河北承德某铁矿尾矿库副坝坡脚渗水治理
|
摘要
承德某铁矿尾矿库副坝坡脚出现了渗水现象,存在安全隐患。通过对隐患部位进行地质勘测和渗水原因分析,采取废石压坡、降低副坝坡度、设置排渗设施等综合措施,有效排除了安全隐患,保证了副坝安全,可为尾矿库类似安全隐患治理提供参考。
Water seepage phenomenon appears at the bottom of subsidiary dam slope of the tailings of an iron mine in Chengde City,the safety risks is significant. Through geological exploration and water seepage causes analysis,the integrated measures such as overburden the slope surface by waste rocks,reducing dam slope gradient and setting seepage drainage facilities are proposed. The applications results of the above technical measures show that safety risks of the bottom of subsidiary dam is eliminated,safety of the subsidiary dam is guaranteed,which can provide reliable reference for the treatment of safety risks of the similar tailings.
