Application of Interferometric Synthetic Aperture Radar Technology in monitoring coal mining subsidence area of Liaoyuan

The development of mineral resources in the northern mining area of Liaoyuan City, Jilin Province has made a great contribution to China’s national economic construction, but the mining leads to the destruction of the mine geological environment is also very serious, especially in the goaf. In order to promote the sustainable development of cities with exhausted mineral resources and strengthen the comprehensive treatment of the mine geological environment, the premise of the treatment is to monitor the main deformation areas and deformation laws. In view of the above problems, this paper uses InSAR Technology for ground deformation monitoring to obtain the ground deformation rate in the area from October 2016 to October 2021. At the same time, UAV aerial survey and ground investigation are carried out. The results show that the deformation signs in the collapse area in the area are consistent with the interpretation results of InSAR technology, indicating that InSAR technology has a good application in deformation monitoring in coal mining subsidence area, and has broad prospects.
