基于Slide程序对云南某矿排土场边坡稳定性与不确定性分析

Slope stability and uncertainty analysis of a mine dump from Yunnan based on Slide program

露天矿排土场边坡的稳定性对露天矿山安全有序的生产与运行起着至关重要的作用。该文采用极限平衡法对排土场边坡进行了稳定性分析,通过排土场边坡的各种不确定影响因素及其相互关系,对排土场边坡进行了不确定性分析。基于Slide程序对云南某露天矿排土场进行了简要分析与模拟,其模拟结果与该排土场现状基本吻合,同时分析了该排土场的不确定性,为今后如何进行堆排提出了建议。

Slope stability of the dump in open-pit mines is essential for the safe and orderly surface mine production and operation. The paper analyzed the slope stability of the dump with limit equilibrium method,considered every uncertain adverse influence factor of the dump and their interactions,and according to them carried out uncertainty analysis. Simple analysis and simulation of a dump in one open-pit mine from Yunnan based on Slide program showed a consistent result with the status of the dump,and an uncertainty analysis was conducted. Suggestions have been given for dumping in the future.
