High-intensity underground mining leads to huge surface deformation, and excessive deformation phase gradients could lead to interference unwrapping errors. Currently, the characteristics of surface subsidence cannot be obtained well by conventional DInSAR and its derivative technologies. In this paper, we propose a new method, which combines DInSAR and Offset-tracking technology to extract large-scale deformation accurately, and further restore settlement field shape using the GAUSS function model. We take Bu'ertai Mine, and Cuncaota No.1 and No.2 Mine in Shendong Mining Area as research areas and use the high-resolution RADARSAT-2 data with 5 m fine beam model (MF5) on February 13, 2012 and November 27, 2012 to obtain the mine subsidence boundaries at sub-centimeter level using DInSAR technology and the mine subsidence center at meter level using Offset-tracking method. The boundary subsidence value is -0.01~ -0.02 m and the central subsidence value is -1.0~ -4.0 m. The whole subsidence field is then retrieved by integrating above two results. Finally, the GAUSS function model is used to fit the mining subsidence boundary and central, and to reconstruct the characteristic curve of mining subsidence. Our results demonstrate that the Offset-tracking method could compensate the deficiency of DInSAR in large deformation extraction, and the combination of these two techniques could effectively and accurately extract large-scale subsidence field in mining areas.
