摘　　要：为了预防某铁矿开采造成地表塌陷引起采空区冒落冲击气浪危害,采用数值模拟的方法对地下错综复杂的采空区群围岩稳定性展开分析,根据模拟结果,将该矿采空区稳定性划分为稳定、亚稳定及基本稳定3种状态,提出两个中段保留部分垂直矿柱与中段水平保安矿柱方,法预防顶板冒落冲击气浪,为企业安全生产提供理论及技术支持。In order to prevent the hazards of goaf collapse caused by surface subsidence during the mining of a certain iron mine,numerical simulation methods are used to analyze the stability of the surrounding rock of the complex underground goaf group.Based on the simulation results,the stability of the goaf in the mine is divided into three states:stable,sub stable,and basically stable stages.Two methods of retaining some vertical pillars in the middle section and horizontal safety pillars in the middle section are proposed to prevent collapse impact waves,providing theoretical and technical support for enterprise safety production.
