Ground-oriented branch drilling technology refers to the drilling technology that vertically opens the hole from the ground and turns the target layer into a horizontal well at a certain angle. The coal mine is mostly used for the treatment of the ash area, and the horizontal directional drilling of the ground is used to construct a plurality of horizontal branch holes through a main hole of the ground to control the transformation range of the ash grouting to achieve the purpose of regional grouting transformation. Xipang shaft of Dongpang Mine used a combination of directional branching drilling along the coal seam and a small amount of underground drilling to complete the exploration of the damaged area of the shallow kiln, improved the scientific and technological level of water prevention and drainage and the efficiency of water exploration and drainage.
