摘要
利用煤矸石填充塌陷区 ,对矿区土地复垦起到一定的积极作用 ,但煤矸石的淋溶渗滤液 ,已给地下水资源和土壤带来了极大的污染 .通过对淮南矿区煤矸石常规填埋法造成的危害及其污染途径进行讨论 ,提出对煤矸石进行卫生填埋 ,走综合治理与可持续发展相结合的道路 ,以恢复矿区生态环境的观点 .
There is some significance in reclamation by filling the depressions with coal gangue, but this method makes serious environment pollution, especially, to the groundwater and soil. The again pollution and pollution path of the simple gangue landfill are discussed here, and the article provides a new idea of filling depression areas with gangue by the sanitary landfill instead of simple landfill, and synthetic harnessing and sustainable development would be followed to deal with ecological environment problem in coal mining area.
