Abstract: In recent years, the government has attached great importance to the monitoring and management of ground subsidence, but little research has been done on the phenomenon and mechanism of ground uplift. In this paper, PS-InSAR and NSBAS are used to monitor the ground deformation in Zibo with Sentinel-1 ascending and descending orbit data. It analyzes the consistency of lifting in the area with coal mining conditions through the date.

Key words: PS-InSAR, NSBAS, ground uplift, time series, Sentinel-1
