摘　　要：铜矿尾矿库是集中储存铜矿选矿废渣(尾矿渣)的人工构筑物,尾矿砂颗粒细小,积存量大,物相结构为松散堆积物,存在有害重金属、选矿药剂和废液,表面不能生长植被,风吹容易造成扬沙,污染大气、植被、水体、土壤。如防范措施不当,容易诱发滑坡、泥石流等次生地质灾害,存在重大环境安全隐患。尾矿库生态修复能够很好的解决以上问题,完成环境治理。The tailings pond of copper mine is an artificial structure for centralized storage of the ore dressing waste (tailings slag).The tailings sand has small particles,large amount of accumulation,loose phase structure,harmful heavy metals,ore dressing agents and waste liquid,and no vegetation can grow on the surface.The wind blowing is easy to cause sand lifting and pollute the atmosphere,vegetation,water body and soil.If the preventive measures are not appropriate,it is easy to induce secondary geological disasters such as landslides and debris flows,and there are major environmental security risks.The ecological restoration of tailings pond can solve the above problems and complete the environmental treatment.
