摘　　要：某铁矿为大型深凹露天矿,露天开采结束后将转入地下开采。为阻断露天坑与地下的水力通道,同时保持高陡边坡稳定,计划采用尾砂胶结固化回填露天坑。本文采用数值模拟的方法,对露天坑固化回填与地下开采的相互影响进行了模拟研究。结果表明,露天坑固化回填与地下开采之间基本上不存在相互影响。研究结果可为类似开采条件下的矿山提供参考。An iron mine is a large deep open pit.After the completion of open-pit mining,it will be transferred to underground mining.In order to block the hydraulic channel between the open pit and the underground,and maintain the stability of the high and steep slope,it is planned to backfill the open pit with cemented and solidified tailings.In this paper,the numerical simulation method is used to simulate the interaction between open pit solidification backfilling and underground mining.The results show that there is basically no interaction between open pit solidification backfilling and underground mining.The research results can provide reference for mines under similar mining conditions.
