摘　　要：引进精度高且使用方便的三维激光扫描技术,对矿井掘进过程中的围岩变形进行监测。将三维激光扫描获取的点云数据转化为三维模型及AutoCAD平面图形,以此对比巷道断面的变化情况。对罗河铁矿-620 m矿段卸矿站掘进过程进行三维激光扫描,监测并分析围岩在掘进过程中的变形情况。分析结果表明,三维激光扫描技术能够有效地监测围岩状态与变形,具有非接触测量、高数据采样率、高分辨率和高精度的优势,为矿山安全生产提供了有力的技术支持。The three-dimensional laser scanning technology with high precision and convenient use is introduced to monitor the deformation of surrounding rock in the process of mine excavation.The point cloud data obtained by three-dimensional laser scanning is transformed into three-dimensional model and Auto⁃CAD plane graphics to compare the changes of roadway section.Three-dimensional laser scanning is carried out on the excavation process of the unloading station in the-620 m section of Luohe Iron Mine to monitor and analyze the deformation of surrounding rock during excavation.The analysis results show that the threedimensional laser scanning technology can effectively monitor the state and deformation of surrounding rock,and has the advantages of non-contact measurement,high data sampling rate,high resolution and high precision,which provides strong technical support for mine safety production.
