Sky reverse well drill pipes are mainly used in the construction of underground shafts, including ventilation shafts, material unloading shafts, various guide shafts (pressure pipelines, outlet shafts, surge tanks, elevator shafts), and various chutes (shafts, ore bins). According to the operating process of the Raise borer Machine, during the drilling of the guide hole, the drill rod is responsible for transmitting the downward thrust and torque generated by the main engine to the roller bit, enabling it to crush the rock through compaction; during the reaming process, Sky reverse well drill pipe is responsible for transmitting the upward pulling force and torque generated by the main engine to the reaming cutter head, allowing the rolling cutters on the cutter head to crush the rock wall through compaction.
