摘　　要：为解决鱼洞河流域废弃煤矿酸性废水外排的问题,针对废弃煤矿酸性废水的成因(煤系地层硫化物、氧化环境、地下水及通道)及废弃煤矿的不同开采情况,分类施策、分部实施,通过对多处废弃煤矿治理经验的总结,提出了一套相对适合该区域实际情况的“追、堵、截、围”的煤矿废水“成因-源头式生态关水污水治理法”,即追索废弃煤矿的巷道分布、封堵关键段、截流地表水、采用帷幕灌浆抬升采空区的水位。该方法的基本原理是改变地表水进入采空区后直接外流的路径,采用巷道封堵、帷幕灌浆等手段隔绝废弃煤矿采空区的氧气,同时抬升地下水位,使顶板含水层逐步恢复到原有状态、使煤矿废水变成深部滞留水、使后续补给水从高位流出。雨季检验结果表明治理效果显著。In order to solve the problem of acid wastewater discharged from abandoned coal mines in the Yudong River basin,according to the cause of formation of acid wastewater(sulphide in coal measure stratum,oxidation environment,groundwater and channel)and different mining conditions of waste coal mine,classified measures and partial implementation are carried out,by summing up the treatment experience of many abandoned mines,puts forward a set of“Cause-source ecological water-shut-off wastewater treatment method”for coal mine wastewater,which is relatively suitable for the actual situation of the region,that is,tracing the distribution of the roadway in the abandoned coal mine,blocking the key section,intercepting the surface water,using curtain grouting to raise the water level in the goaf.The basic principle of this method is to change the path of direct outflow of surface water after entering goaf,to use the means of tunnel blocking and curtain grouting to isolate the oxygen in the goaf of the abandoned coal mine,and to raise the groundwater level,make the roof aquifer gradually restore to the original state,so that coal mine wastewater become into deep water retention,so that subsequent recharge water to flow out from a high position.The test results of rainy season show that the treatment effect is remarkable.
