In view of the drilling problems such as gas concentration exceeding the limit, hole collapse in soft coal seam and mines that need to improve gas drainage efficiency, the research and development team has conducted several experiments. The research and development need not be limited to small-sized gas drainage screen pipes such as 32mm and 36mm. The inner diameter of large hole drill pipe reaches 64mm, and 60mm gas drainage screen pipe can be used. The gas drainage screen pipe uses high density polyethylene, high toughness and extrusion resistance, thus improving gas drainage efficiency, it can reduce the cost of operation for you and improve the overall work efficiency.
