Yongan Mine's innovative water exploration drilling rig drilling tail

(Summary description)Underground drilling in coal mines is one of the important methods for mine water control. During drilling in the 3104 recovery area of ​​Yong'an Coal Mine, the tail and the drill pipe were often stuck in the tail of the water exploration rig during the drilling process, and the pipe clamp could not lock the tail. As a result, the drill pipe could not be replaced on site. To effectively improve this situation, the mine exploration and release team modified the tail of the drill, adding welding points on the surface of the tail, expanding the bearing surface of the tail, facilitating underground disassembly, effectively saving construction time and improving The construction progress was completed.
