Overview
KM211 hydraulic rock bolting rig is specially designed for the construction of rock bolts in the pipe seam of low tunnels; it can pass a section 2 m wide and 2.5 m high. It is qualified for anchoring operations in tunnels whose section extends to a width of over 2.5 m and a height of over 3 m.
Key highlights
- ✓Complete functions: the two-position advancing beam is equipped with a magazine holding 10 rock bolts; the optional protective netting module completes the processes of drilling, netting and installing rock bolts.
- ✓High safety: operators are protected by the ceiling, far away from the danger area.
- ✓High efficiency: the stepped piston used for the high-frequency rock drill improves impact-wave transmission, raises drilling speed and reduces drill-tool consumption.
- ✓The drill rig provides a good view for the operator; the articulated chassis of four-wheel drive ensures flexible, quick and safe driving in the narrow tunnel.
- ✓Considerable space and automatic functions let the driver concentrate on drilling in a safe, fast and accurate manner.
- ✓All the relevant parts are kept in good protection and are easy to maintain.
Applications: Rock-bolt construction in the pipe seam of low tunnels. · Anchoring operations in tunnels wider than 2.5 m and higher than 3 m. · Drilling, protective netting and rock-bolt installation with the optional netting module.

Recommended packages
Air compressor match
Underground jumbos run on the mine's electric/hydraulic supply — confirm voltage and water/air services at the heading. Where air is needed, match a KSDY electric compressor to the site power.
DTH hammer & bits
Kaishan underground rigs use premium hydraulic rock drills (Montabert HC50/HC95/HC109) for face and production drilling; the KSQ31 DTH model runs K-class hammers. Confirm rock drill model against your tunnel section.
