| Abstract: | D-InSAR (Differential interferometry synthetic aperture radar) technology has unique advantages and great development potential in monitoring the subsidence of mining areas. In order to analyze and obtain the changes of the ground subsidence in the Jining mining, ALOS PALSAR data in L-band with high vegetation penetration capacity are selected to conduct dynamic monitoring of coal mining collapse based on two-track D-InSAR technology to obtain the subsidence information. Moreover, the monitoring results are compared with the leveling data. Furthermore, it provides theoretical basis and technical support for effectively protecting and restoring the mine geological environment. |
