摘要：The ground surface deformation caused by mining damages the ecological environment and severely hinder economic development in the mining area. The acquisition of three-dimensional ground surface deformation in a mining area helps to improve understanding of the process and mechanism of ground surface deformation caused by mining and helps to prevent and control this type of disaster. In this paper, eleven TerraSAR-X images and five Radarsat-2 images covering the 52304 working face in the Daliuta mining area were used to obtain the time-series line-of-sight (LOS) direction deformation and azimuth direction deformation based on different SAR platforms by application of the small baseline subset (SBAS) pixel offset tracking method. According to the three-dimensional solution principle of multiplatform SAR images and 72 GPS points, the accuracy of deformation in the east-west direction is 0.22 m, while the accuracy in the north-south direction is 0.21 m, with an accuracy of subsidence of 0.34 m.
