摘　　要：随着地面三维激光扫描技术(3D TLS)的发展,对矿山边坡进行高精度、非接触式的变形监测成为可能。本研究围绕某金属矿区工作面采空区上方的边坡展开,通过详细的地面点云数据采集、特征提取、匹配分析,以及变形分析,展示了3D TLS在矿山边坡监测中的应用。研究成果不仅揭示了边坡在不同时间尺度上的变形特征,而且提供了一个准确评估边坡稳定性和预测潜在滑坡风险的方法论基础。With the development of ground three-dimensional laser scanning technology(3D TLS),it is possible to conduct high-precision and non-contact deformation monitoring of mine slope.This study focuses on the slope above the goaf of a metal mining face,,and demonstrated the application of 3 DTLS in mine slope monitoring through detailed ground point cloud data collection,feature extraction,matching analysis and deformation analysis.The results not only reveal the deformation characteristics of slopes at different time scales,but also provide a methodological basis for accurately assessing slope stability and predicting potential landslide risk.
