It is mainly used in the hole drilling of gas drainage in the coal with the hardness is less than 1.5. It can solve the problem of hole wall collapse, gas blowout, drill pipe sticking, drilling pipe holding or other unuarally drilling.

It is with the following features:

Fully hydraulic pole structure , includes four parts drilling rig, pump stations, crawler crane, operation panel, easy to go down and long distance transport.

With three pillars (national patent), the pillars are with a mechanical self -compensation function to stablilize the body, reliable support, cross belt work can be achieved.

Tracked self-propelled crane used to move the drilling rig and pump station, and reduce labor intensity and improve the efficiency of transition, you can slso do other auxiliary lifting operations.

Main hudraulic system with load sensing control system, low energy consumption, less heat; multi-way valve with pilot proportional control, lightweight, flexible, easy stepless control of drilling rigs; drilling system with anti-sticking(national patent), to reduce accidents hole; output and speed can be stepless adjustment according to the site needs.

Pump, valve, motor, traveling motor as well as the cooler are from the international brand, good reliability.

Spiral drill pipe drilling, the maximum speed can reach 600r/min.

When drilling hold or sticking, it can be reversed.
