摘要
近年来,将InSAR技术应用于地表监测成为研究的热点。为确定煤矿采空区历年地表沉降情况,采用PS-InSAR技术,利用历史存档降轨数据,提取研究区不同时期地表变形速率图。结果表明,PS-InSAR技术能够获得采空区地表毫米级变形监测结果。
In recent years,the application of InSAR technology on surface monitoring has become a research hotspot.In order to determine the surface subsidence of the coal mine gob over the years,the PS-InSAR technology was used to extract the surface deformation rate maps in different periods of the study area using historical archived orbit reduction data.The results show that PS-InSAR technology can obtain the monitoring results with millimeter-level deformation for the goaf.
