The Xinfang Group Huada Fengda coal-bearing formations are the Upper Carboniferous Taiyuan Formation and the Lower Second Diego Shanxi Formation. The main aquifer in the mine is Tertiary conglomerate, Xujiazhuang limestone and Ordovician limestone. The mine water inflow is about 12.0m3 min, which is a mine with complex hydrogeological conditions. The main coal seam is a four-layer coal with a thickness of 6.5m. The main aquifer affected by the fourth coal mining is the Tertiary conglomerate aquifer. To identify the mining area
