摘　　要：采空塌陷评价一直是地质灾害评价的难点和重点,随着遥感技术等新技术手段的发展,InSAR技术近些年来以其独有的优势,在城市区域地表形变方面应用效果突出。本文以淮南市潘集区为例,以87景完整覆盖潘集区的Sentinel-1卫星IW模式高分辨率影像为数据源,基于PS-InSAR技术,对潘集区2017—2022年的地表形变特征进行了精细化获取,最终对潘集区的采空塌陷范围和沉降量进行了评价,该项工作对今后在类似地区利用InSAR技术进行采空塌陷评价具有指导意义。Mining-induced ground subsidence evaluation has always been a difficult issue and focus in geological hazard evaluation.With the development of new technologies such as remote sensing technology,InSAR technology,with its unique advantages,has been applied more effectively in urban surface deformation in recent years.Using 87-scene Sentinel-1 satellite IW mode high-resolution images fully covering Panji District as data sources,based on PS-InSAR technology,this paper obtains fine features of surface deformation in the Panji District from 2017 to 2022,and then evaluates the range and amount of subsidence in the district,providing a reference for use of InSAR technology to evaluation of mining-induced ground subsidence in similar areas in the future.
