Large-scale, rapid detection method of surface subsidence in western mining area

In view of the character of mining disaster and the limitation of traditional methods of earth surface deformation monitoring in western mining area, an attempt at adopting InSAR techniques in dynamic deformation monitoring in west mining area has been developed. This paper takes Shaanxi Province Binchang mining area as study area, processes the SAR image by differential interference, obtains the deformation image of Binchang Coal Mining Area, This shows that the InSAR can rapid detect the surface subsidence areas in a large area (100 km×100 km). InSAR technology will be widely used in mining damage dynamic monitoring in western mining area.
