Based on the previous geological exploration data of Anzedengmaotong Coal Industry, combined with field investigation, the hydrogeological conditions and mine water filling factors were studied. The hydrogeological conditions of mine aquifer and aquifuge were identified, the mine water filling factors such as water filling source, water filling channel and water filling intensity were analyzed, and the mine hydrogeological types were divided. At the same time, the influence degree of water disaster on the mining of Anzedengmaotong Coal Industry in the next three years was evaluated, which provided the basis for the future mine water prevention and control work, and ensured the safe and efficient production of Anzedengmaotong Coal Industry.
