A majority of coal mines, located in arid and semi-arid areas of western China, are facing the challenges among mine water resource supply, drainage and ecological environment. Numerical models of groundwater movement in aquifers are built in Suancigou Coal Mine, which are based on hydrogeological conditions analysis and characterization of mine water filling factors. According to the specific requirement of mine water users for water quantity and quality, mine water is treated in tertiary (sewage) treatment. The optimized hydraulic-economic management model is analyzed by control, treatment, utilization, recharge and ecological environmental protection of mine water. The model solves the mine water resource problems in Suancigou Coal Mine, and supports it to realize the sustainable development and utilization of groundwater resources, which would contribute to tremendous economic benefits.
