the industry stan- dard. Load Sensing Hydraulic System is a central feature on the latest Atlas Copco Scooptram ST14.

pressure at any one time, distributing the power wherever and whenever it is needed.

As the system is activated only when moving the control stick, only a mini- mum of pumping power is lost, thereby reducing fuel consumption. Further- more, the hydraulic system is faster, which means shorter working cycle times and higher productivity, and gives the operator better control of the load, resulting in a smoother, more comfort-able ride.

The spools in the Load Sensing Hy- draulic System are “closed centre”,

which means that when no function is activated, no oil flows through the system. The pump strokes back to zero flow, and maintains only a low standby pressure. As soon as a function is ac- tivated, a pressure signal from the cylinder port is fed back to the pump, which then regulates to a pressure level just above the highest load.

This means that the pump only de-livers the flow that is needed at the re- quired pressure level, and that no oil is throttled back to the tank, creating heat. If the load is higher than maximum sy- stem pressure, the pump strokes back

and holds the maximum pressure at zero flow, again saving energy.

The capabilities of the Load Sensing Hydraulic System enable the use of a stiffer converter with a higher degree of efficiency that transfers more of the power to the driving wheels, and redu- ces the amount of heat loss. This results in a higher speed on grade for the Scoop- tram ST14, and maximum utilization of the installed diesel power. This results in improved performance, minimum power losses and lower overall fuel consumption.

Power losses

Small movements under high pressure in conventional hydraulic systems al- ways lead to substantial power losses, and the use of the bucket is a good ex-ample. It is common practice to move the bucket slightly, to make it easier to penetrate the muck pile.

With the Open Centre Hydraulic System, a large amount of thrusting power is lost each time the hydraulic oil is activated and directed to the bucket-moving cylinders, reducing the amount of power retained for traction. With the modern Load Sensing Hydraulic System, more than enough power is retained for both bucket movements and traction, and the traction power drops only marginally with each small bucket movement.

The tests carried out with the Scoop-tram ST14 prove the point. The extra wheel spin caused by the increased amount of available power was easily compensated. By easing up on the throttle, and attacking the muck pile at lower revs, the operators found they could get excellent traction, and save fuel at the same time.

To summarize, the search for in-creased efficiency in underground load-ing and hauling operations is satisfied by a vehicle that can deliver the exact amount of pressure and flow required for each function. Load Sensing Hy- draulic Systems in underground equip-ment such as the Scooptram ST14 are a milestone for Atlas Copco, and a major step forward for the industry.

In an open centre system, the hydraulic flow (the horizontal axis) is determined by the engine speed (revs). Consequently, a large amount of unused oil is pumped through the system unnecessarily, with corresponding power losses and heat build-up. In a load sensing system, the hydraulic flow is determined by the actual demand, and the pump only delivers the required flow at the required pressure level. No oil is throttled back to the tank, to create heat and power losses. In both systems, the hydraulic pressure (the vertical axis) is determined by the actual pressure requirement. By choosing the Load Sensing Hydraulic System for the Scooptram ST14, the speed on grade has been increased by up to 14%. During mucking, it is possible to move the bucket with minimal losses of traction force.

natural choice

Underground mining operations with production processes that are exceptio-nally deep, unusually difficult to access, or extremely hazardous are typical en- vironments that make automation and self-operating equipment a natural choice.

Mining companies currently invest in automated equipment as a means of increasing safety, reducing manual re-petitive work, and increasing overall effi- ciency and productivity.

As one of the world’s leading suppli-ers, Atlas Copco has been instrumental in developing much of the automation technology that is available for the mo-dern mining industry. This includes everything from computerized control and guidance systems on large under-ground drill rigs and loaders, to remote control and satellite hole navigation sy-stems on surface crawler rigs.

The aims of such innovations are to consistently reduce human exposure to the harsh and dangerous environment of underground mining and at the same time increasing efficiency and equip-ment utilization.

Scooptram ST14

The recently launched Atlas Copco Scooptram ST14 is a typical example. Vehicles were tested at Boliden’s Kris-tineberg Mine in Sweden, and at Inco’s Stobie Mine in Canada. Other units are being delivered to mines in Sweden, Canada, Portugal, Chile and Russia. This new loader design reduces the physical strain on the operator by making better

use of available power. The bucket pen-etrates the muckpile easier and quicker, and is filled to capacity at every attempt. This increases the number of loads per shift, with corresponding improvements in productivity.

These productivity and safety ben-efits are derived from applying the company’s RCS (Rig Control System) and ABC (Advanced Boom Control)

systems witch are already installed on most of its Rocket Boomer, Simba and Boltec underground and rigs.

Rig Control System

The ABC system offers three modes: ABC Basic, Regular or Total. These cor- respond to manual, semi-automatic and fully automatic operation. ABC Total is

the mode that is now gaining the most ground, offering accurate and precise hole collaring, and faster drill and blast work cycles. Developments such as these are designed to keep efficiency high and costs low, so that miners can meet the future challenges of the industry with confidence.

As most of the tonnage in tomorrow’s world will be extracted using mecha- nized equipment, automation makes per- fect sense. But more importantly, it is getting harder and harder to find new deposits. When they are found, they are generally more difficult and more ex-pensive to mine than before. The new mines are often located in remote areas, which are not the most attractive for re-cruiting the best-qualified people. To mine these deposits profitably, automa-tion will not just be an option, it will be a necessity.

Centre of excellence

When the LKAB-owned mines of Kiruna in northern Sweden became mechanized in the 1980s they worked in close co-operation with Atlas Copco to develop drill rigs and systems that could be controlled at a safe distance from the mining area. These rigs now also run during night shifts in automatic mode, entirely without supervision. To- day, Örebro in the heartland of Sweden is the centre for Atlas Copco research and development in this field.

The region has a long tradition of mining, and it was in Örebro that Atlas Copco developed its first Rig Control System (RCS) in 1996. Since then it has become the standard for drill rig applications and the platform for all

subsequent automation innovations by Atlas Copco.

The PC-based RCS platform, and its associated modules, considerably redu-ce the wear and tear to which mining equipment and personnel are normally subjected. They make operations faster and lighter, and make the equipment easier to handle and maintain.

Much of the communication with today’s rigs is handled through the In- ternet, satellite and telephone, taking production planning and fault-finding to a higher level.

Automation in action

Other examples of progress from auto-mation are automatic bit changers and automatic tunnel profiling systems.

Measure While Drilling MWD, a sy- stem for the logging of rock strata charac- teristics using the rock drill as a sensor while drilling the blast holes, is also a product of automation. Using MWD, the logged data is transferred to a PC for further analysis and interpretation. The resultant data gives a prediction of the geology ahead of the face, which is in-valuable when drilling in mixed strata.

The focus is increasingly on the use of technology to preview reality. For ex-ample, it would be hugely advantageous to show the loader operator what the muck pile looks like before he drives in, to show the driller what the orebody looks like before he sets up the rig, and to show the blaster what the hole looks like inside before he commences charging.

LHD automation applications cur-rently are in the whole production cycle - from teleremote mucking, autonomous

tramming to dump site, auto dumping and then return autonomously to the drawpoint for the next loading cycle. There are also trucking applications where the trucks are loaded by LHDs or by chutes and then tram autonomously to the dump site, dump the load and tram back to loading area. Productivity improvements, as well as maintenance savings, are becoming real through all these various projects mentioned above.

Automated systems provide real- time information to the management and supervisors of these mines, not to mention the operator of the system. This is for accurate planning, scheduling and measuring the process.

Atlas Copco has learned that, wher-ever mining and construction activities may be located, we must continually strive to make improvements, and we must never stop trying to increase effi-ciency for our customers.

- Automation is the key.

Aftermarket

Aftermarket Marketing Department is responsible for spare parts policy. The characteristics of the part greatly affect the way the spare part level is set. If a part assembly module includes any wear parts or consumables that need to be changed within a regular time interval, these parts are generally also sold loose or in a kit. If a part is highly advanced technologically, or has tight tolerances that may complicate the service or re-pair, it is generally sold as a complete functioning unit.

Our spare parts are easy to disassemble and assemble on the machine at site, without needing to send the vehicle to the workshop. Thought is given to whether special tools are needed in order to properly carry out the service or repair.

Aftermarket publishes a range of brochures and a handbook covering its activities.

One service- one part number protocolCustomers gain many advantages by using parts kits instead of ordering in- dividual parts and tools separately. Not only do the kits contain everything ne-eded for a service, rebuild or overhaul but they will also save time when carry-ing out the work. Instead of searching for parts, the customer only has to open up the kit box to find everything required for servicing his machine. The kits are based on the parts needed for each

specific job, to meet the service interval stated in our maintenance manuals.

Our parts kits feature: selected quality parts and tools for servicing and over- hauling machines; a solid box container for secure shipping and handling at the job site; one part number, under the one- service-one part number protocol; and simplified service requirements.

The advantages of using genuine Atlas Copco parts kits are: machine products are maintained to factory specifications, thus optimizing economic production; easier order handling and logistics; and the price is most competitive compared to buying individual items.

Thin seam, high output

Waterval Mine is near Rustenburg, about 150 km northwest of Johannes burg. It is one of Anglo Platinum’s newest mines, and will be making its contribu tion to the group’s target by excavating 3.2 million t/year in an orebody just 0.6 m-thick and on a decline of nine degrees. Despite the low seam and restricted mi-ning space, Anglo Platinum was convinced that it could tackle the task successfully, and opted for the room and pillar method with ramp access, to gether with mechanized equipment. The mine design meant that the rooms would be extremely confined, with a height of 1.8-2.0 m. This, in turn, meant that head-ings would have to be as low as possible, and the equipment extremely compact. Anglo Platinum also in sisted that quan-tum im provements be made at the mine in three priority areas: safety, production and pro ductivity, in that order. Potential suppliers were assessed by Wa-terval engineers. Atlas Copco was the only company able to provide a total solu tion around the three key mining tools needed: loader, drill rig, and bolting rig. These needed

to be low profile, compact and techncally advanced, spe cially designed for low seam work and exacting environments. In addition, Atlas Copco agreed to act as a cooperation partner in all aspects of the rock excavation process, providing opera-tor training, spare parts supply and service and maintenance.

Purpose matched package

The equipment trio comprised the Atlas Copco Scooptram ST600LP loader, the Rocket Boomer S1L drill rig, and the Boltec SL bolting rig. The units were progressively delivered to Waterval, until there were 23 Scooptram ST600LP loaders, 15 Rocket Boomer rigs, and six Boltec units at the site. The Scooptram ST600LP, also known as the Ratel, is a compact LHD with a height of around 1.5 m. It has a 6 t loading capaci-ty, and is equipped with a special bucket for low height work. It is powered by a clean burning 136 kW Deutz diesel engine. The Rocket Boomer S1L has well-proven, heavy duty Atlas Copco compo nents such as the COP 1838 rock drill, BUT 28 boom, and BMH 2837 feed. The Boltec SL is a high production, semi- mechanized rock bolting rig with an electri-cal remote control system. Apart from stan-dard rockbolt installation, it is also equipped

loading in low headroom at WatervalBoosting productionThe Anglo Platinum Group of South Africa, the world’s leading plat inum producer, has completed an ambi-tious plan to boost its annual output by 75% from 2.2 million ounces to 3.5 million ounces by the year 2006. This tough target would have been a daunting prospect for most mining companies, especially in conditions at its Waterval mine, where headroom seldom exceeds 2.0 m. However, Anglo Platinum, which accounts for more than half of the total platinum produced in South Africa, has very extensive experience of low seam operations. This experience led the company to Atlas Copco, who sup-plied a com plete equipment package to Waterval’s specification to meet all of its low headroom loading, drilling, and rock bolting needs.

to perform long hole drilling for anchor and cable bolting. The Boltec SL uses the same carrier as the Rocket Boomer S1L, bringing advantages of commonality. The equipment complement for each min- ing section is one Rocket Boomer, one Boltec, and two Scooptram ST600LP loaders.

Production Drilling

The layout at Waterval is divided into 12 sec- tions with nine panels or stopes. Each panel averages 12 m-wide x 1.8 m-high, with pil-lars of approximately 6 m x 6 m. The dril-lers work three 8 h shifts per day, six days a week and their target per section is 23,000 t/month. That translates to 200 t per panel, or two panels per shift. Some 68-74 x 3.4 m-long holes are required in each panel, taking around 2.5 h to drill. Three 77 mm holes form the cut, and the main round is drilled using Atlas Copco Secoroc model –27 R32 43-45 mm bits. Ramps from the surface provide the ac-cess for men, machines and supplies, and also accommodate conveyor belts for trans-porting the ore out of the mine. The mine expects each Rocket Boomer rig to yield around 200,000 t/year. For rockbolting, 1.6 m-long Swellex bolts

are used, in a standard bolting pattern of 1.5 m x 1.2-1.5 m. The Boltec SL is equipped with Secoroc Magnum SR28 Tapered Speedrods, with 38 mm model -27-67 bits for Swellex installation. The tramming height of the Bol- tec SL is just 1.30 m, with ground clearance of 0.26 m. It is equipped with a COP1028HB rock drill, and can insert a Swellex bolt of length up to 1.6 m in roof height of 1.8 m. With so many available faces in close proximity to each other in the room and pillar layout, utilization is a key factor for main-taining a high level of productivity and effi-ciency. The required utilization for the drill rigs ranges from 50 -75%, and availability is about 90%.

low height loading

The Scooptram ST600LP is an extremely robust loader designed specifically for de-manding thin seam applications where the roof heights are as low as 1.8 m. For visibi- lity on the far side of the machine, video ca-meras point to front and rear, displaying the views on a screen in the driver’s cab. Loading from the different rooms is a crucial part of the operation, and the spe-cially designed E-O-D (Eject-O- Dump) 6 t-capacity bucket on the Scooptram ST600LP makes low height work easy. Using the E-O-D bucket, the rock is pushed out by a push plate onto feed ers that transfer it to the conveyor system for transportation to the sur- face. The Scooptram loaders are refuelled underground and generally drive up to the surface for maintenance. At Waterval, Anglo Platinum gives top priority to dilution and utiliza tion. The amount of rock waste must be kept to an absolute minimum, and the fact that this can be achieved with mecha nized equipment in such a low, flat seam is seen as a major ac-hievement. To ensure high availability of the equip-ment, Anglo Platinum and Atlas Copco have entered into full-service contracts that pro-vide for 24 h service and maintenance. It makes good business sense for the mine to have a service contract manned by specia-lists with the technical know-how and skills for optimal maintenance.

Barroca Grande: home to the world´s largest tungsten mine.

introduction

The Panasqueira mine is located at Barroca Grande in a mountainous region of Portugal, 300 km northeast of the capital city of Lisbon, and 200 km southeast of the port city of Porto.

The mining concession lies in moderately rugged, pine and eucalyptus covered hills and valleys, with elevations ranging from 350 m above sea level in the southeast to a peak of 1,083 m above sea level in the northwestern corner.

The concession area is an irregular shape trending northwest-southeast, and is approx-imately 7.5 km-long. It is 1.5 km-wide at the southeastern end, and 5.0 km-wide at the northwestern end, where the mine workings and mill facilities are located.

The geology of the region is character-ized by stacked quartz veins that lead into mineralized wolfram-bearing schist. The mineralized zone has dimensions of approxi-mately 2,500 m in length, varying in width from 400 m to 2,200 m, and continues to at least 500 m in depth.

Production levels

Access to the mine’s main levels is by a 2.5 m x 2.8 m decline from surface, with a gra-dient of 14%. The main levels consist of a series of parallel drives that are spaced 100 m apart, and which provide access to the ore passes for rail transport, and connect with ramps for movement of drilling and loading equipment.

There are seven veins between the 2nd and 3rd Levels, which are 90 m apart. The veins are almost flat, but occasionally split or join together. They pinch and swell, and are usually between 10 and 70 cm-thick, and can plunge locally as much as 3-4 m in a very short distance.

Blocks of ore are laid out initially in 100 m x 80 m sections by driving 5 m-wide tun-nels, 2.2 m-high. Similar tunnels are then set off at approximately 90 degrees to create roughly 11 m by 11 m pillars, which are ulti-mately reduced by slyping to 3 m by 3 m, providing an extraction rate of 84%.

Blasted ore is loaded from the stopes by a fleet of six low-profile Atlas Copco Scooptram

keeping a low profile at PanasqueiraOne hundred years of historyPrimary Metals Inc (PMI) is owner of the Panasqueira mine in Portugal, in production for over 100 years, and still the largest single source of tung-sten in the world. Thin seams in low headroom make the mining tricky, but Atlas Copco Portugal was able to come up with the perfect package of low headroom mining equipment, including its increasingly popular Scooptram ST600LP. PMI also chose Atlas Copco Finance for funding the fleet purchase, agreeing a simple sup- plier-credit arrangement tailored to match the demands of the operation. As a result, overall mine productiv-ity has increased by 25%, and daily production records are being broken. Above all, the partnership between equipment supplier and end-user is proving to be progressive and profit-able!

ST600LP loaders tipping into 1.8 m-dia-meter bored raises connecting to the main level boxes.

Rail haulage with trolley locomotives is used to transport the ore to the shaft on Level 3, and to the 900 t-capacity main ore- pass on Level 2 that provides storage for the 190 t/h jaw crusher located at the 530 m- level.

Crushed ore discharges onto the 1,203 m- long, 17% inclined Santa Barbara conveyor belt that connects with a 3,000 t-capacity coarse ore bin located beneath the mine office.

Primary mine ventilation is provided naturally by several ventilation raises. Airflow is controlled by curtains in main areas and assisted by axial flow fans where needed, particularly in the stopes.

Compressed air is needed for the charg-ing of the blast holes with ANFO, and a new

compressor unit was installed underground in 2002.

The mine is supplied by 3.0 kV electri-cal power, which is reduced to 380 V for distribution to equipment.

Mining method

The stoping process begins when spiral ramps are driven up to access the miner-alized veins, and the orebody is opened in four directions and blocked out.

East-west oriented tunnels are called Drives, and those trending north-south are called Panels. Drives and Panels are driven 5 m-wide and, where they intersect, 1.8 m-diameter raises are bored between haul-age levels to act as orepasses for all of the stopes. Chutes are installed in the bottoms of the orepasses to facilitate the loading of trains.

The height of the stopes is nominally 2.1 m, but can increase to 2.3 m in areas where ore bearing veins are more variable in their dip, strike or thickness.

Precise survey control is maintained, so that all final pillars are aligned vertically. Experience has shown that the stopes will usually begin to collapse about 4 or 5 months after extraction, which gives plenty of time to glean any remaining fines from the floor.

jumbos. Rounds are drilled 2.2 m-deep, utilizing a Vee-cut, and 41 and 43 mm-diameter drill bits. Drilling is carried out on two shifts, with about 28 holes required per 5 m-wide round.

ANFO is loaded pneumatically into the blast holes, and electric delay detonators along with small primers are used for blast-ing. Blasting takes place around midnight, and the mine then ventilates throughout the night.

Each blasted face produces about 60-65 t of rock, and each rig can drill up to 10 faces/shift, depending upon the availability of working places.

After the blast, the muck pile is washed down, and the back is scaled. Ore is loaded and hauled by the Scooptrams from the headings to the orepasses.

Once the limits of the stopes are estab-lished, then the final extraction takes place with 3 m x 3 m pillars created from the perimeter retreating to the access ramp.

Drilling performance

The mine drill rig fleet comprises three Atlas Copco Boomer H126L drill rigs mounted with COP 1238ME rock drills; five Atlas Copco Rocket Boomer S1L low-pro-file drill rigs mounted with COP 1838ME rock drills; and three older drill rigs ret-rofitted with COP 1238LP rock drills. All drilling uses ballistic button bits, of which the preferred 43 mm-diameter Atlas Copco

Secoroc SR35 bits used by the COP 1838 rockdrills are returning 370 m/bit, while the 41 mm-diameter bits are returning 450 m /bit. In such abrasive rock, bit wear has to be closely monitored to avoid an escalation in costs. Likewise, regrinding has to be to a high standard.

The recent addition of Rocket Boomer S1L models to the fleet has resulted in a 50% increase in output/drill rig, while less waste rock is generated due to the lower profile required for safe operation. This drill rig will operate in a seam height as low as 1.3 m and is equipped with four-wheel drive for maximum tractability. The COP 1838 rock drill has double reflex dampening for high-speed drilling and excellent drill steel economy.

Atlas Copco Scooptram ST600LP in low headroom stope.

Drilling is performed primarily on day and afternoon shifts on around 50 faces. These are maintained in close proximity to one another, to avoid long moves for the drill rigs.

Scooptram ST600lP

Each Scooptram ST600LP cleans 4-6 head-ings/shift on a maximum 200 m round trip to tip, consuming 12 lit/h of dieseline.

The ST600LP is an extremely robust LHD designed specifically for demand-ing low seam applications where the back heights are as low as 1.6 m. It has an operat-ing weight of 17.3 t and a tramming capa-city of 6 t, equipped with a 3.1 cu m bucket. It is 8.625 m-long, 1.895 m-wide and 1.56 m from floor to top of canopy. It is powered by a robust 6-cylinder diesel engine, provid-ing a mechanical breakout force of 8.7 t and hydraulic breakout force of 9.3 t.

For visibility on the far side of the ma-chine, video cameras point forward and aft, reporting to a screen in the driver’s cab. The model has gained a well-deserved reputa-tion in the platinum, palladium and chrome mines of South Africa, where gradients are steep and rock is highly abrasive. The ST600LP is now proving itself in similar rigorous conditions at Panasqueira, where the roof is not well defined, and there are frequent seam irregularities.

Mechanization pioneer

The official name of the Proano mine comes from Captain Diego Fernandez de Proano, who discovered the site and developed the first mining works on the hill that bears his name. The operation is also known as Fresnillo mine because of its proximity to Fresnillo city. It is run by the Compania Fresnillo, SA de CV, which is 100% owned by Penoles.

With a history that can be traced as far back as the 1550s in Pre-Hispanic times, Proano has gone through a number of pha-ses, which have left an important mark on the mine. Its operations have been stopped due to economical and technical difficul-ties (1757 to 1830), as well as during the Mexican Revolution (1913 to 1919), and in-evitably it has gone through several owner-ship as well as technological changes.

From employing basic manual tools in the early days, the mine now employs mo-dern mechanized units, including some of the most sophisticated mining machinery available.

Embracing mechanization early on has been one of the factors that has helped Proano cement its position as the world's largest and most profitable silver mine. They started mechanizing operations about 40 years ago, and during the last 30 years there has been a steady increase in production. Products are silver-lead concentrates and silver-zinc concentrates. In 2005, Proano produced

nearly 34 million troy ounces, or 1,055 t, of silver.

Production expansion

During the mine's long history it has had to adapt to changes in the geology and work parameters. For instance, the mining method has had to be fundamentally changed several times, and each time the appropriate tech-nology and equipment has had to be intro-duced. Atlas Copco has worked alongside the mine management for several years to adapt and innovate with primary equipment, service, training, inventory management an parts stock. The mine recently implemented

getting the best for PenolesSpecial operationsIndustrias Penoles’ Proano and Fran-cisco I Madero mines are very special operations. Both underground mines, Proano is a 450 year-old operation and the richest silver mine in the world, and FIM is just six years old and the largest zinc mine in Mexico. Located in the central state of Zacatecas, both mines are key users of Atlas Copco eq- uipment, which includes Scooptram and Minetruck products. Penoles has decided to standardize its whole mi-ning fleet on Atlas Copco equipment to obtain maximum benefit from the service and distribution centre in nearby Caleras.

a substantial production increase, going from 4,500 t/day to 7,000 t/day.

To support this production expansion the company recently increased its mining fleet with the purchase of three Rocket Boomer 281 development drill rigs additional to its four existing units, another Simba M4 C production drill rig additional to its existing three units, five Scooptram ST1020 loaders to complement its existing fleet of 17 units, and two MT2000 trucks to increase its fleet to seven units. Atlas Copco has also started a service contract for the Simba rigs, which requires the presence of four technicians on site, and offers similar assistance for the loaders.

Currently, the Proano mining fleet rep-resents a mix of old and new Atlas Copco technology. Amongst the old units are ST 6C loaders, BBC 16 pneumatic rock drills, BMT 51 pusher leg rock drills and DIP & DOP pneumatic pumps. There are also Diamec U6, Diamec 262 and Diamec 252 exploration drill rigs, Boltec 235 bolting rigs, Rocket Boomer 104 drill rigs, Simba 1254 production drill rigs and Robbins raise borers. Furthermore, the mine uses Secoroc drill steel on development and production rigs.

Proano was the first mining operation in Mexico to employ the Boltec rigs and the Rocket Boomer 281 rig with telescopic advance, which represent completely new technology.

Likewise, Proano owns two Diamec U6 APC deep hole drill rigs, the first mine in the Americas to use this type of machine.

During the first three months of 2006, the entire Atlas Copco mining fleet at Proano achieved a physical availability of 89.5% against the objective of 90%.

Atlas Copco's commitment to Proano goes beyond providing new equipment, and a few years ago it decided to set up a distri- bution & service centre in Caleras, Zacatecas.

Mining operations

The underground operations can be acces-sed either through two shafts, Central Shaft and San Luis Shaft, or by one of the mine's several ramps.

The mine has seven levels, and in Level 425 is the San Carlos orebody which cur-rently produces 67% of production.

Proano carries out about 40,000 m of de- velopment drilling a year. To support this work, there are three different contracting companies: Mincamex, Jomargo and Mecaxa. All three companies own Atlas Copco equip- ment, mainly Rocket Boomer drill rigs and Scooptram loaders.

The mining method is cut & fill using upwards and downwards drilling. However, the amount of drilling and the hole diameter have changed over the years.

They went from drilling 20 m downwards and 10 m upwards to drilling 22 m down-wards and upwards. Then changes in the ore- body allowed use of long hole drilling em-ploying Simba rigs with top hammers.

The base main level is serviced with elec- tricity, water and air, from where the sub-levels are supplied. Currently, the miners drill 25 to 32 m downwards and 25 to 32 m upwards, using a computerized Simba M4 C DTH rig from a single set up.

Community & environment

The expansion of the Fresnillo city through the years means that Proano's operations are now situated almost inside the city. The com- pany has taken this fact as an opportunity to develop a good relationship with the com-munity.

In order to diminish the environmental impact of its operations, the company has invested in the installation of environmen-tally friendly equipment and machinery. Proano has an ISO 14000 Environmental Management System certification and has also been awarded a Clean Industry Re- gistration by the Mexican environmental authority.

Furthermore, the company has founded an ecological park, which is a sanctuary for several species of mammals, birds and rep- tiles. Nearby, there is also a tourist mine, and a mining museum to make the public familiar with the mining process and to pre-serve the history of the industry. In 2004 the company opened the Parque los Jales, a public area that includes lakes, paths and open areas for physical exercise and relaxation. This facility was built on the land formerly occupied by the tailings pond.

new operation

Located about 15 km north of the city of Zacatecas, Francisco I. Madero (FIM) is one of Penoles' newest mines, having start-ed commercial production only in 2001. The mine's name comes from a former Mexican President, Francisco Ignacio Madero, killed during the Mexican Revolution. Although a polymetallic mine with reserves of gold, silver, copper, lead and zinc, FIM's main products are zinc concentrates and lead con-centrates. At the end of 2005, the mine had reserves of 27.5 million t with an average zinc grade of 3.3% and 0.74% of lead.

With an investment of US$125.8 million and a production capacity of 8,000 t/day, in 2005 FIM produced a total of 65,948 t of zinc concentrates, and during the first se-mester of 2006 produced 31,572 t.

The mine is equipped with a radio system for internal and external communication through a network of coaxial cables in the production levels, development areas and mining infrastructure. This system incor-porates voice, data and video channels for communication between personnel, accident reduction, production control and location of vehicles and personnel.

Atlas Copco started working with the Penoles' team in charge of the FIM project in October, 1997 and has continued to provide technical support in the planning and devel-opment of the mine. The first order from the mine was for four Rocket Boomer L1C and three Rocket Boomer L2C drill rigs with single and twin booms respectively. These rigs, which have enclosed, air conditioned cabs, feature ABC Regular computerized drilling system with communication ports and protocols for PC, failure and anti jam-ming systems. FIM also ordered eleven ST8C loaders with weighing system, real time communication system via leaky feeder to a control centre, and auto-diagnostic system

with data port. The first machines arrived in 2000.

This initial fleet has subsequently been expanded to include: two Robbins raise-borers, a 61R and a 63RM; three SB 300 scalers; a Craelius Diamec U6 exploration rig; a Simba production drilling rig; and two Boltec 235 bolting rigs.

Furthermore, Atlas Copco Mexicana and FIM have an important maintenance con-tract, which has been running for six years. This is the largest such contract that Atlas Copco has in Mexico, and comprises a team of around 20 people including mechanics and supervisors, directly supported by their Caleras distribution & service centre.

According to the management at FIM, the Atlas Copco equipment has contributed to the rapid and safe advance in production at this mine.

FiM mining operations

For development and production work, FIM employs several contracting companies, amongst which are Minera Castellana, which also carries out exploration work. Contrac-tors Arconso and Paniagua Obras Mineras both conduct development work.The latter has a specific contract to conduct at least 200 m/month of development work using an FIM Rocket Boomer L1C rig eq-uipped with COP 1838 drill and one of the Scooptram ST8C loaders. Around 235 m of development has been achieved in a month.

The ST8C loader operator is very happy with the machine, which is the most modern

equipment he has worked to date. He finds the controls easy, and had no problem learn-ing to drive.

Because of the generally poor ground con- ditions, FIM employs cut & fill with pillars as its mining method. It has been the method of choice since operations started. It opens voids of 8 to 10 m, bounded by non-recover-able pillars of 6 m in a square section. It has a mineral recovery factor of 86% to 90%.

For production, horizontal and verti-cal drilling is used in a ratio of 30:70, but that will change by mid-2007 to 100% long hole drilling angled 75 degrees upwards. The roof is expected to be subjected to less damage, and less support should be needed. The risk of rock falls is also much lower.

This is similar to methods used at Proano, so their experience will be most useful.

FIM uses a mixture of shotcreting and bol- ting, and recently acquired two Boltec 235 roof bolters with COP 1532 drills. Each ma- chine regularly installs nine roof bolts per hour, or 56 per shift. Depending on the quality of the rock, up to 70 bolts/shift have been installed.

On average, about 2,400 bolts/month are installed. Tests at the mine prior to purchase of the Boltec bolting rigs revealed that the bolts were taking 17 t each.

Most of the mined material is unloaded by gravity directly to a crushing station. The rest of the production is hauled in 40 t-capacity trucks in a closed circuit of hori-zontal haulage on the general haulage level, located at 210 m from surface.

A conveyor belt is installed in a 4 x 3 ramp with an inclination of 21% and a length of 1,290 m from level 2022 to the surface.

For personnel access, mining equipment and general mining services, there is a 4.6 m x 4.0 m ramp with an inclination of 13.5% and 1,790 m length between surface and the general haulage level.

Maintenance

To deliver its maintenance contract, Atlas Copco has its own facilities at the mine, backed up by the distribution and service centre in Calera. The contract includes pre-ventive and corrective maintenance, and fol- lows a programme already prepared for all the Atlas Copco fleet.

The service contract has a specific pro-gramme every week depending on the ma- chines to be serviced. About 50% of the machines have been working for between 18,000 and 20,000 hours without any rebuild, which is a good reference for the quality of the equipment. The contract also involves operator training.

Competitive trial

Kristineberg is Sweden's deepest mine and has been in operation since 1940. It produ-ces 550,000 t/year of ore containing zinc, lead, copper, gold and silver. Early in 2006, the new Atlas Copco Scoop- tram ST14 equipped with Load Sensing Hydraulic System was put through its paces in daily production at the mine, alongside a larger similar machine. Performance data was recorded, and comparisons made. After 1,500 hours of operation, it was already appa- rent that the ST14 was emerging as a clear winner. Most noticeable during the trials was the ready availability of power for penetrating the muck pile, manoeuvring and filling the bucket, ramp haulage and traction. Operators in mines like Kristineberg place high demands on their equipment. First and foremost, they need a loader that is very strong and easy to handle, but comfort is al- ways a close second. In particular, they want to be able to stretch their legs out proper-ly while driving, instead of half-standing, which has been a perennial problem with other machines. The new air suspended seat on the Scoop- tram ST14 is also rated as a big improve-ment. When working long shifts, the Scoop-tram ST14 offers a good seating position and

a comfortable, clean environment, which is a major contributor to improved produc-tivity. The operators report that the machine has exceptional power, both for attacking the muckpile, and for tramming. The quick and powerful bucket action is also much better than on comparable loaders. The bucket is filled in next to no time, reducing the lo-ading cycles by a significant margin. From a servicing point of view, the ope-rators are very much in favour of the ST14 because there is no need to climb on top of the body to reach awkward places. All of the daily operator servicing can be carried out at ground level. Safety and operator comfort have been major goals for the ST14 designers, who have improved visibility and added the uni- que footbox to give the operator extra le-groom.

Scooptram ST14 earns top ratingload sensing hydraulicsThe first Atlas Copco Scooptram ST14 to be equipped with a Load Sensing Hydraulic System was highly praised during trials at the Kristineberg mine in Sweden. The system distributes the hydraulic oil to the machine's various cylinders at the right pressure, at the right time, and with a minimum of po- wer loss, irrespective of whether several functions are activated at the same time. The result is a loader that is more responsive, faster to fill, quicker on grade and easier to handle. The operators were impressed by the ready availability of power to pene-trate the muckpile and fill the bucket in one pass, while the management wel- comed the improved productivity.

Business class

The new Scooptram ST14 loader provides operators with a high level of comfort. Based on the principle that job satisfaction has a significant impact on productivity, Atlas Copco designers have put the operator's safety, comfort and working environment first, a strategy that has been highly praised at Kristineberg. Giving full consideration to the physical demands of the job, the improvements have been well thought out and very cleverly designed. As a result, visibility from the cab is ex-cellent, the sitting position is ergonomically correct, the amount of legroom is unique, and the ride is comfortable and pleasurable. Atlas Copco's attention to ergonomic de- sign and the working environment has result- ed in a loader that provides operators with the kind of comfort usually associated with business class travel. The driving seat is air suspended and sof-ter and more comfortable than in any other LHD. This has been made possible by the location of the controls in the armrests, and the footbox concept, which resulted from re-engineering of the drive train design to create more free space in front of the cab.

There is also more free space around the operator, and the long wheelbase makes for a smooth, comfortable ride. An effective ride control system contributes to smooth tram-ming, allowing the vehicle to be driven at speed while still maintaining maximum comfort. Superior visibility has resulted from the combination of large windscreens, the clean, flat top of the vehicle body, and the drive train design with its short and low-level rear end. The environment inside the cabin is both spacious and clean. The designers have avoided the use of textiles, and have instead used materials that are easy to keep clean and free from dust. Climate control, with no hydraulic hoses in the cab, also contributes to a good en-vironment, controlling air temperature and quality, and improving safety.

Design targets achieved

With eight months of successful testing of the Scooptram ST14 behind them, the At-las Copco design team were able to confirm that their targets had been met.

The ST14 meets the highest safety stan-dards, and its ergonomics are much appre-ciated by the operators. Reliability is very high, as the same power train is used as in the proven ST1520, and performance is above expectations. It was a challenge for the ST14 to be judg- ed by operators with long experience dri-ving Kristineberg's 16.5 t-capacity loaders.

However, the ST14 has proved to match, or even exceed, the output of the larger loaders. All of the teething problems have been addressed, and necessary improvements have been introduced on the assembly line. The Scooptram ST14 proves the concept that an investment in an exceptionally good working environment is an investment in increased productivity. Operators of the ST14 feel healthier, experience greater job satisfaction, are more motivated, achieve more, and still have plenty of energy left over after finishing a long shift.

ST14 at Frood-Stobie

CVRD Inco’s Frood-Stobie mine in Sudbury, Ontario has been in operation since 1911. It is one of Canada’s oldest and largest pro-ducers of nickel. The three mining divisions have two shafts, the deepest of which goes to the 4,075 ft level. During 2006, more than 3 million tons of ore was mined using a combination of sub- level cave and VRM method. This deman- ding environment provided the perfect testing ground for the new generation Atlas Copco Scooptram ST14, a much-anticipated addition to the latest range of underground loaders. The trials at Frood-Stobie provided infor-mation on Scooptram ST14 performance in what are considered to be typical Canadian mining conditions. Parameters such as capa- city, durability, fuel consumption, safety, ser- viceability, and ergonomics were all closely monitored. Operating in the mine’s Division ‘A’ produc- tion block, the Scooptram ST14 consistent- ly moved more than 100 buckets/shift of ore from the stopes. After two months on trial, the unit had clocked up 558 hours of operation. One of the areas of the mine where the ST14 was tested is at the 2,340 level, where it trammed approximately 180 m to dump into the ore pass that feeds the 2,600 level. The complete cycle from the muck pile to the ore pass and back averaged three minu-tes, with excellent bucket fill.

These results were proof positive to the operators and mechanics engaged in docu-menting the performance and reliability of this technically advanced vehicle. In parti-cular, enthusiasm ran high with respect to its comfort, ergonomic design and servicea-bility. Operators reported that the Scooptram ST14 is a powerful unit in the muck pile, and handles as well as their smaller Scooptram ST8B. The comfort, visibility and state- of-the-art technology is impressive. Mining companies, including CVRD Inco, have also actively assisted Atlas Copco in the development of new loader technology to meet current industry expectations. The ST14 is designed not only to meet, but also to exceed these expectations. The trial at Frood-Stobie was successfully concluded at the end of 2006.

vehicle’s availability, productivity, and ope-rator comfort. The tramming speed of the ST1520 car-rying a full load has been praised by Beta Hunt management. They note that their ope- rators can muck out a heading faster with the ST1520, even though it has a smaller bucket than their other loaders. The ST1520 has the ability to tram nearly anywhere in second gear, and has never overheated whi-le it has been at the mine. The ergonomics and driver comfort were also quickly appreciated by the operators. The ST1520 is a lot more comfortable to drive over long periods for all sizes and

shapes of operator, with it’s foot box arran-gement and seating ergonomics. For a 15 t-capacity loader, the ST1520 is also relatively slim at less than 3 m-wide, allowing access to areas that were previous- ly out of reach for similar vehicles, and there- by contributing to overall productivity.

long history

Stawell Gold Mine, located about 250 km west of Melbourne, was first mined in 1853. It was closed in 1926, and stayed dormant for more than 50 years. It then re-opened in 1982, and has been in operation ever since. From 1992 until 2005, Stawell was owned by MPI Mines, who instituted a plan to in-crease gold production from 100,000 oz/yr to 130,000 oz/yr by end-2006. However, the mine recently changed hands, and is now operated by Perseverance Resour-ces, who have adopted the same objective. To meet these targets, bench stoping with cemented rock fill pillars in primary stopes is used. With this mining method, approx-imately 80% of the ore is recovered from the stopes. Remote-controlled loaders shift the ore out of the stopes, from where a fleet of five Atlas Copco MT5010 trucks is employ- ed hauling it to the surface along a gravel roadbed maintained by two graders in con-tinuous operation. Stawell management is convinced that the MT5010 is the best truck on the market in terms of load capacity and performance.

Faster is better

Stawell is a very deep mine with incline ac-cess. Inevitably, the adit is the bottleneck in the production operation, because it limits the size of truck that can be employed hauling

ore to surface. However, within the normal underground speed constraints, the faster the trucks, and the cleaner they run, the greater will be the amount of ore that gets to surface. At Stawell, getting the ore to surface in-volves an 10.5 km drive which, even with the MT5010, involves a round trip of 100 minu-tes. On the 1:8 gradient, its speed under full 50 t load is 12 km/h, some 2-3 km/h faster than the next fastest truck on the current market. This is because the MT5010 has the great- est power-to-weight ratio of any truck in its class, giving it the highest possible travel speeds per tonne. Based on the success of the site’s first MT5010, commissioned in 2003, the mine subsequently ordered another three, with the latest arriving on site in early January, 2005. Together, the new fleet has helped Stawell

high speed haulage at Stawellkeeping on trackTrucking ore from a depth of one kilo-metre beneath the surface can be a slow and expensive process, but it’s a thing of the past for the Stawell Gold Mine in Australia, where high speed haulage using a fleet of the latest Atlas Copco Minetruck MT5010 trucks plays a major role in the operation. Getting the ore out involves a long drive up the sublevel ramps at 1:8 to the 400 m level, and then on an incline of 1:10 to surface, a journey of 10.5 km. The drivers report that the MT5010 is the smoothest ride in their experience, and the management is obtaining their lowest-ever cost/t. The MT5010 is providing a very good return on investment!

to its medium term objectives while redu-cing the mining cost/tonne to the lowest it has ever been.

Comfortable power

The Atlas Copco Minetruck MT5010 is cur-rently offered with the Cummins QSK-19-C650 engine as standard. This water-cooled diesel provides an MSHA power rating of 485 kW (650 hp) at 2100 rpm, has a dis-placement of 19 litres (1,159 cu in) and a six-cylinder, in-line configuration. It is de- signed for maximum utilization with mini-mum maintenance. The articulated pistons are made to last 30% longer and also give 30% longer life after the engine’s first re-build. Oil seals have been engineered so they are never exposed to contaminants. The MT5010 is equipped with air condi- tioned ROPS/FOPS- cabin with forward- facing seat and back-up video monitor, and has an active hydraulic suspension system for improved operator comfort and hand-ling. Indeed, Stawell operators report that the MT5010 suspension is the most comfortab-le in their experience and provides a much softer, smoother ride, observing that, when working 12-hour shifts, this makes a dif- ference. The cab is also set up for efficient operation, with good driver visibility, clear instruments, and all controls easy to reach. One of the most noticeable and impres- sive features of the MT 5010 truck is its po- wer. The Cummins engine delivers torque of more than 3,000 Nm through the six-speed automatic transmission. From a standing start under load it pulls extremely well, whereas vehicles from the previous fleet struggled. It also has a tight turning circle, saving on backing out trucks in the limited space underground, and is a lot less tedious

to drive, being much faster than the earlier machines. The engine on the MT5010 is electronical-ly controlled for maximum fuel efficiency, minimum exhaust emissions and continu-ous diagnostic monitoring. This control sys- tem, along with an electronic transverter, provides smooth and precise gear changes. In addition to the selection of Cummins as the engine supplier, Atlas Copco has put the MT5010 through a series of more than 40 performance-enhancing upgrades to the engine, powertrain, cab, suspension, struc-tural body, and systems, which dramatically increase engine and component life. Servic-ing is fast and simple, thanks to easy access to filters, test points, and other parts which require regular maintenance.

Continuous support

The routine performed by the mine’s main-tenance team includes checking main func-tions after each 12-hour shift, as well as more thorough services at 125 hours, and the re-commended intervals of 250 hours. The MT5010s, despite their arduous work- ing situation, are acknowledged by Stawell management as being the best performing truck on site, with the highest t/km and ex- cellent availability. As a result, the MT5010s now comprise 70 percent of the hauling fleet. Where problems have been experienced, the mine knows it can rely on support from Atlas Copco. If they need a part, or a ques-tion answered, Atlas Copco provides a true, 24-hour service, seven days a week, and treats every enquiry with the correct degree of urgency. A technical training course on the MT5010 was conducted at the mine by At-las Copco to further enhance Stawell exper-tise. Many of the participants reported back that it was the best on-site training they had ever received from any equipment supplier, observing that Atlas Copco understands that aftermarket service and support is an im-portant complement to any sale. Future plans at Stawell include further exploration and deeper development work. In the next four to five years they plan to increase the mining depth to at least 1,300 m.

economic recovery

McCreedy West Mine, re-launched as a new venture in May, 2002, is already achieving revenues, and the prospects for long-term returns look bright.

Behind this revival is FNX Mining, head-quartered in Toronto, Canada. FNX Mining has a wealth of expertise for what has been described as the most advanced operation in the area. But there is an additional factor that makes a significant contribution to the overall effort – the successful co-operation between FNX Mining and Atlas Copco, in which Atlas Copco ensures the reliability of main drilling and haulage operations.

The opportunity to make a profit from these previously worked deposits depended not only on better metals prices. It also de-pended on the feasibility of refurbishing the mine infrastructure and on FNX’s abil-ity to exploit small mineral deposits in an efficient way.

FNX Mining is currently developing and mining from different locations in the mine, and using a limited amount of equipment on about 10 faces at any one time. In such an operation, versatility and equipment avail-ability are essential.

local cooperation

To meet these demands, FNX Mining chose to concentrate on Atlas Copco products and services. A contributing factor in the deci-sion was the efforts of the Atlas Copco sales

and service team, conveniently based in Lively, in the suburbs of Sudbury.

Based on a review of equipment avail-ability, costs and productivity to determine the lowest cost per tonne, the ST1510, as well as a Minetruck MT5010, were subsequently chosen for the McCreedy West project.

McCreedy has 120 employees working on two 10-h shifts a day. The deposits are quite widely dispersed across five zones from levels of approximately 213 m to below 490 m (200 ft to 1,600 ft) with an average head grade of ore mined at 1.7% nickel.

FNX Mining uses primarily mechanized cut-and-fill, following narrow veins. Current operations use an Atlas Copco Boomer 322 twin-boom jumbo and Scooptram LHD s for loading. However, the mine and its staff are flexible, using whatever safe mining meth-ods are required to get at the paying ore in the most economical way.

Revival in the Sudbury BasinSuccess at McCreedy WestThe Sudbury Basin area of Ontario, Canada is currently enjoying a revival in the fortunes of the mining industry following an increase in world prices for nickel, the metal that made the area famous. But metal prices alone do not account for the revitalization of McCreedy West Mine, located some 40 km north of the Greater City of Sudbury. Excellent planning using the best available equipment was a neces-sary ingredient, and Atlas Copco was with them all the way.

Footwall declineOne of the most important developments has been the driving of a footwall decline, from the 950 level to the 1,400 level, to access the nickel-rich Inter Main Deposit now being mined. This, in addition to early exploitation of the 700 Deposit, is one of the factors that enabled early revenue to be achieved. The ore-to-waste ratio now stands at 5:1, mine waste having been reduced from a high of 35 per cent during earlier mining operations.

In the ore zones, the ideal drive height is 3 m (10 ft), although this is sometimes in-creased to take the remaining ore. Cuts range up to 9.5 m (30 ft). Shotcrete pillars are used as temporary support for greater widths.

On current plans, 80 per cent of all mi-ning will occur in the Inter Main Deposit, where there are about a million tons of use-ful ore at 80 per cent extraction. The ore-body here is more discontinuous than usual, occurring in lenses, necessitating selective cut-and-fill, although there is expected to be some retreat bulk mining. Six horizons are currently being mined, which are split into different sections.

geologists rule With irregular geology, deciding where mi- ning should take place is not an easy task. Geologists are a big part of the operation here, and are on site every day. The miners don’t blast a face until a geologist has seen it and given approval.

The overall rock quality is good. It is ex- pected, however, that some faults and ore-body offsets in the Inter Main Zone will increase support measures.

Support is usually by 1.9 m (6 ft) rebar bolts and wire-mesh sheets, with cable bolt-ing on rare occasions. In the cut-and-fill areas, support pillars are constructed with shotcrete to enable maximum ore extrac-tion.

The 1.600 haulage level links the McCreedy West workings to the neighbouring Levack Mine. FNX Mining has reconditioned this area and, by agreement with CVRD/INCO, is able to hoist the McCreedy West ore via the Levack No. 2 Shaft to complement the MT5010 mine trucks on the main ramp.

In normal cut-and-fill mining, the crew consists of the jumbo operator, two miners on bolting, and one operating the Scooptram. There is an additional two-man crew on workplace safety using jacklegs and stopers Minetruck MT436B discharging at surface.

drills for bolting. In narrower workings, the crew is limited to two men.

Drilling and blasting

The Atlas Copco Rocket Boomer 282 was used on the 1,285 sub-level in the Inter Main Deposit, drilling 4.8 m (15 ft) holes with 5 m (16 ft) rods, with 60 holes in a face sec-tion measuring 6.4 m-wide x 4.6 m-high (21 ft x 15 ft). It takes between two hours and two hours 45 minutes to drill such a round.

Support in this area is provided by rebar rock bolts and wire mesh sheets using a scissor-lift access platform and handheld rock drills to install the bolts.

All rock drilling tools are from Atlas Copco Secoroc. The 45 mm diameter bits are ballistic type, using R32 drill rods. The same series of bits are used for all mining, because of their better wear life. Twice-daily deliveries of bits by Atlas Copco helps reduce inventories.

The bits are reground, and drill steel refur- bished, at the Atlas Copco workshop in Lively. Drill string components are sold on a stock replenishment basis, using an Atlas Copco storage container near the surface workshop.

Deliveries are made to a converted con-tainer supplied by Atlas Copco equipped with drill steels and bits stored in individual containers, specific to each driller. To avoid delays, deliveries are based on the consump-tion of previous weeks, rather than ordering when the need arises.

Maximizing haulage

Another major decision in the redevelopment of McCreedy West was how to optimize the haulage on the main ramp, which has an average grade of 18 per cent. Since it was the only main access, FNX Mining wanted to maximize its capacity by using trackless transport of the highest capacity.

To determine whether the Atlas Copco MT5010 could be used on the main ramp from the 1,400 level while ensuring the safety of vital service lines such as ventila-tion ducts, an existing 30 t mine truck was rigged to simulate its profile. A combination of surveying and trial runs then proved that limited slashing would achieve the required 4.6 m x 4.6 m (15 ft x 15 ft) clearance for the truck to be used.

The MT5010, which is the fastest truck in its class, takes between 45 minutes and one hour for the return trip, which is much

less than for the smaller trucks. In fact, the average cycle time on the MT5010 saves about one Canadian dollar/tonne, compared to using 30 t trucks.

It handles excellently and has fuel econ-omy with a really good range, enabling it to run all day on one tank of fuel. Its turning radius is excellent, and it gives a good ride with even power.

McCreedy West utilises a fleet of Atlas Copco Scooptram loaders comprising of ST1520s, ST7.5Zs, ST1020s, and ST710s. The mine also has three Atlas Copco Minetruck MT436B and three MT5010.

Scooptram duties include loading out from blasted faces, waste storage, rehandling stockpiles, and loading the Minetruck. When loading with the ST1520, the Z-bar linkage lifts higher than the ST8B, taking two buckets to load the MT436 B. The ST1520 is well liked because the operator has good visibility from the cab, which is roomy and comfortable. It also has exceptional lighting.

Safety is a big issue in mining operations, with mining companies being judged more and more by their safety performance. They are well aware that a low claim rate and a good accident record reduce costs. To assist in this, the new generation of Atlas Copco vehicles offers more ergonomically designed cabs with better operator comfort and visi-bility, improved drivetrains, lower emissions, easier servicing and maintenance, a range of other advances.

McCreedy Minetruck and Scooptram operators with their equipment.

Production Scooptram

Waste rock at McCreedy West comes prima-rily from development drives, and is stored in old drives or in mine-fill operations using Scooptram loaders with rammers, which are bolted on as necessary.

Depending on the circumstances, some Scooptram loaders are remotely operated for safety, such as when working through waste to a remote orebody.

Up to three Scooptram loaders can be operated by remote control although, due to the generally excellent ground conditions, more than one is rarely needed.

The 50-60,000 t of waste that had been generated by early development work was stockpiled on the surface, and is now being crushed and graded for return underground as fill material. All ore is carried by Scooptram loaders to either intermediate stockpiles under- ground, or for direct loading into the Mine-truck at the main ramp.

Maintenance contract

Atlas Copco provides dedicated product maintenance under a Gold Service Contract. Within this framework, a dedicated product support technician (PST) is permanently based at the mine, working closely with the mine maintenance foreman and technicians to ensure that all Atlas Copco equipment has maximum availability.

The contract includes a guarantee of 90 percent availability, vehicle condition audits, monitoring of parts inventory on site, and

training and liaison with mine staff on short- term servicing.

All underground maintenance require-ments are handled from a single workshop, but as McCreedy West is an access-ramp mine, most mobile equipment is brought to the surface for servicing. Services at 250-h, 500-h and 750-h are carried out on the pre-mises, but for 1000-h services, the equip-ment is taken back to Atlas Copco’s main workshop in Lively.

Additional initiatives

Besides a high level of service, other ini-tiatives contribute to profitability. These in-clude SPOT Boxes (Spare Parts On Time) – a suitable steel container or box supplied by Atlas Copco for each unit at the mine con- taining a stock of service parts. The content is predetermined according to experience of consumption and a technical review of wear and critical items, based on conditions of use and the consequences of failure.

SPOT Boxes are located in the surface workshop, but smaller SPOT boxes with frequently used parts can be situated on the rigs or elsewhere underground.

Larger boxes are fitted with forklift slots and lifting lugs for easy movement.

good start

All in all, McCreedy West’s new life is off to a good start. It has a new mining company, production is on target at 2,000 t/day, it is generating revenue, it has a first class safety record, all works are within government en-vironmental controls, and its prospects for reserves look bright. In addition, wherever FNX Mining goes, Atlas Copco is there to meet its needs.

The mine manager states that Atlas Copco service has been excellent. If there’s a pro-blem it gets solved, and things are dealt with at the right level. Atlas Copco Secoroc de-livery is also highly appreciated, and two deliveries a day means there is no waiting for anything the mine needs.
