Based on the "rich coal, poor oil, little gas" resource endowment conditions in China, coal is still the cornerstone of energy security. Abundant mine water generated by coal mining is a precious water resource, which can be used for mining area production and life by effective treatment. Accurate prediction of mine inflow is significant in mine drainage design and water resource proof. Taking Baorixile Surface Mine as an example, the hydrogeology and water filling conditions of the mine area are analyzed, and the mine inflow under the production condition in the future (2025) is predicted by using the hydrologic analogy method. Based on the relevant datas of the mine from 2001 to 2019, the multiple regression equation of the mine inflow and other related factors is established.The results show that the hydrologic analogy method has high prediction accuracy and is feasible. Finally, the predicted miner inflow value of Baorixile Surface Mine under the future production condition is 6375.02m3/d.The study provides reliable data support and technical support for safety production, drainage design and optimal allocation of water resources in mining areas.
