摘要
基于对华鑫铁矿采空区群的三维激光精密探测,采用FLAC3D软件分析计算矿体开采后采空区群内留存矿柱的稳定性状况,辨识了采空区群的安全隐患。最后,提出采用强制放顶崩落法处理典型巨大规模复杂采空区群,并回收空区群内的隐患资源,从而稳定企业的生产经营状态。
Based on 3D laser precision detection of goaf group in Huaxin Iron Mine,the stability of residual pillar in the goafs was analyzed with FLAC^3D software,and potential safety hazards of complex goafs were identified.Finally,forced caving mining method was adopted to dispose the large and complex goaf group and recover the hidden trouble resource in these goafs,so as to ensure production and operation in this mine.
