Working Principle

The Kaishan KG920A operates on the down-the-hole (DTH) drilling principle. A pneumatic hammer, attached to the drill string, is lowered into the hole and impacts the rock directly while rotating slowly. The hammer is powered by compressed air, which is supplied by a separate air compressor (not included). The rig's hydraulic system drives the rotary head, feed chain, and crawler tracks. The operator controls the drilling process from the cabin, adjusting feed force, rotation speed, and air volume to match rock conditions. As the hole deepens, the drill string is extended by adding rods. Cuttings are flushed out of the hole by the exhaust air and collected by the dust suppression system. This method achieves high penetration rates in hard rock with minimal deviation, making the KG920A ideal for blast hole and water well drilling.
