基于D-InSAR的大通煤矿地表形变监测应用研究

Research on Datong coal mine surface deformation monitoring based on D-InSAR

本文以大通煤矿地表形变监测为依托,利用雷达差分干涉测量(D-InSAR)技术,获得2013-10至2014-04连续五期的SAR影像监测图,在6个月间隔里出现了2处沉降漏斗区域,并且沉降漏斗区域与矿区分布一致,并与GPS形变监测相互对比,发现两种监测方法结果相互符合,说明D-InSAR能够有效监测矿区地表形变。

For Datong surface deformation monitoring, five consecutive SAR images from October 2013 to April 2014 are used to take D-InSAR and two subsidence funnel areas are detected. The subsidence funnel areas are consistent with the mine distribution, and agree with the results of GPS deformation monitoring. It proves that the D-InSAR can effectively monitor surface deformation.
