摘　　要：尾矿库是矿山生产的重要组成部分,直接关系到周边环境和居民的安全,因此对坝体变形进行准确、高效的监测尤为重要。为解决现有尾矿库变形监测存在的费时、费力、效率低等问题,实现对尾矿库高效率、高精度的变形监测,以南美洲某尾矿库坝体为研究对象,使用三维激光扫描仪和高精度全站仪获取了13期数据,分析了三维激光扫描技术在尾矿库监测中的应用效果,并与高精度全站仪监测数据比较。结果表明,三维激光扫描技术能够快速获取高精度三维数据,并实现对坝体表面的全覆盖扫描,可更准确地分析和评估坝体的变形情况。三维激光扫描技术为尾矿库坝体变形监测提供了一定的参考和实践意义。Tailings reservoir is an important part of mine production,which is directly related to the safety of surrounding environment and residents,so it is particularly important to monitor the deformation of dam body accurately and efficiently.In order to solve the problems of time-consuming,labor-intensive and low efficiency existing in the deformation monitoring of tailings reservoir,and realize the deformation moni-toring of tailings reservoir with high efficiency and high precision,13 periods of data were obtained by using 3D laser scanner and high-precision total station for the dam body of a tailings reservoir in South America,and the application effect of 3D laser scanning technology in the monitoring of tailings reservoir was ana-lyzed.And compared with the monitoring data of high precision total station.The results show that the 3D la-ser scanning technology can quickly obtain the 3D data of high precision,and realize the full coverage scan-ning of the dam surface,which can analyze and evaluate the deformation of the dam more accurately.3D la-ser scanning technology provides a certain reference and practical significance for monitoring the deformation of tailings reservoir dam.
