摘要: 针对程家沟铁矿利用废弃的露天坑排放尾矿这一现状,从分析矿山工程地质、水文地质、矿岩物理力学参数入手,并结合矿山的实际情况,采用ANSYS三维有限元数值模拟方法,对排尾后的地下采场稳定性进行了模拟研究,从而确定了排尾高度和排尾后的地下采场参数,并针对可能出现的问题提出了具体的工程控制措施。

Abstract: In view of the fact that Chengjiagou Iron Mine utilizes its discarded open pit for tailings deposit, simulation study is made on the stability of underground stope when the open pit is used for tailings deposit by ANSYS 3D finite element numerical simulation method based on the analysis of the mine engineering geological, hydrogeological and ore-rock physical mechanic parameters and in light of the mine reality. As a result, the appropriate tailing heap height and underground stope structural parameters are determined and specific engineering control measures are proposed for potential problems.
