会东铅锌矿露天采场滑坡体的治理

在对会东铅锌矿露天采亏待同帮边坡临滑体区域进行工程地质调查的基础上，采用三维楔块体矢量分析法，对其稳定性了进行了分析，据此设计并采取了预应力长锚索支护、混凝土挡墙及防治水等加固治理措施。经几年的监测和矿山生产，尤其是雨季的考验，证明这坡治理是成功的。

Control and Treatment of Sliding Block in Open Pit Slope at Huidong Lead Zinc Mine

Based on the engineering geology survey of the area with critical sliding rock blocks in the south opencast slope at Huidong lead zinc mine,a stability analysis on the sliding blocks was carried out by the 3 dimension wedge vector analysis method.Accordingly,the reinforcement measures such as long pre stressed cable bolting,concrete stopping and water control were taken.Through monitoring for several years and testing by mining operation,especially in rain season,it was proved that the control and treatment of slope was successful.
