开孔直径：

Φ85

终孔直径：

Φ65

It has two types of drill frames: column frame and seat frame. Different drill frames can be selected according to the height and use of the coal tunnel. This type of drilling rig can push the mesh conduit into the hole while drilling, successfully solving the key problem of gas drainage in high-gas mines with unshaped or soft coal seams, so this type of drilling rig is also called Conduit drill or pipe jacking drill.
This type of drilling rig uses a high-pressure sealed drill pipe and a bottom hole motor to greatly improve the drilling capacity and avoid the strong torque force of the drill pipe's own weight, so this type of drilling rig is also called a bottom hole motor drilling rig
