| 中文摘要: |
| 松宜地区煤炭开采历史悠久，是湖北省第二大煤炭生产基地， 2015年，响应国家政策，松宜地区煤矿全部停产关闭，关闭后煤矿遗留下的大面积采空区逐渐被地下水所充填，地下水位逐年增高，诱发了不同地层间的串层污染，地下水排出地表，也污染地表河流，给当地居民生活用水造成了严重威胁。本文在前在松宜地区地下水污染利用水封法治理的实践基础上，总结了水封法治理松宜地区关闭煤矿酸性废水机理，并归纳出不同关闭煤矿地下水污染“水封法 ”的适用条件，形成了一套“水封法 ”治理体系，可为具有相似条件的矿山酸性废水治理提供借鉴作用。 |
| 英文摘要: |
| Songzi-Yidu area has a long history of coal mining，and it is the second largest coal production base in Hubei Province. In the year of 2015，in response to national policies，all coal mines in Songzi-Yidu have been shut down. After the closure，the large areas of goaf left by coal mines were gradually filled with underground water，and the underground water level increased year by year，which induced cross-layer pollution between differ.ent strata. The groundwater has been discharged to the surface and polluted the surface rivers，posing a seriousthreat to the water supply of local residents. This paper is based on the practice of treating groundwater pollution bywater sealing method in Songzi-Yidu area，summarizes the mechanism of water sealing method in treating acid wastewater from closed coal mines in Songzi-Yidu area，and summarizes the application conditions of "water seal method" in different closed coal mine. A set of "water sealing method" treatment system has been formed，which can provide reference for the treatment of acid mine wastewater with similar conditions. |
