摘　　要：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。According to the data of complex underground goaf investigation in Sandaozhuang open-pit mine of China Molybdenum Co.,Ltd,the Surpac three-dimensional model of the complex goaf was established,then,the 3D model was introdued into three dimensional finite element software MIDAS to establish a numerical model,finally,the numerical model was introdued into FLAC software to carry out calculation.According to the results of numerical calculation,considering the interplay between the analyzed goaf and neighboring goaf,the stability of hidden goaf within open-pit mining boundary was studied from the angle of stress and displacement.The study is of certain guided signification to the actual production in mining
