Abstract: The mining of Wantian Coal Mine and Xiejiagou Coal Mine is prone to trigger various geological disasters,posing a significant threat to the safety of life and property of residents in the mining area.To effectively monitor geological disasters caused by mine mining,SBAS-InSAR technology is adopted to calculate the Sentinel-1 data of 191 scenes from February 2017 to June 2023,and surface cumulative subsidence amount of the study area is obtained.The monitoring results show that there are three main concentrated areas of surface subsidence,with a maximum subsidence amount of-1 576.4 mm,distributed in subsidence area a,and the forming time of this subsidence area is relatively early.With the development of time,the three subsidence areas are gradually merged;The mining of adjacent mining areas can lead to instability of rock masses in unmined areas and the occurrence of surface subsidence;The occurrence of mountain collapse is closely related to mining in mining areas.The scope of collapse gradually increases with the mining scope expansion of mining areas,and the subsidence in the central area of collapse is relatively large,exhibits similar deformation trends on both sides.Propose measures to strengthen monitoring and early warning of geological disasters in mining areas,effectively ensuring mine safety production and geological environment protection,and providing scientific basis and technical support for prevention and control of geological disasters in mining areas.
