Atlas Copco Rock ReinforcementOngoing development of faster, safer and more exotic tunnelling techniques places a constant pressure on manufacturers to provide more effi cient rock support solutions which will help the shortening of cycle time. As ground conditions get more and more demanding, emphasis is placed on fl exible and intelligent support systems in which rock and soil reinforcement is expected to contribute to the productivity and safety of the operation. The trend has been to provide rock support and reinforcement systems that are easy to install, assure effi ciency and provide safety.
For the last 25 years, Atlas Copco has been offering the SwellexTM concept as a unique, safe and reliable system of rock support. As the market leader in underground rock excavation technology, Atlas Copco has also been developing safer and more effi cient rock reinforcement products such as the Manganese line rock bolts, which are manufactured from a special type of steel. Another development is the Swellex Premium line of rock bolts, for use where high yield load and stiffness are expected from the reinforce-ment system.
When Atlas Copco bought MAI in 2001, the rock reinforcement center moved to Feistritz/Drau, Austria. This acquisition made it possible to introduce a whole new range of products for Atlas Copco customers, the MAI SDATM anchors, which are now being developed for mechanized installation by both surface and underground drill rigs, creating fresh applications in rock and soil reinforcement.
Atlas Copcos Rock Reinforcement Center in Austria brings together the skills necessary for the develop-ment of superior rock reinforcement products to serve the tunnelling, mining and construction industries worldwide. The combined product portfolio includes Swellex rock bolts and MAI SDA anchors with all necessary accessories.
The strategy to act as The professional supplier of specifi c and complete solutions in rock and soil re-inforcement has paid off, and the effort to invent and commit ourselves to more productive solutions is stronger than ever.

Quality assurance means safety
Quality assurance for safer reinforcementSafety in a mine is not something Atlas Copco, takes lightly. Its a major issue for those who own and those who work there. A minor fault in a rein-forcement bolt may prove fatal. Thats why Atlas Copco rock bolts are rigorously tested to en-sure the best possible quality and reliability. In fact our Quality assurance system is the most compre-hensive on the rock reinforcement market today.
ISO - Management systems that work harderISO standards represent the best management systems for quality and environmental issues. Its therefore not surprising that Atlas Copco is ISO 9001 certified to systematically control overall quality. The company is also ISO 14001 certi-fied to minimise the environmental impact of the company. These are applied at every Atlas Copco manufacturing plant as well as every distribution and customer centre. They basically form the basis of the companys Quality Assurance program.
Quality control starts at the suppliers...ISO certification is the prerequisite for every Atlas Copco supplier. Whether its rods for MAI self drilling anchors or steel profiles for Swellex, suppliers have to follow our specified tolerances. To ensure their quality, we test every batch for deviations and register the results.
...and ends at the clientsTo confirm that finished bolts can withstand the working pressures stipulated, we carry out destruc-tive tests on samples of Swellex bolts and MAI self-drilling anchors. And if this is not enough, eve-ry bolt is stamped with its own number. So should a problem arise, the cause can be efficiently traced back and action can be taken promptly to rectify it.
In accordance with ISO9001, Atlas Copco has developed comprehensive instruction and training material to enable end-users to install bolts and anchors correctly and safely.

Quality assurance means safety
MAI SDA self-drilling anchorsThere are two important quality parameters for a MAI self-drilling anchor. Firstly, that anchors can withstand the stipulated working pressure and, secondly, that couplings and bits can be easily threaded.
Ultimate load tests are carried out on 1 in 200 of the manufactured anchors. A special test bench pulls these anchors until they break and the results are monitored. Should an anchor fall short of the given tolerances, production is stopped and the fault is rectified.
Atlas Copco MAI also offers a hot dip galvanized MAI self-drilling anchor. This galvanised layer has to be the right thickness for the couplings and bits to be threaded on properly.
Again, a sample of anchors is removed from the production line during each shift and the thickness of the galvanisation is tested and registered.
Swellex rock boltsThis expandable rock bolt is more complex to manufacture than a MAI SDA. The steel profile is pressed into shape and a bushing is welded on the open end-piece. As pressurised water is used to install a Swellex bolt in the hole, leakages are not wanted. Thats why each and every bolt is tested for leakage as part of the production process. This unique operation is augmented by destructive expansion tests where 1 bolt in 200 is pressurised to the limit to ensure that the batch can withstand a minimum a working pressure of 300 bar.
In effect, one sample bolt is removed at the begin-ning of each shift and one when a new batch of steel profiles is used. This means that 1% of all bolts are sacrificed in the name of quality assur-ance.
We, at Atlas Copco, believe that assuring quality throughout the complete supply and distribution chains is the best way of ensuring the highest level of safety for our customers.

The Atlas Copco MAI SDA is a unique bolting solution for unstable ground conditions such as sand, gravel, silt, and clays, and in soft to medium fractured rock formations.
For projects facing such ground conditions, MAI SDA self-drilling anchors should be considered as the main productivity solution.
Atlas Copco Swellex rock bolts, which are quickly and safely installed in rock not tending to collapse, gives immediate support, speeding up operations and boosting revenues. Over the past two decades, the Swellex rock bolting solution has become world famous as the simplest, fastest and most reliable rock reinforcement technology avail-able.
MAI SDA anchors versus Swellex bolts
MAI SDA installation The MAI SDA solution is designed for optimized installation, tailored to the projects needs. By drilling a hole in collapsing soil or loose rock, with a sacrifi cial drill bit and a hollow rod, and after the drilling operation injecting grout into the hollow rod and surrounding cavity, makes it a top produc-tivity solution.
Swellex installationThe Swellex bolt is a folded steel tube, which is inserted into a pre-drilled hole in the rock. Water is blasted into the tube at high pressure, blowing out the fold and expanding the tube into the exact shape of the hole, adapting to every irregularity.
Bolt installation takes less than 30 seconds, and provides full and immediate support along the entire hole length, in ground conditions ranging from the hardest rock to clay even non-cohesive material.

Foundation with micropilesThe application circle below displays the three most important areas and industries where the MAI SDA is best utilized
Slope stabilizationIs used to stabilise mostly unstable rock/soil for-mations which are normally benched prior to the installation of the "soil nails". The unconsolidated or weathered ground conditions favour the tech-nique of Self Drilling Hollow Core Anchors (SDA) for the fast and simple method of installation com-pared to the traditional methods of cased boreholes and inserting of a suitable tendon.
Foundations with micropilesMAI SDA micro piles can be defi ned as small diameter replacements, drilled piles, composed of injected grout with the MAI SDA anchor rod as
steel reinforcement to resist the design load.
The MAI SDA micro piles can be installed in sites with limited headroom, restricted access capability with light drilling equipment which have low noise and vibration and require minimal site preparation. MAI SDA can be installed successfully into most ground conditions including rock and is suitable for tension and compression loads. The big advan-tage is the combined drilling and grouting making high piling outputs possible.
TunnellingMAI SDA anchors are the most economical solution for the reinforcement of the tunnel cir-cumference and advance roof support for tunnel excavation in overburden and soft factured rock conditions.

MAI SDA self-drilling anchors
The selection of drill bitsA successful installation of the self-drilling anchor system (SDA) depends on the selection of the most suitable drill bit. Compared to conventional drill bit types offered globally for maximum stand-ing performance for rock or soil, the criteria for SDA drill bits are defined by consideration of the following factors:
High quality for a limited service life Installed MAI SDA length Geology Geometry
High quality for a limited service lifeSince the nature of the drill bit is sacrificial, the maximum stand up time is that required to install one anchor.
MAI SDA installed lengthDepending on the SDA applications, standard drilling depths would be in the range of:
Tunneling (SDA): 4-10 m Soil and Rock Nailing (SRN): 8-20 m (30 m) Micro Injection Piling (MIP): 10-20 m Temporary Support Anchors (TSA): 15-30 m
GeologyThe unique MAI Anchor system was developed over the years for the sole purpose of the drill bit to penetrate fractured and weathered rock and unconsolidated soil formations. Constantly vary-ing conditions, from clay to gravel and boulders, as well as sand and rock, require a multi-functional bit design that provides:
Optimum cutting ability in mixed ground conditions
Adaptable flushing and grouting performance Maximum penetration speed
GeometryProject design for external skin friction demands a selection of various drill bit diameters. In order to maintain the functionality of the system, the fol-lowing range of diameters should be selected for the different anchor dimensions.
The sacrificial drill bit is the most crucial part of the anchoring system, and is responsible for the productivity of the installation. Atlas Copco MAI maintains a large range of drill bits to suit the changing demands of geology encountered on different projects. In order to improve on perform-ance and cost efficiency, data is collected from projects around the world, and incorporated into the design with the aim to improve penetration rate and bit quality, and to reduce manufacturing costs.

MAI SDA self-drilling anchors
Hollow anchor rodsThe anchor rod features a hollow bore for fl ush-ing, or simultaneous drilling and grouting, and has a left-hand rope thread for connection to standard drill tooling.
It is manufactured from API standard heavy wall-ing steel tubing, cold rolled to form a standard ISO rope thread profi le. The rolling process refi nes the grain structure of the steel, increasing the yield strength, and producing a durable drill rod suit-able for a range of applications. The standard rope thread of the anchor rod produces an excellent bond between the rod and grout, as well as ena-bling connection to all Atlas Copco Boomer face drilling rigs and Atlas Copco Roc surface drill rigs, and use with a wide range of drill steel accessories.
The anchor rod is produced in 12 m lengths and then cut to size depending on customer require-ments. Standard delivery lengths are 1 m, 2 m, 3 m, 4 m and 6 m. Recommended maximum rod lengths depend on diameter and can be up to 6 m. Additional lengths up to 12 m are available on request.
Extension couplingsThe coupling features a patented design that enables direct end-to-end energy transmission between each bar, reducing losses and ensuring maximum percussive energy at the drill bit.
To enable the correct seating of each bar within the coupler, all bars are chamfered with precision to enable the bar ends to have contact.

MAI SDA self-drilling anchors
Bearing platesThe bearing plates are formed steel plates with a centre hole, allowing articulation of seven degrees in all directions.
All functional parts are constantly tested, in line with the Atlas Copco rigorous quality assurance policy.
Hexagonal nutsThe hexagonal nut is manufactured with cham-fered edges on both ends from high precision steel, and tempered to meet any stringent demands of the anchor specifi cations and the daily operations of underground works.
All nuts exceed the ultimate strength of the bar by 20%.
Galvanized anchorsCorrosion is a very complex process, and corro-sion rates are very hard to predict accurately. How-ever, predictive methods can be helpful to evaluate the need for corrosion protected rock bolts. For this reason Atlas Copco has developed a hot dip galvanizing corrosion protection. The full range of SDA bars with couplings and nuts are available with this corrosion protection.

length between soil/rock and boltImprovement of corrosion protection providing
longer service life
The option to introduce high speed stabilization with SDA versus cased borehole drilling solutions
No separate drilling equipment needed, same crew
No subcontractors and no investments in capital equipment
Providing technology to introduce high speed cur-ing grout formulas
Back pressures during grouting can be absorbed by drill feed and boomer, thus enabling higher grout pressures, thus allowing lower W/C factors reducing the curing time, providing earlier load bearing of SDA resulting in a reduced excava tion cycle time.
MAI SDA installation methods
Semi-mechanized installationThe anchoring or bolting industry has a demand for increasing the effi ciency and quality of the installation of bolts. In addition increased safety by minimizing work in unprotected areas are becom-ing more important to contractors when installing bolts in diffi cult rock/soil conditions.
A change from the conventional post grouting method to a semi-mechanized installation method using an IRIA (Integrated Rotary Injection Adapt-er) method provides an adaptable installation proc-ess, which offers an improved solution and as such added value to the Customer:
SDA installation becomes one work cycle per-formed only by the drill feed
No additional work cycle for post grouting Reduced operation cost for additional equipment
(working platforms etc.)Better adjustment of the installation process in
respect with the changing geologyFlexible selection and adjustment of fl ush media
as needed (water, air or grout)
1. Drilling with water fl ushing.
2. Adding a coupling to extend the anchor with another rod.
3. Connecting to grout pump and inject the mixed grout.
4. Once grout has hardened, the anchor is perfectly installed.

Centralizer A centralizer is available for specialist applica-tions. For general use the centralizer is not re-quired as it snags during rotation and interferes with grout circulation in the borehole. The use of a centralizer does not guarantee comprehensive grout cover along the length of the bar as it's is im-possible to control the grout within the borehole.
Coupling boxesManufactured from thick-wall steel which is machined and case hardened. Coupling boxes are used at high wear locations, typically just below the hammer drive. A locking torque is normally applied to the coupling box at the permanent joint, to avoid release when additional anchor bars are added.
All the coupling boxes are supplied with a bridge to act as a centre stop.
When a step down (reducer) drive arrangement is used i.e. R38 shank to drive to install R32 anchor bar, a locking torque should be applied at the R38 end to prevent the R32 bar climbing into the R38 chamber.
Step up drive arrangements are not recommended as the additional torque overloads the smaller drive.
ShanksRotary percussion is the preferred method of in-stallation. Either hydraulic or air hammer is suit-able. To transfer the rotation and percussion from the hammer to the bar's system there is a need for the special tool named shank adapter. Atlas Copco is providing a full range of different shank adapt-ers for different hammers.

Swellex rock bolts
Since its introduction 25 years ago, the Swellex rock bolting system has gained wide recognition in mining and tunnelling works. It is a unique rock bolt, as it is made out of a welded tube folded on itself and sealed at one extremity. It is re-expanded using a high pressure water flow provided by a spe-cial pump and adapter. The bolt is expanded inside a borehole drilled into the excavation wall, why the installation process is easy and very similar as other rock bolts, making Swellex accessible to all opera-tors. The speed and quality of installation and the exten-sive application range have solved support problems and increased profitability for contractors and mine operators all over the world. As mine and tunnel safety requirements have become more stringent, the prompt, reliable and versatile support available with Swellex rock bolts has made them the best for most problem solving, and one of the best for rock reinforcement in general.Through a process of continuous improvement, Atlas Copco has refined Swellex to offer the most versatile portfolio of rock bolts available on the market. Swellex rock bolts from Atlas Copco ex-ist in two typical versions, one being the Swellex Premium line, a relatively stiff rock bolt for tunnel-ling and mining in moderate stress conditions, and the other one called the Swellex Manganese line, a highly deformable rock bolt for large rock deforma-tion situations.Another improvement is the line of corrosion protected Swellex. From the well accepted rubber bitumen coating to the new Plasticoated Swellex for highly corrosive environments, Atlas Copco cov-ers all demands for corrosion protection and long life rock bolts. And again, for special applications like hangers and deep reinforcement, Atlas Copco has perfected versions of Swellex to perform these tasks with the same easy system. With the Swellex Hanger Pm24H, the operator can install its serv-ice hanger in the same reinforcement operation as the primary support. The Connectable Pm24C is a modern replacement to medium length cable bolts, with high productivity, quality control and safety components.
30
Swellex featuresThe Swellex rock bolt is made out of a welded steel tube folded on itself and sealed at one extrem-ity, while the other extremity is set with a special head bushing used for inflation and retaining of the face plates typically used in rock bolting.
The expansion of the bolt, inside the drilled bore-hole, creates a friction and interlocking anchor, which provides instant reinforcement and support.
Swellex rock bolts can be considered as a full column support as they provide reinforcement and support on the whole length of the borehole, what-ever happens at the collar area. Due to its unique anchorage mechanism, the Swellex bolt can adapt to a wide variety of ground conditions and provide good to excellent anchor-age capacity in most rock types. The steel profile can also adapt to shear movements, and in softer materials the Swellex bolt accommodates large shear displacements without failure.
The simplicity of the system can explain its per-formance. The operator simply drills a hole in the rock, inserts the bolt and then inflates it to a pre-determined pressure using a dedicated inflation system. The pump stops when reaching the rec-ommended inflation pressure that guarantees the quality of the installation.
Swellex rock bolts can easily be pull tested. In fact, a Swellex rock bolt has the easiest pull test operation of any rock bolt type.
As the anchorage principle of Swellex is a tight interlock with the asperities of the borehole sur-face, corrosion can develop if the environment is prone to corrosion processes. In order to provide a solution for long term reinforcement, and handle particularly aggressive situations, Atlas Copco provides two versions of protected Swellex bolts, the Bitumen coated Swellex and the Plastic coated Swellex. These two products extend the normal life of a Swellex by many years.

ApplicationsSwellex rock bolts are extremely versatile and can be used in a variety of excavation, from tunneling to mining. A very typical application in tunneling is to use Swellex as pattern bolts to support, rein-force or consolidate the periphery of an excava-tion. The density of bolting depends of the size of the excavation and the self-supporting qualities of the rock mass. In mining, common applications

Roof boltingRoof bolting
like roof and hanging wall bolting have adopted Swellex as a rapid and performing stabilisation de-vice. Because Swellex is expanded inside a bore-hole smaller than the folded tube circumference, it is not sensitive to hole diameter, rock quality or water conditions and provides a good anchorage capacity in most tunneling and mining conditions.

Swellex rock bolts
Atlas Copco offers a versatile portfolio of rock bolts that provides reinforcement solutions for ground conditions varying from easy to very dif-fi cult. With three typical capacity ranges, at 120 kN, 160 kN and 240 kN, the Swellex rock bolts can be used in most reinforcement and support ap-plications. They can also be used either in mines or in civil engineering applications and their specifi c mechanical properties will provide the needed safety and performance. Selection of a rock bolt is usually done during the design phase of an excava-tion, and is the prerogative of the design engineer as it involves geological and structural knowledge and engineering computation. However, the fol-lowing sections can help understand the specifi c mechanical properties of the Swellex bolts and ease the selection process.
Premium lineThe Premium line is a typical tunnelling bolt, with a high yield load and good deformability. It pro-vides a competitive strength combined with the classic Swellex system performance. Pm rock bolts can also be used in mining when low to medium stress conditions require a stiff Swellex rock bolt with a high yield load. However, Pm line Swellex are deformable enough to provide a safe behaviour in rising stress conditions and can be used in most typical mining environments.
Manganese lineThe Manganese line was developed to suit large stress changes occuring in some mining and tun-neling projects. Made from a very specifi c steel type, Mn rock bolts receive a heat treatment to im-prove their mechanical properties. Manganese line Swellex rock bolts have a unique yielding behav-iour that can be matched only with the proper steel manufacturing. As a result, they provide a high ultimate load and a large deformation capability. Because of these outstanding mechanical proper-ties and the quality assurance associated with the Swellex system, the Manganese line has been amining success.

Plastic coatedPlastic coated Swellex is providing its long term corrosion protection through a thick plastic coating that is impervious to water and current. The dam-age resistant coating is very effective in very corro-sive environments and its resistance and effective-ness is proven over years of application in highly acidic conditions.
Swellex Pm24C a connectable boltFurther to the typical pattern rock bolting appli-cation, the Swellex Pm24C offers the possibility of deeper reinforcement without grouting opera-tion. The Swellex Pm24C is a connectable rock bolt, which consists of individual sections that are joined together via R thread connections. The required bolt length is achieved by adding one or more sections. Swellex Pm24C bolts are very competitive against short and medium length cable bolts.
A Swellex connectable rock bolt
Swellex Pm24H a hangerThe Swellex Pm24H is a new generation of hanger that provides a high anchorage capacity hanger with a fl anged head with a female M36 thread. The rock bolt has a static axial load carrying capacity of 200 kN and is designed for hanging services. The fi nal hanging capacity is determined by the eye bolt capacity. After the Pm24H bolt has been installed by using an infl ation adapter, a forged eye bolt with M36 thread is screwed on. Utilities can then be suspended directly from the eye bolt. As the Pm24H is not designed for excentric loading, the design load should always be coaxial to the bolt profi le, and the bolts installed as vertical as pos-sible. The end sleeve should be inside the borehole in rock and shotcrete. Swellex Pm24H can be installed using standard Swellex installation equipment combined with a small infl ation adapter.

Swellex installation methods
Manual installation
Mechanized installation
Rock bolting for mining and tunnelling has reached a phase of performance never attained in the past. While spot bolting is still used to stabilize individual blocks in roofs and walls of excavations, the trend is to use rock bolting as a systematic mean to provide a global reinforcement mechanism that will allow longer and safer use of underground excavations.
Along these changes, mechanization of rock bolt-ing has become a preferred way for many tunnel and mining operators. Not only does a mechanized installation provide a higher productivity, it also helps to maintain a safer working environment. However, since the demand for manually installed rock bolts is still high, support systems must be fl exible and allow manual as well as mechanized installation operations.
Over the last decade, it has been recognized that the installation operation is a critical step in as-suring the effectiveness of a rock support system. If not properly installed, the best rock bolt will behave poorly and provide a false sense of security that is detrimental to the reinforcement purpose. Better bolting operation and quality control of the raw materials is now a basic component of a good reinforcement system.

Swellex rock bolts
Swellex face platesFace plates are used to create a local surface sup-port around the borehole collar area. With point load anchor bolts, the plate is used to transfer the displacement of the rock mass into the rock bolt, without it no load transfer can take place. Full col-umn support like grouted bolts and friction bolts need a face plate to maintain rock mass loading on the area of the collar only as most of the loading occurs along the bolt body. Face plates are used to maintain local roof stability, to prevent keyblock movement, and retain surface support like mesh.
The Swellex face plates are manufactured from high quality steels, and meet or exceed the prop-erties stated in the individual specifications. All face plates are designed, manufactured and tested according to ASTM F432-95 standards.The face plates capacities are designed to meet the custom-ers requirements.
Hard rock conditionsIn hard rock, where the anchorage capacity is often exceeding 200 kN per metre of anchorage length, the load that is transferred on to the face plate is rarely more than 50 kN, as friction on the profile takes over most of the loading from the rock mass.
Hanging featureMost face plates types can be specified with a hole or notch to be used to hang light and non-vibrating or oscillating services. The suffix L is then added to the plate description to indicate the presence of such a hole or notch. This added feature does not reduce strength specifications, but it should not be attempted to hang heavy or vibrating services as the long term capacity of the rock bolt could be dramatically reduced.
Face plates with lance Face plates with a bent corner
Soft ground conditionsIn softer ground conditions and broken rock masses, the load transferred onto the plate is much higher as the rock mass close to the borehole collar tends to yield more freely and exert a direct load-ing over the plates.
Accordingly, the high strength face plates are de-signed for high convergence conditions and poten-tially dynamic conditions. In low stress or loading conditions, regular strength face plates can be used efficiently and safely as proven by years of usage in the tunneling and mining industries.
