Surface Deformation Monitoring and Analysis of Pingchuan Mining Area Based on SBAS-InSAR Technology
摘要
Abstract
Taking Pingchuan mining area in Baiyin City as an example,we used SBAS-InSAR technology to solve the sentinel-1 data of the lift track in this area for two years,and obtained the quasi 3D surface deformation field in this area.Combined with nighttime light remote sensing data,we verified the reliability of surface deformation monitoring results,and used standard deviation ellipse method to analyze the spatio-tempo-ral evolution characteristics of regional deformation.The results show that①the average rate of maximum vertical annual settlement of quasi 3D surface deformation field in the study area is-16.75 cm·a-1,which is dominated by land subsidence.②The deformation centers of Pingchuan mining area are mainly distributed in the middle and northwest of Pingchuan District.③The increasing area of nighttime light value and the ac-celerating deformation area in the mining area have the characteristics of"following".④A total of 12 obvious deformation areas are identified in the area,all of which have the characteristics of settlement funnel.⑤From January 2020 to August 2020,the cumulative surface deformation intensifies in the northwest southeast direction.From August 2020 to April 2021,the cumulative surface deformation changes slowly in different directions.The spatial evolution of cumulative surface deformation shows that the main axis rotates counterclockwise.关键词
