基于SBAS-InSAR技术的广东省典型尾矿库地表形变监测与分析
Surface Deformation Monitoring and Analysis of Typical Tailings Ponds in Guangdong Province Based on SBAS-InSAR Technology
摘要
Abstract
[Objective]Aiming at the limited coverage of traditional monitoring methods for tailings ponds in South China's densely vegetated and topographically complex regions,this study takes 10 typical tailings ponds in Guangdong Province as research objects to evaluate the applicability and practical value of SBAS-InSAR technology for long-term deformation monitoring of tailings ponds at a regional scale.[Methods]Ba-sed on Sentinel-1 ascending orbit SAR images acquired from October 2020 to October 2023,the Small Baseline Subset Interferometric Synthetic Aperture Radar(SBAS-InSAR)technique was employed to retrieve the time-series surface deformation characteristics of tailings ponds in the study area.[Results]The inversion results indicate that,during the monitoring period,the overall deformation of the tailings ponds was predominantly subsidence,with the maximum cumulative line-of-sight deformation over three years ranging from-55 mm to-167 mm.Deformation was mainly concentrated in the tailings accumulation area,while the dam structures remained relatively stable.Among them,the Xiagao Iron Mine tailings pond exhibited the most significant subsidence.[Conclusions]SBAS-InSAR technology can effectively capture surface deformation information of tailings ponds under the complex environmental conditions in South China,providing an effective regional-scale monitoring tool for tailings pond safety monitoring and risk identi-fication.关键词
