Study on impact of tectonic structure surface on stability of end-slope mining process in open-pit mine

  • 摘要: 基于某巨厚煤层露天矿端帮边坡内部赋存构造结构面问题,采用极限平衡法并结合数值模拟分析不同大小、位置的结构面在端帮开采时对边坡稳定性的影响。结果表明:结构面的存在会使端帮边坡稳定性低,且结构面越长、距离端帮坡底越近,对边坡稳定性影响越大;结构面不会影响边坡稳定性系数变化的趋势,也不会影响最大剪应变增量的转移情况。
    Abstract: Based on the problem of tectonic structural surfaces existing in the end slope of huge thick coal seam open-pit mine, this paper uses the limit equilibrium method and numerical simulation to analyze the influence of tectonic structural surfaces of different sizes and positions on the slope stability during end slope mining. The results show that the existence of tectonic structural surfaces will reduce the stability of end slope, and the longer the structural plane and the closer it is to the bottom of end slope, the greater the impact on slope stability; the structural surface does not affect either the trend of slope stability coefficient variation or the transfer of maximum shear strain increment.
