京西山区关闭矿井残余地表形变的InSAR监测与规律分析
InSAR Monitoring and Law Analysis of Residual Surface Deformation of Closed Mines in Mountainous Area of the West of Beijing
摘要
Abstract
The residual surface deformation of old goaf area in mountainous area of the west of Beijing will affect the safety of above facilities,and induce mountainous collapse and slip disasters.Due to the short time and low spatial resolution of on-site observation data,there is insufficient understanding of the spatial distribution and long-term evolution laws of residual surface deformation in goaf area.Taking the closed mine of Datai in mountain area of the west of Beijing as the object,we used SBAS-InSAR technology to process the ascending and descending orbit data of Sentinel-1 from 2014 to 2023,and constructed a two-dimensional deformation monitoring and fusion analysis method for mining area.The results showed that the vertical maximum settlement speed reached-54.49 mm/a,and the settlement speed decreased by 53%after closing the pit.The horizontal direction showed the dominant feature of eastward movement,with a maximum speed of 21.3 mm/a.The correlation coefficient between InSAR and level data reached 0.96,and the root mean square error was 2.08 mm.The research reveals the spatio-temporal evolution law of residual surface deformation in closed mine,and the proposed monitoring method can provide technical reference for similar mines.关键词
