Abstract Mine water damage was important hazard affecting the safe mining of Zhaogu No.1 Mine. In particular, the large water outburst caused by the structure conducting the deep aquifer was important form of mine water damage, which had the great impact on the safe production of the mine. Taking the No.10 injection hole in the ground regional control construction of No.15031 Face of Zhaogu No.1 Mine as an example, through the directional drilling exploration and control of F15 and DF102 faults, the combination of exploration and control was adopted to provide the basis for the structural exploration and control of floor reinforcement in Zhaogu field.
