The serious collapsed range was determined from -455 to -464m level preliminarily, in which the maximum displacement of the shaft wall is more than 10m. The main collapse area is in the northwest of the main ore pass, and the maximum compressive stress is 41.750MPa. On this basis, the real three-dimensional data of collapse area was achieved by CMS detection and three-dimensional visual model of the deep main ore pass collapse area. It was determined that, the main collapsed ranges from -457 to -463m level, and the horizontal maximum collapse area is 92.92m², with main direction of collapse 28° north by west. The major axis is 14.5m, and the minor is 8.1m. The total collapse volume is 1035m³. Comprehensive analysis showed, the finite element analysis result is basically anastomosed with the measured result, and both of the methods verified and complemented mutually. The stress collapse damage of main ore pass is determined accurately and it establishes a firm foundation for formulating a reasonable restoration scheme of deep main ore pass., authors=LUO Zhouquan,

articleAbstract=针对某地下金属矿山深部主溜井垮塌破坏的工程实际,运用非线性有限元分析软件Midas/GTS,对该主溜井破坏情况进行数值分析;根据溜井及巷道位置关系建立有限元分析模型,进行计算并做二维剖切;根据其最大位移、等效塑性应变及应力特征,初步确定溜井主要垮塌标高范围为-455~-464m,主要垮塌区域为溜井西北部,井壁最大位移大于10m,围岩最大压应力达41.750MPa。在此基础上,采用空区三维激光探测系统(CMS),对垮塌主溜井进行三维激光探测;运用Surpac软件获取的探测数据,建立溜井垮塌区三维可视化模型,获取垮塌区三维空间信息;根据横剖面的垮塌面积和偏离中心线最大垮塌距离,精确确定溜井主要垮塌标高范围为-457~-463m,水平最大垮塌面积92.92m²,主要垮塌方向为北偏西28°,最大长轴14.5m,最小短轴8.1m,垮塌总体积1035m³。综合分析表明,有限元分析的溜井垮塌情况与实测结果基本一致,两者相互补充验证,可准确确定主溜井受力及垮塌破坏状况,为深部主溜井修复方案的合理制订奠定基础。,
