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 Drilling rigs are also called conduit drilling rigs or pipe jacking rigs.
This type of drilling rig uses a high-pressure sealed drill pipe and a bottom hole motor to greatly improve the drilling capacity (it avoids the strong torque force of the drilling rig twisting the drill pipe's own weight), so this type of drilling rig is also called a bottom hole motor drilling rig.
When this type of drilling rig is equipped with a high-pressure water generator and high-pressure sealed drill pipe, it can cut coal seams with low gas permeability, thereby improving the gas drainage efficiency and greatly shortening the drainage time. At the same time, this type of drilling rig can The drilling rig adopts a hydraulic transmission mechanism, which has the characteristics of large drilling capacity, fast speed, simple operation, stable and reliable operation, and convenient mobile installation.
