Main Components
- Hydraulic rock drill
- Boom and feed beam
- Articulated chassis
- Diesel engine
- Hydraulic pumps and valves
- Control panel
- Water flushing system
- Undercarriage and wheels
Working Principle
The Kaishan KJ211 underground drill rig operates on a hydraulic top hammer drilling principle. A diesel engine drives the hydraulic pumps, which supply pressurized oil to the rock drill, boom, feed and tramming circuits. The rock drill impacts, rotates and feeds the drill string into the rock. Impact energy is generated by a piston striking the shank adapter, while rotation ensures even bit wear. The feed system pushes the drill string forward, and water is injected through the drill rods to flush cuttings out of the hole and cool the bit. The boom and feed beam allow the operator to position the drill accurately in any direction. The articulated chassis and four-wheel drive enable tramming on uneven underground roads. This combination of impact, rotation and feed delivers efficient drilling in medium to hard rock, with hole diameters from 45 mm to 76 mm and depths up to 100 m.
