D-InSAR监测开采沉陷的实验研究

Experimental Research on Monitoring Mining Subsidence by D-InSAR Technique

基于ERS1/2影像,针对沛城矿二二采区,利用DOR IS软件进行了D-InSAR处理,得到该采区的下沉值,并在与实测下沉值进行对比后,得到了实测和D-InSAR监测下沉值之间的差值与距离的关系式,根据该关系式对D-InSAR监测下沉值进行修正,获得了与地面实测相近的地面下沉,从而证明D-InSAR用于开采沉陷监测是可行的。

Based on ERS1/2 images,and in view of the No.22 Mining Area of Peicheng Mine,DORIS were chosen for D-InSAR（Differential Interferometric Synthetic Aperture Radar） process to monitor the mining subsidence in Er er mining area of Peicheng by the Doris software in this paper,and the subsidence values were obtained.After compared with the surface observation data,the relationship between the surface observation data and the results obtained by D-InSAR technique were established.According to the formulations,the subsidence values obtained by D-InSAR technique were modified, the land subsidence values closed with the surface observation data were calculated, and this proves that using D-InSAR tech- nique to monitor the mining subsidence are very, reliable.
