| 摘 要： | 针对矿山露天转地下开采后尾矿库容积不足。新建尾矿困难的现实问题,提出利用废弃的露天坑排放尾矿的技术方案,并采用ANSYS三维有限元数值模拟方法,对排尾后的地下采场稳定性从排尾高度、应力场等方面进行了模拟研究,分析了露天坑排尾后地下采场的稳定性,并针对可能出现的问题提出了具体的工程控制措施。

| Abstract: | According to the existing condition of Chengijagou Iron Mine from the open-pit to underground and the fact that the cubage of the taring base is not adequate enough and the confiscation of land for the new tailing-dam is very diffcult,a technical scheme to make good use of dumped open pit for discharging ore tailing is presented in this paper.The ANSYS 3D-finite-element numerical simulation method is adopted and the stability mechanism of the un- derground stope after dischargingtailing in the openpit is an... |
