摘　　要：【目的】煤炭资源的开采引发一系列的生态环境问题,地面塌陷问题尤为严重,而地表形变监测是修复生态环境问题的首要工作。【方法】InSAR技术作为一种面监测技术,已成功应用到煤矿地面塌陷监测中,本研究利用雷达差分干涉测量(D-InSAR)技术,计算2020年8月至2022年10月间共31景Sentinel-1A数据。【结果】在监测期内,开采工作面的地表共形成3个形变中心,分别位于301和303盘区的工作面,地表在煤矿开采后进入快速形变期,之后开始缓慢形变,直至趋于稳定状态。【结论】D-InSAR技术对于此类地面塌陷问题,相较于点监测技术,具有先天的优势,能够快速、准确地获取整个工作面的形变情况,对煤矿生态环境问题的改善起到了指导作用。[Purposes]The mining of coal resources has caused a series of ecological and environmental problems,and among them,the problem of ground collapse is particularly serious,and the monitoring of surface deformation is the primary work to repair ecological environment.[Methods]InSAR technology has been successfully applied to the monitoring of coal mine surface collapse as a surface monitoring technology,and 31 Sentinel-1A data fromAugust 2020 to October 2022 were calculated by using radar differential interferometry(D-InSAR)technology to monitor surface deformation in Yanghuopan Coal mine in this paper.[Findings]During the monitoring period,according to the monthly shape variables obtained by D-InSAR technology,three deformation centers were formed,which were located in the working face of the 301 and 303 panels respectively,and the surface of the coal mine entered the rapid deformation period after mining,and then began to deform slowly until it reached a stable state.[Conclu-sions]D-InSAR technology has a congenital advantage over point monitoring technology for this kind of ground collapse problem,which can quickly and conveniently obtain the deformation of the whole work-ing face,and plays a reference role in improving the ecological environment monitoring..
