基于DInSAR技术的矿区形变监测

Deformation Monitoring of Mining Area Based on DInSAR Technology

本文以大柳塔煤矿某工作面为实验区,采用高分辨率Terra SAR-X的13景数据,运用GAMMA软件进行时间序列的合成孔径雷达差分干涉测量(DIn SAR)实验,获取了从监测期间的开采沉陷时序关系图,并与同步获取的GPS观测结果进行对比验证,结果证明,DIn SAR监测结果与GPS测量结果具有较高的一致性。研究表明,利用DIn SAR监测技术监测矿区地面沉降,具有较广阔的应用前景。

This paper uses a working face of Daliuta coal mine as an experimental area, using 13 high reso- lution TerraSAR-X scenes, makes an experiment of time series of Differential Interferometry Synthetic Aper- ture Radar （DInSAR） with GAMMA, Obtains the mining subsidence sequence diagrams during the monitor- ing, compares with synchronous GPS observations. DInSAR monitoring Results has high consistency with GPS measurement Studies The research shows that DInSAR monitoring technology to monitor mining subsid- ence has broad application prospect.
