摘　　要：结合采矿方法创建了回采过程数值计算模型,采用有限元分析软件对不同开采顺序下的采场顶底板应力、位移等情况进行了模拟计算,同时对不同开采方案引起的地表位移情况进行了分析,最终确定了最优的回采顺序及开采方案。研究结果可为矿山的安全、高效生产提供技术指导和决策依据。A numerical calculation model was established for stoping based on the mining method. Simulation calculations were conducted using finite element analysis software for the stress of stope＇s roof and floor, as well as the displacement situation based on different mining sequences. Meanwhile, surface displacement caused by different mining methods was analyzed. An optimal stoping sequence and a mining program were finalized. It can provide some technical guidance for the safety and efficient production on mine.
