摘　　要：根据矿山地下空区激光扫描方面的工程运用,结合Geomagic、3DMINE等软件,针对空区测量及后期点云数据处理中的各种问题,总结了空区扫描的操作处理方法,制定了针对复杂空区现场测量的方案,并且提出了一套比较简洁、高效的点云后期处理与三维建模流程;应用于福建源鑫矿业空区扫描的现场,较好地取得了现场复杂空区的测量数据,把大量点云数据进行简化优化,建立了空区巷道一体化的三维模型,探明了采空区位置、形态及分布情况,为后期空区剩余矿柱的回采及采空区的综合治理提供直观有效的支撑;研究结果对于类似空区处理有很好的借鉴作用.According to the 3D laser scanning engineering applications in the mined-out area underground space, combining with Geomagic software and 3DMINE software, the field operation and management method is analyzed and summarized aiming at the problems encountered in the measurement and the later space point cloud data processing. The scheme of measuring complex mined-out area is established with a set of relatively simple, efficient processing of cloud point and 3D modeling process; the measurement data is obtained effectively with the application in Fujian Yuan Xin mining cavity scanning; the model of the cavity and tunnel integration is established after the simplification and optimization of the point cloud data to verify the location, morphology and distribution which provides effective support for the comprehensive management of coal mined out area and later remaining pillar stopping. The research result provides a good reference for the similar cavity treatment.
