Inordertostudythedevelopmentlawofsurfacedeformationofawell-water-solu-ble mine， the Sentinel-1A imagedata of the ESA from November 12， 2016 to June 06， 2019was selected， and the high-coherence and surface time series deformation maps of the study area were obtained by SBAS-InSAR technology.According to the number of high-coherence points and their parameters， the settlement area and settlement volume of the study area are inverted， and the high coherence point of the study area is interpolated by Kriging interpol a-tion method to obtain the data of the settlement funnel， and then compared with the level-ing data.The experimental results show that the maximum cumulative settlement of the surface of the study area from November 2016 to June2019 is 246mm，The maximum set-tlement area is 1.26km² and the maximum settlement volume is 118 336m³ where the set-tlement value of the high coherence point is greater than 10mm.The root mean square er-r or between the calculating result and the leveling data is士8mm.The development of sur-face settlement funnel and the internal bearing water pressure of the cavity have the same influence on the stability of the ground surface.The in version results of the settlement range and volume provide the basis for land protection and reclamation of the study area in the future.
