基于SIGMA/W的露天矿软弱基底排土场安全距离研究

Research on Safe Distance of Soft Basement Dump in Open Pit Mine Based on SIGMA/W

摘要: 以内蒙古某露天煤矿软弱基底排土场为研究对象,应用GeoStudio有限元分析模块SIGMA/W,揭示出顺倾和逆倾不同基底形态、边坡角及排弃高度条件下周边地表面的变形规律,并最终确定了合理的排土场安全距离。

Abstract: Taking soft basement dump of open pit mine in Inner Mongolia as a study case, we apply finite element analysis module SIGMA/W of GeoStudio to reveal deformation laws of surrounding ground surface under conditions of inclined basement and inverse inclined basement, different slope angle and slope height, and ultimately determine the reasonable safe distance.
