摘要
隔离矿柱是矿山地下开采浅部转深部开采的衔接部分,通过留设隔离矿柱,可为浅部空区处理与深部采矿方法变更提供条件。利用FLAC 3D软件对不同厚度人工隔离矿柱进行稳定性分析,确定了最佳人工隔离矿柱厚度。对类似矿山资源回收及安全生产具有一定的参考和借鉴意义。
Barrier pillar is the connecting part of the underground mining from shallow to deep.By reserving the barrier pillar,it can provide conditions for the shallow goaf treatment and the deep mining method change.In this paper,FLAC 3D software is used to analyze the stability of different thickness of artificial barrier pillars,and the optimal thickness of artificial barrier pillars is determined.It has certain reference and reference significance for similar mine resource recovery and safe production.
