Application of SBAS-InSAR Technology in Land Subsidence Monitoring
Compared with the traditional land subsidence monitoring methods,the small baseline set SBAS-InSAR technology has significant advantages in carrying out large-scale and long-term land subsidence monitoring.Therefor,SBAS-InSAR technology was used to process 26 Sentinel-1A images covering a mining area in Jining,ob-taining the annual average subsidence rate and cumulative subsidence amount of the mining area from January 10,2019 to November 19,2021.The research results indicate that there are different degrees of settlement changes caused by underground coal mining in the study area,with the maximum cumulative settlement reaching 249 mm and the maximum settlement rate reaching 86 mm/a.The cumulative subsidence maps monitored at different imaging times visually and dynamically reveal the ground subsidence process caused by continuous underground coal mining.
