Apart from a small number of mines using imported rig, drilling equipment drilling rigs for sale used in underground mines segmented mining law in our country has been in use to the end of the seventies of the last century developed YGZ-90 pneumatic drills. Due to the the domestic hydraulic technology, and the level of the hydraulic components is relatively backward, restricted the development and promotion of the full hydraulic mining jumbo. Currently, our research in the field of the full hydraulic mining jumbo has seriously lagged behind the development water well drill rigs of the world, not mature and reliable products for the mining selection. The drill rig is the subject of trackless mining equipment for deep hole or deep hole drilling large diameter blast holes. Both tracked and wheeled walking trackless drilling equipment. Rock breaking into the multi-function hydraulic mining Hole Drilling trolley high, large aperture Hole Drilling in soft rock underground rotary drill and suitable for hard rock aperture Hole Drilling Pressure submersible drilling rig. Energy a single rotary drill, the use of electrical energy, driven by hydraulic rock breaking, hole Drill movable air compressor you need electrical, hydraulic and pneumatic united drive.
