Working Principle

The Kaishan KJ310 underground drilling rig operates on a hydraulic drilling principle. A powerful diesel engine drives the hydraulic pumps, which supply pressurized oil to the hydraulic motors and cylinders. The rotation unit, mounted on an articulated boom, rotates the drill string while the feed system applies thrust to the bit. For DTH drilling, compressed air is directed through the drill pipe to the down-the-hole hammer, which delivers high-frequency impacts to break rock. The cuttings are flushed out by the air stream. The rig's control system allows the operator to adjust rotation speed, feed force, and air volume to match rock conditions, ensuring optimal penetration rates and bit life. The articulated boom and four-wheel drive enable precise positioning and mobility in underground environments.
