  • In view of defects of long monitoring period, high cost and incomprehensive monitoring existed in monitoring technology of surface subsidence in mining areas by use of geodesic leveling and GPS measurements, a monitoring method of surface subsidence based on D-InSAR technology was proposed. Taking Huainan Coal Mining Area as experimental district, two-pass D-InSAR technology was used to get surface deformation image of Huainan Coal Mining Area in experimental time by use of experimental data of two scenes ALOS PALSAR data. The information of surface subsidence of coal mines of Huainan Coal Mining Area was analyzed. The result showed that the subsidence of mining area is 5~25 cm and corresponds to practice. Therefore, the monitoring method based on D-InSAR technology is an effective method to obtain information of surface subsidence for mining area.
