This series of rigs are capable of large diameter rotary drilling with borehole depth from 6000 to 1500m, and also capable for precise directional drilling operations with borehole depths of up to 1000m by using a downhole motor. The rigs are widely utilized in highly-precise directional drilling operations for gas drainage, water detection/drainage, grout injection, exploration of geological structure, detection of seam thickness, water injection in seam, etc.
This series of rigs can be used for directional drilling operations with a downhole motor, for rotary drilling and for other drilling operations as well. The rig is suitable to accomplish highly-precise directional drilling operations in underground coal mines, such as gas drainage, water detection/drainage, exploration of geological structure, detection of seam thickness, water injection in seam and grout injection in roof.
