Monitoring and Analysis of Subsidence in Mining Areas Combined with SBAS and IPTA Technologies
Huangling No.1 Coal Mine is a large-scale coal mine with a long history of mining. Large-scale mining has caused serious surface deformation. Based on Sentinel-1A data from August 2018 to April 2019,this paper applies SBAS and IPTA technologies to the mining subsidence monitoring of Huangling No.1 mining area to obtain surface subsidence information,and finally analyze the sur-face subsidence characteristics in detail from the profile lines,contour lines and feature points. The results show that the maximum an-nual average subsidence rate in the study area is-325 mm/a,and the maximum cumulative subsidence is-198 mm;with the passage of time and the advancement of the working face,the cumulative subsidence in time series continues to increase,and the range of sub-sidence is gradually expanded;this technology identifies the subsidence location and the subsidence influence range,which can pro-vide reference for local land subsidence control and prevention.
