文章以大柳塔52304工作面为实验区，利用X波段、高分辨率、短重访周期的TerraSAR-X影像数据，进行时间序列的合成孔径雷达差分干涉测量（DInSAR）处理，获取了工作面采动过程中下沉盆地的形变信息。利用ENVI提取下沉值大于等于10 mm的下沉盆地，并用伪彩色显示，叠加工作面图，结合工作面回采的进度表，提取了不同阶段下沉盆地的超前影响角、边界角等参数，对比实地观测参数。实验结果表明，可以利用高分辨率影像的DInSAR技术监测下沉盆地边缘及提取边界角。

Taking 52304 working face of Daliuta Town as the experimental area ,an experiment of time-series differential interferometry synthetic aperture radar (DInSAR) was performed by adopting Terra-SAR-X image data that had high resolution and short revisit cycle .The deformation information of the subsidence basin in the mining process was obtained .The subsidence basins whose subsidence values were larger or equal to 10 mm were extracted by using ENVI software and displayed with pseudo col-or ,and combining with the mining face recovery schedules ,the parameters such as advanced influence angle and the boundary angle of subsidence basin at different stages were extracted and compared with those of field observation .The result suggests that DInSAR technique with high resolution image is feasible in monitoring the subsidence basin edge and extracting the boundary angle .
