摘　　要：露天转地下开采的矿山 ,其境界顶柱稳定性将直接影响到矿山的安全生产。本文以石人沟铁矿为例 ,运用ANSYS有限元分析软件 ,建立三维数值模型 ,模拟了动载荷作用下分步回采引起顶柱及采场的应力、变形情况 ,并对结果进行了详细的分析 ,得出了有价值的结论 。For a mine to be changed from an open pit to underground stope, the stability of the boundary pillar has direct influences on the safety production of the mine. Taking Shirengou Iron Mine as an example, a three-dimensional numerical model is built with a finite element analytical software to simulate the stress and distortion of the pillar and stope caused by fractional stoping under dynamic load. The results were analyzed in detail, which reaches a conclusion useful for guiding safety production of the mine.
