| 边坡稳定性直接关系到露天矿山的安全开采，为分析露天矿采场边坡稳定性，本文以西藏某露天铜矿采场高陡边坡为研究对象，根据矿山边坡现状、边坡岩体结构和结构面发育特征等因素对现状边坡进行地质分区，通过岩石室内物理力学试验获得坡体岩石物理力学参数，利用两种不同的极限平衡法方法计算各分区在3种荷载工况下现状边坡稳定性系数。计算结果显示，该各地质分区现状边坡所有荷载组合下的安全系数均满足规范要求，可为矿山安全生产提供参考。 |

| The slope stability is directly related to the safe mining of open-pit mines. In order to analyze the slope stability of open-pit mines， this paper takes the high and steep slope of an open-pit copper mine in Xizang as the research object. According to the current situation of the mine slope， the rock mass structure of the slope and the development characteristics of the structural plane， the geological zoning of the current slope is carried out. The physical and mechanical parameters of the slope rock are obtained through the indoor physical and mechanical tests of the rock. The simplified Bishop and Morgenstern Price limit equilibrium methods are used to calculate the stability coefficients of each partition of the current slope under three load cases. After analysis， the safety factors of all load combinations on the current slopes of each geological zone meet the regulatory requirements， which can provide reference for the safety production of mines. |
