摘　　要：采空区的存在对露天矿生产形成了重要安全隐患,准确取得采空区详细信息对露天矿安全生产具有重要意义。三维激光扫描系统能准确对煤矿采空区信息进行定位、分析与建模,利用该系统在平朔东露天矿采空区进行激光扫描,运用Micromine软件进行三维建模,确定采空区空间位置、形状及大小,并结合3D mine软件建立露天矿矿模与现场穿孔爆破工作,为采空区的处理提供了科学、准确的技术支持。The existence of goafs formed a serious hidden safety trouble to open-pit mine production,so it was significant to obtain accurate information of goaf.The Cavity-Autoscanning Laser System（C-ALS）,with accurate functions of locating,analyzing and modeling,was applied to scan goafs in Pingshuo east open-pit coal mine.Then a three-dimensional model was established with Micromine software,so as to determine the position,shape and volume of the goaf.Furthermore,combined with the establishment of an open-pit mine model with 3D mine software as well as field drilling and blasting,the scanning result could provide technical and accurate support for goaf treatment.
