井工开采对边坡稳定性影响的有限元分析

边坡下方井工开采是一个露天煤矿普遍存在的问题。本文采用有限元方法针对某一具体实例进行了数值模拟。模拟考虑了岩体力学特性及岩体结构特征,并模拟了井采过程。通过井采前后边坡岩体应力分析、位移分析,对边坡下方井工开采对边坡稳定性影响获得了一些认识。

A Finite Element Analysis of the Influence of Underground Mining on the Slope Stability of Open-pit Mine

In open-pit mines, the problem of underground mining under the slope is usually encountered. By means of the finite element method, a numerical simulation of an actual instance is made in this paper. In the simulation of the process of underground mining, mechanical properties and structural features of rock mass are considered. Some new ideas concerning the influence of mining under the slope on the slope stability have been gained based on the stress and displacement analysis of slope rock mass before and after underground mining.
