摘　　要：结合老鸦岭尾矿库建库勘察资料,通过采用补充工程地质钻孔勘察及自然电场法、充电法、电流强度法、探地雷达法等6种地面物探勘察方法,查清了老鸦岭尾矿库南侧山体渗漏的主要原因以及尾矿水渗漏通道的平面位置、宽度及延深。老鸦岭尾矿库库区岩体破碎,裂隙发育,外围发育有溶洞,岩体有不同程度的溶蚀现象及溶蚀裂隙,节理裂隙与溶洞联通形成渗漏通道,导致尾矿水顺溶洞流出。根据本次渗漏成因及渗漏途径分析,提出采用修建临时集水池和钻孔帷幕灌浆的防渗漏治理方案。Combined with the investigation data of Laoyaling Tailings Reservoir,the main causes of mountain leakage on the south side of Laoyaling Tailings Reservoir and the plane position,width and extension of the leakage channel of tailing water were investigated by using six kinds of ground geophysical exploration methods,including supplementary engineering geological drilling investigation,natural electric field method,charging method,current intensity method and ground penetrating radar method.The rock mass in Laoyaling tailings reservoir area is broken,and the fractures are developed.There are caves in the periphery of the reservoir area.The rock mass in the reservoir area has different degrees of dissolution and dissolution fractures.Joint fractures and caves form leakage channels,resulting in tailings water flowing out of the cave.According to the analysis of leakage causes and leakage paths,a leakage prevention and treatment scheme was proposed by constructing temporary catchment and drilling curtain grouting.
