| 摘 要： | 主要针对某露天矿进行露天地下联合开采而可能带来的矿房矿柱的稳定性问题进行模拟分析。项目开展过程中对该矿山进行了现场地应力测试和岩体力学测试分析，并对可能发生的工况建立9种计算模型，建立有限元2D及3D计算模型进行数值模拟，为该矿山后续设计提供基础依据，也为其他类似矿山提供借鉴意义。

| Abstract: | Mainly aimed at simulation and analysis of the stability of the rooms and pillars of an Open-pit mine in the process of open-pit underground combined mining.Data of in-situ measurement of ground stress and rock mechanics was analyzed in the process of project of the mine.And 2D and 3D finite element model were set up for possible conditions in the nine calculation models.The calculation results of the finite element would provide the basis foundation to the subsequent design of the mine and greater reference significance to other similar mines. |
