Abstract: It is an engineering problem for coal resources mining under water-bearing quicksand stratum.Submergence accident will be caused by improper method.The water,quaternary quicksand aquifer,is considered to pose a threat to the mine mining by analyzing the hydrogeology characteristics of Baiyinchagan coal mine.According to the hydrogeology characteristics and the mine discharge prediction of this field,drainage measures of combining surface and underground were taken to ensure the safety of coal mining.
