Φ50

钻孔倾角：

-90～+90

输出转速：

80/170

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 pipe into the hole while drilling, successfully solving the key problem of gas drainage for high-gas mines with unshaped or soft coal seams, so this type of drilling rig is also called Used as conduit drilling rig or pipe jacking drilling rig.
This type of drilling rig uses high-pressure sealed drill pipe and bottom hole motor to greatly improve the drilling capacity (avoiding the strong torque force of the drilling rig twisting the drill pipe's own weight, so this type of drilling rig is also called bottom hole motor drilling rig< br/> > Item
