摘　　要：针对某金属矿深部4#主溜井筒壁中段卸矿不断冲击受损垮塌的现状,运用空区激光探测系统(CMS)对4#主溜井进行跟踪探测,获取垮塌区相关的实测信息,建立精确的垮塌区三维可视化模型,准确获取溜井垮塌区三维形态、空间位置和实际边界。通过对溜井垮塌前后三维模型间的布尔运算,得出了垮塌区体积的大小、最大垮塌区横剖面面积等,实现了溜井垮塌严重程度的三维可视化分析。通过对-600 m水平溜井垮塌范围与周边巷道位置关系分析,确定了溜井对周边巷道的影响程度,为4#主溜井的恢复加固及周边巷道的安全分析提供了可靠的技术支撑。The condition of collapse in the 4# main ore-pass of metal mine which caused by the on-going ore discharging in the middle is serious. Relative measured information of the collapse can be acquired by CMS detecting and tracking the main ore-pass. On the basis of the information,accurate 3D visualization model of the collapse can be established,and three-dimensional configuration,spatial position and actual boundary of collapse area of ore-pass be obtained. Through Boolean calculation between the 3D models which established before and after the collapse,volume size and the maximum transverse section area of collapse zone were obtained. Thus,the 3D visualized analysis of the condition of the collapse of ore-pass was implemented.Finally,the degree to which ore-pass affects the peripheral roadway are confirmed,via analysis of the position relations between collapse range of ore-pass in- 600 m level and surrounding roadway. The analysis provides reliable technical support for the restoration and reinforcement of 4 # main ore-pass and the safety of surrounding roadway.
