露天转地下开采矿山高边坡位移场分布规律

Distribution regularity of upper slope displacement field in the case open pit mine is transformed into underground mine

利用ANSYS有限元大型数值模拟分析软件,通过建立石人沟铁矿露天转地下开采后矿山高边坡三维数值模型,进行数值模拟计算,分析露天转地下开采后矿山高边坡的稳定性。结果表明,地下开采对石人沟铁矿露天边坡整体稳定性影响不大,矿山高边坡整体是稳定的。

The ANSYS finite element simulation software is used to establish an upper slope data 3-D model of Shirengou Iron Ore Mine that is transformed from open pit mining into underground mining. By means of this model, the simulation calculation is carried out for analyzing the stability of upper slope. The result of calculation indicates there is no great influence of underground mining on stability of upper slope that is stable.
