2 Autorock Drill Rig The Autorock drill rig has revolutionised stope support in South African platinum and gold mines since its introduction in Autorock drill rigs make rock bolting in narrow stopes a viable proposition by combining safe operation, accurate drilling and high output, all at a fraction of the capital and operating costs of fully mechanised rock bolting rigs. There are over 5000 Autorock rigs successfully operating on mines in the Platinum, Gold, and Coal industries in South Africa, with some in Russia and the USA. The principles of the Autorock rig are Rigid clamping of the rig between the hangingwall and footwall. Guided and powered thrust of the drill against the hangingwall. Remote operation. Modular construction, allowing easy maintenance and adaptability. the Autorock has been continuously improved and has been adapted for drilling in coal mines, in working places over 5m high and to a varietry of power sources, from the usual compressed air to hydropower, hydraulic power, water and electricity. Features that set the Autorock drill rig apart Ruggedness Minova has opted to offer robust, strong, withstand the adverse underground weight units that look good when new but do not last. Continuous improvement We work with our customers to constantly improve the Autorock drill rigs. The modular construction means that most improvments normal maintenance services. Some of the improvements we have introduced are: Fitting plastic protective sheaths to the cylinders, greatly reducing losses due to impact damage. Wide, lightweight wheels for operation on unstable surfaces, Drilling daylight the drill when it is clamped in postion) and can be drilled before a longer drill steel must be inserted). The combination of decreasing rock bolt installation times and making the rig safer and easier to use. The careful design and proven performance of the Autorock drill rig was recognised by the SABS Design Team and was one of the winners of the 2008 SABS Design Safety Features All Autorock drilling rigs allow remote operation from a distance of 3 6 m. The operator can stay under the safety of permanent support for most of the time. The allow for safe handling, with hands clear of moving parts and pinch points. 2

Quality assurance and sustainability Minova RSA manufactures Autorock drill rigs in its ISO 9001:2008 listed factory in Isando, Gauteng. The repair workshop in Rustenburg is also ISO 9001:2008 listed. Full risk assessments have been done for all rigs under numerous conditions, to 3

It is typically used for installing 6m cable anchors. stability and safety as well as a ladder for safe insertion of the cable anchors. Popular drills for use with this rig are the *Seco S25 and *CompAir Rocket. withdrawing the drill string. Giraffe Long Anchor Drilling Rig Features & Advantages Safe drilling in high working places. Safe erection of the unit. Safe, remote operation. Drill steel control with clamping and collaring devices. Accurate drilling. Used as access to install long anchors safely. hand when folded down. Cost effective in comparison with fully mecha nised rock bolters. Gully Rig tried and proven stope rigs. The rigs advantages include; One rig drilling for both stope face and gully support holes Safe and easy erection

5 Hydropowered Rig hydropower instead of compressed air. Water with pressure in the range MPa is used to power the drill. Minova has partnered with Novatek to develop hydropowered rock drills adapted for vertical drilling in narrow stopes. These while drilling twice as fast, with lower noise level and no discharge of oil. supply. Autorock hydropowered rigs are designed and manufactured to the applicable code of practice to ensure safety while using the high pressure water Rotary Drilling Rig This unit is used primarily in coal mines. It features aluminium Rotary Drilling Rig The higher thrust need for rotary drilling is provided by an customer s choice; typically a *Gopher or *Turbobolter, Suitable for use in coal mines. Accurate drilling. Light weight. Easily movable. *Hilti Electric Drill Rig electric powered rock drill. The thrust and clamping cylinders (less than 1 MPa) service water where no compressed air is available. *Hilti Electric Drill Rig Hilti electric driven drill less noise and vibration. air drills.

6 In-Stope Autorock and Resin Capsule Bolting System Advantages The drilling of the support hole and the complete installation of a steel rock bolt with resin capsules offers a cost effective, safe, simple and fast support solution. Speed of drilling and installation. Resin bolting with an Autorock ensures support installation discipline in that the rig is not moved away from the installation until the installation is 100% complete. the correct hole size, appropriate bolt and washer, shear pin and load indicator. Steel bolt shear pin and load indicator further offers visual proof of a successful installation giving management peace of mind. offering additional support to personnel. The drilling and complete installation of a 0.9m bolt in hard rock should take no longer than 6 minutes per installation. Minova Slim-hole Bolting System The system incorporates the following: width. Drilling of 28 mm diameter holes for use with coupled bolts or cable anchors where bushes, along with 19mm drill steel as a complete solution. Minova Slim-hole Bolting System Advantages Smaller holes give improved resin performance. Faster drilling. Lower cost of bolts and resin with the rock bolting components. Improved logistics and transport A dedicated support system eliminating sub standard practice. 6

7 Autorock Drill Rig Maintenance and Training Maintenance Planning Autorock rigs use galvanised steel for longer life and are constructed robustly protected cylinders. Under conditions of fair wear and tear, the Autorock Rig should be available in a mine pool so that rigs taken out of working places for maintenance and repair are immediately replaced and no drilling shifts are lost. Typically, about 10% of operating Rigs need to be available as spare rigs to keep all working places served. Maintenance Programme To ensure success of rock bolting programmes, Minova RSA offers maintenance services to suit customer maintenance system is essential to obtain the highest standards of availability, optimum performance and safe use of the Autorock drill rigs. 9001:2008 accredited repair workshops, in Johannesburg and Rustenburg. After maintenance each rig and every component is checked and tested before despatch. Repaired rigs are tested to the same standards as new rigs and are covered by a 3 month manufacture warranty. Rigs can be maintained/serviced with or without their rock drills. Statistics are collected on all maintenance work. Minova RSA can provide reports to mine management on repair and maintenance costs and cost drivers. The statistics are also used by Minova to guide its programme of continuously improving the Autorock rigs. For operators in areas where it is not feasible to return the rigs to Minova for maintenance, Minova will assist maintenance programmes. Training The correct training of the rig operators and all other personnel involved in the operation and management of the Autorock rigs is of critical importance to ensure the successful operation of the Autorock Rig and ultimately the rock bolting strategy. Minova RSA offers training packages to meet individual customer s needs. These include software to aid in selection of rigs and drilling accessories, training videos, Demonstrators Minova RSA provides the additional demonstrators to assist in introduction of monitoring. This service is recommended provided by means of a service contract, at an additional charge. 7
