新桥矿露采下盘最终边坡稳定性分析

Stability analysis of footwall ultimate pit slope in Xinqiao Pyrite Mine

基于对新桥矿露采下盘边坡的地质概况和岩石物理力学性质分析 ,采用极限平衡理论 ,通过双滑面型破坏模式的计算 ,对边坡作了稳定性分析。

Based on geological condition and mechanics properties of open pit footwall slope rock in Xinqiao Pyrite Mine,the stope's stability is analysed by calculation of double slide face type failure mode with limit equilibrium theory.
