摘　　要：崩落法开采会引起地表塌陷,在国家对于矿山安全和环保监管日益严格的背景下,应用充填法开采的矿山越来越多,许多矿山已开始由崩落法向充填法转型。为保证开采安全,在崩落法和充填法开采范围间需设置隔离矿柱,确保二者互不干扰。隔离矿柱的稳定性受影响因素较多,通过数值模拟手段,基于点安全度法,对隔离矿柱的安全性进行了分析,提出了隔离矿柱尺寸。研究结果可为类似矿山矿柱留设方式提供一定的参考。Caving mining method can cause ground surface subsidence.Against the backdrop of increasingly strict national regulations on mine safety and environment protection,more and more mines are using filling mining method,and many mines have begun to transition from caving method to filling method.To ensure mining safety,barrier pillars need to be set up between the mining ranges of caving method and filling method to ensure that the two mining methods do not interfere with each other.The stability of isolation pillars is influenced by many factors.Through numerical simulation,based on the point safety degree method,the safety of barrier pillars is analyzed,and the size of barrier pillars is proposed.The research results can provide certain reference for pillar arrangement in similar mines.
