1,Water well drilling rigs are divided into two types of drilling frames: column frame and frame.The drilling frame can be selected according to the height and usage of the coal tunnel.
2.The water well drilling rig can insert the mesh into the hole while drilling, and the water well drilling rig manufacturer solves the key problem of gas extraction from unformed soft coal seam high gas mines. Therefore this water well drilling rig is also called pipe drilling rig or pipeline drilling rig.
3, The water well drilling rigs choose high pressure sealed drill pipe and downhole motor, which can greatly improve the drilling capacity (avoiding the strong torque of the drilling rig and reversing the weight of the drill pipe), the water well drilling rigs are also called downhole motor drilling rigs.
4,The water well drilling rig can be equipped with high pressure water generator and high pressure sealed drill pipe to cut low permeability coal seam, improve the efficiency of gas extraction and greatly shorten the pumping time.
