Working Principle

The Kaishan KG920B operates on the down-the-hole (DTH) drilling principle, where a pneumatic hammer is positioned directly behind the drill bit. High-pressure air is supplied through the drill string to the hammer, which delivers rapid impacts to the bit, fracturing the rock. Simultaneously, the drill string rotates slowly, indexing the bit for even wear and efficient cutting. The cuttings are flushed out of the hole by the exhaust air, ensuring a clean hole. The rig's hydraulic system controls the feed force and rotation speed, optimizing drilling parameters for different rock types. The KG920B's diesel engine powers the hydraulic pumps and air compressor, providing the necessary energy for the drilling process. This method is highly efficient in hard rock formations, offering faster penetration rates compared to rotary drilling.
