The mine water generated during coal mining is a crucial environmental factor that needs to be addressed for coal mines to achieve clean and green production methods. To reduce the generation and discharge of mine water and promote the green transformation of mining area production, a coal mine in the southern Hebei mining area implemented measures such as water-preserving mining, filtration of mined-out areas, a combination of underground and surface treatment, and comprehensive utilization of mine water, achieving significant economic and ecological benefits. Through water-preserving mining, the mine reduced the annual generation of mine water by approximately 1.3 million cubic meters; through filtration and utilization of mined-out areas, the annual discharge was reduced by 510,000 cubic meters; and through mining area production, greening, greening of waste rock piles, and irrigation outside the mining area, the comprehensive utilization rate of mine water was significantly increased. By reducing the amount of mine water at its source, implementing efficient treatment, the mine has protected the underground water resources of the minefield and the ecological environment of the mining area, promoting the transformation towards clean and green production methods in mining.
