SICOMINES铜钴矿含尾砂高大边坡稳定性分析及治理思路

Stability Analysis and Management Ideas of Tailing-containing High Slopes in SICOMINES Copper-cobalt Mine

刚果(金)SICOMINES铜钴矿M坑北部上部局部边坡处于不稳定状态,可能存在滑坡风险。本文采用二维极限平衡分析方法,对北部含尾砂高大边坡稳定性进行了边坡稳定性计算和分析,提出了整体边坡角不应大于31°的优化建议,并为后续边坡治理提供了参考。

Some slopes in the upper part of the northern part of pit M of SICOMINES copper-cobalt mine in Congo(DRC)are in an unstable state,and there may be a risk of landslides.This paper adopts two-dimensional limit equilibrium analysis method to calculate and analyze the stability of the tailing-containing high slopes in the northern part,and puts forward the optimization suggestion that the overall slope angle should not be greater than 31°,which provides a reference for the subsequent slope management.
