Working Principle
The Kaishan CDC-800 operates on the down-the-hole (DTH) drilling principle. A DTH hammer is attached to the drill string and lowered into the borehole. Compressed air is delivered through the drill pipe to the hammer, driving the piston to strike the drill bit at high frequency. The bit crushes rock into fragments, while the air flow continuously removes cuttings from the hole. The hydraulic top-drive rotates the drill string, ensuring even bit wear and straight hole trajectory. The feed system applies controlled thrust to maintain optimal contact between the bit and rock. The crawler undercarriage allows the rig to move and position accurately. This method is highly efficient in hard rock, offering fast penetration rates and reduced energy consumption compared to rotary drilling.
