摘要
传统的矿区地表变形监测获取数据量少、监测周期长、效率不高;结合LiDAR及RTK技术应用到煤矿区地表沉陷监测工作中,进行外业数据采集与内业数据处理,对得到的点云数据和生成的DEM进行煤矿区沉降变形分析,并以贵州某煤矿区为例进行了地表沉陷监测试验,满足精度要求,验证了该方法的可行性。
The traditional mine surface deformation monitoring has defects of low data amount, long monitoring period and low efficiency. This paper combined LiDAR and RTK technology applied to coal mining area surface subsidence monitoring, implemented data acquisition and internal data processing, analyzed coal mining area settlement deformation based on point cloud data and generated DEM, and tested the surface subsidence monitoring of a Guizhou coal mine, which met the requirements of precision and verified the feasibility of this method.
