摘　　要：常规采空区物理探测方法受空区形态及地质情况影响而降低精确度,不能准确地输出空区三维形态信息,且后期分析困难。激光探测技术能很好地解决这一问题,但是针对遗留大量繁杂凌乱点柱的空区群,无论前期探测,还是后期建模难度都变大。以江西某钨矿空区群为背景,利用三维激光扫描系统FARO进行了精密探测,采用Geomagic-studio软件对探测产生的点云数据进行了整理,并进一步地探索了基于Minesight软件和3Dmine软件构建的三维空间模型与FLAC3D数值模型耦合问题。实践证明,应用FARO系统建立的三维空间模型,能较方便地对采空区的残矿量、采空区规模进行精确统计;在此基础上,基于实测三维空间模型构建的FLAC3D数值模型,可对空区群的稳定性进行分析。Due to the influence of the goaf pattern and geological condition,the conventional physical survey for minedout area lowered the accuracy.It can not accurately output the three-dimensional space information and make post analysis difficult.Laser detection technology solved this problem well.But for the goaf group with a lot of complicated and messy point pillars,a bigger difficulty exists in both pre-detection and post-modeling.With the goaf group in Jiangxi Tungsten Mine as background,the three-dimensional laser scanning system FARO was adopted to make precise detection,and the point cloud data generated from the survey were disposed with Geomagic-studio software.Then,the coupling of three-dimensional space model and FLAC3D numerical model based on Minesight software and 3Dmine software was further explored.The practice has proved that the three-dimensional spatial model based on FARO system can more accurately statistic the amount of residual ores in mined-out area and its size.On this basis,FLAC3D numerical model based on three-dimensional measured space model can be used to analyze the stability of the goaf group.
