Abstract The prevention and control of coal mine water damage was very important for coal mine safety mining. Combined with the geological conditions of Shouyang Kaiyuan Mining Industry of Yangquan Coal Group, the possible water damage in the future mining process were discussed. Firstly, the hydrogeological conditions of the mine field were analyzed, mainly the distribution of aquifer and aquifuge ; then we focused on the analysis of the water filling conditions of the mine ; finally, the possible water damage in the future mining process were discussed. The research results showed that the mining of No.3 coal seam in this mine would penetrate the upper sandstone fissure aquifer. The mining of No.9 coal seam was affected by the fissure water of the upper sandstone aquifer and the water accumulation in the goaf, which might form mine water inflow, but would not threaten the safety of the mine. Although No.15 coal seam was affected by karst water damage, it would not threaten mine safety.
