Abstract: Differential interferometry synthetic aperture radar (DInSAR) is a new measuring technique developed in resent years to monitor the deformation of ground surface, which has been applied successfully in many applications including mining areas. In this paper, 7 ascending Sentinel-1A images from November 26, 2016 to February 6, 2017 are used to monitor the deformation of mining areas in Yangquan Mining Area using DInSAR technique. To effectively monitor surface deformation of the mining areas, the orbit error and topographically-related atmosphere delay that were not well dealt with in the DInSAR technique have been corrected by combining a bi-quadratic model and a linear model. The experimental results show that the overall of the study area is the subsidence tendency and the distribution of funnel-shaped subsidence is consistent with the location of the mining areas. Within a period of 72 days, the maximum cumulative settlement of the two areas in Xinjing Mining Area is -18.82 cm and -22.33 cm respectively.
