Working Principle
The Kaishan KM211 underground drilling rig operates on a hydraulic top hammer or DTH drilling principle. A diesel engine powers the hydraulic system, which drives the rotation unit and impact mechanism. The boom and feed system position the drill string accurately against the rock face. In top hammer mode, the rock drill delivers high-frequency impacts and rotation to the drill steel, transferring energy to the bit for efficient rock fragmentation. In DTH mode, a down-the-hole hammer is used, where compressed air (provided by a separate air compressor) drives the piston directly on the bit, ideal for hard rock and larger diameters. The feed system applies optimal thrust to maintain bit contact, while the flushing system removes cuttings from the hole. The articulated chassis and four-wheel drive allow the rig to tram efficiently between drilling sites. All functions are controlled from an ergonomic panel, ensuring precise and safe operation.
