Monitoring and Analysis of Surface Deformation in Yanghuopan Mining Area Based on D-InSAR Technology
[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..
