某铜钼矿深凹开采边坡稳定性数值分析

Slope stability numerical analysis of a copper molybdenum mine with deep concave

为了确定铜钼矿深凹开采边坡稳定性,通过金地矿业铜钼露天采坑边坡工程现场地质调查分析及室内岩石物理力学参数实验,确定了该矿采场边坡岩体的物理力学参数。采用极限平衡数值模拟分析方法对该矿边坡的稳定性进行了计算分析,确定了现状边坡的稳定状态,为矿山采场今后的部分决策提供了参考依据。

In order to determine the stability of the slope of the copper molybdenum mine,the engineering geological is investigated.Rock and physical and mechanical parameters of Jinmo mining open-pit slope are analyzed.The physical and mechanical parameters of rock mass in the slope of mining area are determined.The stability analysis of the mine slope is carried out by means of the limit equilibrium numerical simulation method.The stability condition of the slope is determined,which provides a reference for some decisions of the mine stope in the future.
