Working Principle

The Kaishan KT15C operates on the down-the-hole (DTH) drilling principle, where a pneumatic hammer is positioned directly behind the drill bit. High-pressure air is delivered through the drill string to the hammer, causing the piston to strike the bit rapidly. This impact energy fractures the rock, while the rotation of the drill string ensures even wear and a round hole. The air also serves to flush cuttings out of the hole, keeping the bit clean and cool. The KT15C's powerful engine drives the on-board air compressor, which supplies the necessary air volume and pressure. The feed system applies optimal weight on bit for efficient penetration, and the crawler chassis allows precise positioning. This method is highly effective in hard rock formations, offering faster penetration rates and longer bit life compared to other drilling techniques.
