In order to solve the problem that the drilling angle and direction could not be accurately controlled when the ordinary drilling rig was drilling in Zhenchengdi Mine, the No.ZYWL-6000DS directional drilling rig produced by China Coal Science and Industry Group Chongqing Research Institute Co., Ltd. was specially selected for construction. The advantages of directional drilling rig were introduced. The directional drilling rig was used to accurately explore and drain the water in the western Yicheng and Hongyuan Mine damage areas of the upper group of the south wing of Zhenchengdi Mine. According to the actual construction situation, the water accumulation area and the water exploration line were corrected to provide scientific and reliable geological data for the subsequent safe production of the mine.
