| 摘要 | In order to solve the problems of small monitoring range, long time and high cost of existing sedimentation observation methods, based on two-view sentinel No. 1 radar images of Guqiao mining area in Huainan City from November 4, 2017 to November 28, 2017, surface change information was obtained in combination with D-InSAR, and the three-dimensional surface deformation was monitored by two-pass method and single line of sight D-InSAR method. The results show that during the research period of 24 d, the maximum deformation of the mining area reached 71 mm, and the southern subsidence was the most obvious, which was in line with the mining subsidence law. The maximum displacement from the north to the south was about 250 mm, while the maximum displacement from the east to the west was about 80 mm, and the maximum subsidence in the center was 110 mm. It is concluded that D-InSAR technique has a good effect on the inversion of the mining subsidence, and this method is suitable for three-dimensional surface monitoring in areas with similar geological conditions. The monitoring results have certain reference value. |
