Wutongzhuang mine hydrogeological and geological conditions are extremely complex, there are water conduction fissures, faults, subsidence columns and other forms of water conduction. 182602 working surface after two phases of surface area treatment, the No. 2 coal substrate under the thin layer of tuff still exhibits strong water-rich, high water table, high water temperature characteristics. In view of this situation, the research and analysis were conducted, and after determining the formation mechanism of hydrological anomalies, the water coefficient of the aquifers of wild green, mountain fossil green and large lapis lazuli was finally reduced to below 0.1 MPa/m through regional management, underground drilling verification, reinforcement of the bottom plate slurry pipe, comprehensive physical investigation, curtain slurry, hydrophobic pressure reduction and other comprehensive water control measures, the safe mining was achieved.
