摘　　要：矿山开采引发的酸性矿井水(Acid mine drainage,AMD)污染是世界各国面临的重大环境难题。煤矿酸性废水污染是煤炭行业的主要污染问题之一。湖北省二叠系梁山组内各煤矿均已陆续停产闭坑。在煤矿的长期开采过程中,山体内部形成了大面积采空区,严重破坏了区内原始水文、工程、环境地质条件,致使在现有地质条件中产生了一系列新的环境问题,主要表现为废弃煤矿的酸性废水污染。针对松宜矿区陈家河流域地质环境背景、煤矿开采及酸性废水形成条件,对比百里荒井田,采用源头控制,打破传统的治理模式,通过煤矿酸性废水成因机理的研究,为今后湖北省恩施市及南方二叠系梁山组煤矿酸性废水综合预防起到重要示范和借鉴作用。Acid mine drainage(AMD)pollution caused by mining is a major environmental problem faced by countries around the world.Coal mine acid wastewater pollution is one of the main pollution problems in the coal industry.All coal mines in the Permian Liangshan Formation in Hubei Province have been shut down and closed one after another.In the long-term mining process of coal mines,a large area of goaf has been formed in the mountain,which has seriously damaged the original hydrological,engineering and environmental geological condi-tions in the area,resulting in a series of new environmental problems in the existing geological conditions,mainly manifested in the acid wastewater pollution of abandoned coal mines.In view of the geological environment background,coal mining and acid wastewater formation conditions in the Chenjia River Basin in Songyi mining area,compared with the Baili barren well field,the source control was adopted,the traditional treatment mode was broken,and the research on the genesis mechanism of coal mine acid wastewater in coal mines played an important demonstration and reference role in the future for the comprehensive prevention of acid wastewater in Enshi City,Hubei Province and the Liangshan Formation of the Southern Permian.
