摘要
露天采场随着开采深度的增加,边坡高度逐渐增大,边坡稳定性问题日益突出,对矿山安全生产造成严重影响,开展矿山边坡稳定性分析是提前采取边坡灾害防控措施的关键。以某矿山采场边坡为研究背景,采用3DMine-Rhino相耦合建立采场三维模型,基于FLAC^(3D)数值模拟软件对采场西南帮边坡的应力、位移、塑性区展开分析研究,结果表明:在自重工况下边坡安全系数为2.37,边坡整体保持稳定,在自重+地震工况下边坡安全系数为1.11,边坡表面出现局部小范围破坏,边坡基本保持稳定状态。研究结论可为该矿山边坡稳定性评价提供理论参考。
With the increase of mining depth,the slope height of open-pit mines gradually increases,and the problem of slope stability becomes increasingly prominent,which seriously affects the safety production of mines.Conducting slope stability analysis of mines is the key to taking slope disaster prevention and control measures in advance.Taking the slope of a certain mining site as the research background,a three-dimensional model of the mining site was established using 3DMine-Rhino phase coupling.Based on FLAC^(3D) numerical simulation software,the stress,displacement,and plastic zone of the southwest slope of the mining site were analyzed and studied.The results showed that under the self weight condition,the safety factor of the slope was 2.37,and the overall stability of the slope was maintained.Under the self weight+earthquake condition,the safety factor of the slope was 1.11,and local small-scale damage occurred on the surface of the slope.The slope remained basically stable.The research conclusion can provide theoretical reference for the stability evaluation of the mine slope.
