摘　　要：汤丹铜矿受前期混乱开采影响,在地下存在大量不明采空区,具有分布不规律、形态复杂、安全风险大的特点.为全面掌握汤丹铜矿采空区形态、轮廓和体积,提高采空区调查测量精度与工作效率,采用三维激光扫描技术代替传统二维测量手段,对该矿地下采空区体积进行了扫描测量和统计计算.通过对扫描点云数据的处理,结合DIMINE软件,构建了采空区三维地质模型,可直观获取采空区边界、体积、内部形态及分布结构信息,并将扫描计算结果与矿山实测统计数据进行了对比,数据测量误差为0.9%~9.4%,验证了三维激光扫描系统在复杂采空区探测方面的适用性,为矿山安全生产提供了有效支撑.A large number goafs occurred in Tangdan Copper Mine,which characterized by irregularity distribution,complex shape and great security risk caused by the effects of previous garbled mining.In order to obtain the morphology,contour and volume of goaf of the mine,and improve the accuracy and efficiency of stope acceptance measurement,the underground volume of the mine is measured and calculated by adopting 3D laser scanning method instead of traditional measurement method.The three-dimensional geological model of goaf is established based on processing of scanning point-cloud data by using DIMINE software,which can obtain the information of boundary,volume,external morphology and distribution structure of goaf.In addition,the comparison study of scanning results and measured data of mine is done.The results show that the measurement is 0.9%~9.4%,which proved the three-dimensional technology is suitable for the complicated goaf detection.The above study results can provide effectively guarantee for the safety production of Tangdan Copper Mine.
