废弃稀土矿山的环境修复方案

Environmental Restoration Plan for Abandoned Rare Earth Mine

以江西赣县区某废弃稀土矿山开展的环境治理活动为例,介绍了废弃稀土矿山对矿区周边造成的环境问题,并根据废弃稀土矿山的现状,提出了采用物理措施、化学措施和生物措施相结合的矿区修复方案和以清淤为主,对堡坎进行生态复垦的河道治理方案。实践证明,矿山治理后,不仅减少了水土流失现象,降低了重金属进入地表水环境引起污染的风险,还改善了矿区地表水体的面貌,荒弃农田得以复垦,取得了较好的社会效益和环境效益。

Taking the comprehensive ecological improvement activities carried out by an abandoned rare earth mine in Ganxian district as an example,the paper introduces the serious damage caused by the abandoned rare earth mine to the surrounding environment of the mine area.According to the current situation of the abandoned rare earth mine,the paper puts forward a mine area restoration plan comprising physical measures,chemical measures and biological measures and rive control plan on ecological reclamation of retaining wall,giving priority to dredging.Practice has proved that it not only reduces the soil and water loss,but also reduces the risk of pollution caused by heavy metals entering the surface water environment after the comprehensive mine ecological improvement.Furthermore,it also improves the appearance of surface water bodies in the mine area,and the abandoned farmlands can be rehabilitated,achieving good social benefits and environmental benefits.
