The products of Shijiazhuang Coal Mining Machinery Co., Ltd. in Hebei Province are also the birthplace of drilling rigs. Then in the decades of continuous development of tunnel drilling rigs, some manufacturers changed the torque and became their own models such as,, etc. Tunnel drilling rigs for coal mines are mainly used for water exploration, gas exploration, dustproofing, water injection, and various engineering holes and geological structure holes at different angles in coal mines. The drilling rig adopts mechanical transmission and hydraulic feed, and has the characteristics of small size, light weight, easy operation and maintenance. At present, the new column has been successfully applied to the deep-hole drilling rig for coal mines developed and produced by the company, which has greatly improved the safety of underground drilling operations in coal mines and provided technology for the safe production of coal mines in my country and to reduce the occurrence of emergencies such as gas explosions and water penetration.
