露天高陡边坡稳定性分析

Stability Analysis of Open-pit High and Steep Slope

为了研究露天矿岩质高陡边坡的稳定性,文章以某露天矿为实例,在对前期资料整理和数值模拟的基础上,评价矿山在露天开采产生的岩质高陡边坡稳定性情况。分析结果认为:现状露天矿山开采产生的高陡边坡整体稳定,不存在大的隐患,可以进行后续开采作业,但是鉴于边坡上部岩体风化严重,在多排孔爆破作业时,应实时监测。

An open-pit mine was taken as an example,and the stability of high and steep rock slope produced by open-pit mining was evaluated on the basis of previous data collation and numerical simulation in order to study the stability of high and steep rock slope in the open-pit mine.The analysis results show that the high and steep slope produced by the current open-pit mining is stable,and there is no big hidden danger,so the subsequent mining operation can be carried out.However,in view of the serious weathering of the upper part of the slope,it shall be monitored in real time when the multi-row hole blasting operation is performed.
