Mine subsidence monitoring based on SBAS-InSAR technology
In order to solve the problems of low efficiency,low precision and low spatial coverage of traditional monitoring technology means in surface subsidence monitoring of open-pit mining area,the article presents the monitoring method based on Sentinel-1A data and SBAS-InSAR technology.The article uses SBAS-InSAR technology to process 20 views of Sentinel-1A image data to monitor the surface subsidence trend of Zoomlion Rensselaer open-pit mine area from August 2023 to April 2024.The analysis results show that there is a significant surface subsidence phenomenon in the study area,and the subsidence area is mainly concentrated in the soil discharge field,and the most serious subsidence is found in the soil discharge field in Area A,in which the maximum subsidence rate reaches-139 mm,while the subsidence in the soil discharge field in Area B is smaller.The subsidence trends of the two survey lines in Area A and Area B are all in the form of V-shaped and funnel-shaped.The settlement value varies linearly with time in Area A and Area B dump.
