摘　　要：溜井是矿石运输的主要通道,溜井内部的精细测量是评估井筒健康的重要步骤。为精细测量李官集铁矿0 m中段8#采场溜井内壁的破损情况,通过翼目神HM100型三维激光扫描仪对其进行扫描测量,进行点云数据采集处理、模型建立、成果分析和溜井健康状况评估;进一步通过Rhino-FLAC3D耦合建模分析方法,开展溜井在自重应力及地应力作用下的稳定性分析;最后基于分析结果提出了符合实际的溜井放矿管理和修复措施。结果表明:溜井在自重应力及地应力作用下相对稳定,溜井井壁破损的主要原因为矿石放矿过程中的冲击及磨损作用,为李官集铁矿溜井的安全运行提供基础依据。The chute is the main channel for transporting ore,and fine survey of the interior of the chute is an important step in evaluating its health.In order to assess the damage to the interior wall of the chute in the 8#mining area of the 0m section of Liguanji Iron Mine,a Yimushen HM1003D laser scanner was used to scan and measure the chute.Point cloud data collection and processing,model building,result analysis,and evaluation of the health of the chute were carried out.Furthermore,the stability analysis of the chute under self-weight stress and ground stress was conducted through the Rhino-Flac3D coupling model⁃ing and analysis method.Finally,based on the analysis results,practical management and repair measures for the chute were proposed.The results showed that the chute was relatively stable under self-weight stress and ground stress,and the main cause of damage to the chute wall was the wear and tear caused by the im⁃pact of ore discharge during the mining process,which can provide a basis for the safe operation of the chute in Liguanji Iron Mine.
