Working Principle
The Kaishan KT11 open-pit DTH drilling rig operates on the principle of down-the-hole (DTH) drilling, where a pneumatic hammer is placed directly behind the drill bit. High-pressure air from an onboard or external compressor drives the hammer's piston, delivering rapid impacts to the bit while it rotates slowly. This combination of impact and rotation fractures rock efficiently. The rig's hydraulic system powers the rotary head, feed chain, and tramming motors. The operator controls the drilling process from an ergonomic panel, adjusting feed force and rotation speed to match rock conditions. Cuttings are flushed out of the hole by the exhaust air and captured by the dust collector. The KT11's track undercarriage allows precise positioning and stable drilling, making it a versatile solution for open-pit operations.
