摘　　要：对于盘区开采的大规模地下矿山,从生产的角度出发,较小宽度的永久间柱和暂留矿柱、较大的矿房可以降低矿石的损失,提高矿山经济效益。本文参考该矿山开采采矿方法系统优化选择研究报告的基础上,根据矿山工程实际同时结合类似矿山的工程经验,从力学角度,利用FLAC3D软件对采场永久间柱宽度进行稳定性分析,在尽可能减小矿石损失同时,最大限度提高盘区开采的稳定性。For large-scale underground mines with panel mining,from the perspective of production,permanent pillars with small width and temporary pillars,and larger mining houses can reduce ore loss and improve mine economic benefits.This paper refers to the research report on the optimization and selection of the mining method of the mine.Based on the actual mine engineering and the engineering experience of similar mines,from the mechanical point of view,the stability of the permanent pillar width of the stope is analyzed using FLAC3D software.While reducing ore loss,it maximizes the stability of panel mining.
