基于三道庄露天矿地下复杂采空区的调查资料,建立了复杂采空区的Surpac三维模型,将模型导入MIDAS三维有限元软件建立数值计算模型,最终导入FLAC软件进行计算。根据数值计算结果,从应力和位移的角度,同时考虑被分析空区与邻近空区之间的相互影响作用,分析研究了开采境界下空区的稳定性状态,对矿山实际生产具有一定指导意义。
Based on the survey data of underground complex goaf in Sandouzhuang open-pit mine, the three-dimensional model of Surpac in complicated mined-out area was established. The model was imported into MIDAS three-dimensional finite element software to establish the numerical calculation model and finally to FLAC software for calculation. According to the numerical results, from the perspective of stress and displacement, taking into account the interaction between the analyzed empty area and the adjacent empty area, the stability status of the open area under the mining condition is analyzed and studied, which is of guiding significance to the actual production of the mine .
