Working Principle
The Kaishan KJ215 underground mining drilling rig operates on a top hammer hydraulic drilling principle. A diesel engine powers the hydraulic system, which drives the boom, feed, and rock drill. The hydraulic rock drill delivers high-frequency impact energy to the drill string, while the rotation unit turns the bit. Compressed air, supplied by an onboard or external compressor, flushes cuttings from the hole. The feed beam advances the drill string into the rock, and the boom positions the drill accurately. The operator controls all functions via joysticks from an ergonomic cabin, ensuring precise and efficient drilling. The rig’s articulated chassis and four-wheel drive enable tramming on rough underground roads.
