In this paper, the author use the DORIS software to conduct the differential interferometric processing of existing data and extracts ground deformation fields in different periods of Yaoqiao mining area, Xuzhou. After that, the analysis is carried out by combining with characteristics of ground exploitation subsidence, and the comparative analysis of land subsidence data obtained by conventional methods is conducted. The results show that: the land subsidence of Yaoqiao mining area is quite consistent to the exploitation subsidence rules; in addition, D-InSAR can monitor minor changes of exploitation subsidence boundaries in mining areas and the evolution trend of subsidence surface, and also can measure the subsidence speed. It has proved that the InSAR technology can conduct continuously effective dynamic monitoring of ground deformation in mining areas from this example. In terms of the regional continuous ground depression, DInSAR is much better than the traditional methods of measurement. The development of this new Earth observation technology has important practical significance in promoting the improvement of China's "digital mine" system and guiding the planning and preservation of buildings and road systems in mining areas.
