摘要
黄河流域矿产资源丰富,自然条件复杂,生态环境脆弱,历史遗留矿区的环境问题日益突出,生态环境亟待改善。以某历史遗留金矿氰渣库为例,通过污染成因分析,筛选出主要的环境隐患,并创新性提出通过采取完善环库截排洪设施、库面阻隔防渗及生态修复、下游建垂直防渗墙等一系列生态修复与风险管控措施,阻断尾矿库污染物扩散途径,降低尾矿库污染风险,技术的成功应用可为类似尾矿库环境整治提供参考。
The Yellow River Basin is rich in mineral resources,complex natural conditions and fragile ecological environment.The environmental problems of mining areas left over by history are increasingly prominent,and the ecological environment needs to be improved.In this paper,a historical cyanide residue reservoir of gold mine is taken as an example.Through the analysis of the causes of pollution,the main potential environmental hazards are screened out,and a series of innovative measures are proposed,such as improving the flood interception and drainage facilities around the pond,barrier and seepage prevention on the pond surface,ecological restoration of tailings pond,and building vertical cutoff wall at the downstream,to block the pollutant diffusion path of the tailings pond and reduce the pollution risk of the tailings pond.The implementation of the scheme can provide reference for the environmental improvement of similar tailings pond.
