Application of Satellite Radar Interferometry to the Examination of the Areas of Mining Exploitation

摘要

A constant development of remote sensing technology makes it possible to get more diverse information about phenomena, which used to be the focus of other scientific disciplines. One of such techniques is SAR (Synthetic Aperture Radar) Interferometry, InSAR in short. The image obtained thanks to this method (the interferogram) enables us to observe the height changes of the terrain surface. At first, interferograms were used to observe the movements of the Earth crust caused by the deformations of continental plates edges and earthquakes. The usefulness of the interferometric images in observation of the changes in the terrain of underground exploitation has been proved very early. The first research in Poland was undertaken in 1997 in the Industrial District of Upper Silesia (PERSKI 1998). This research confirmed a high veracity of the interferometric data and their exceptional usefulness in the environmental monitoring as well as in detecting the dynamics of land subsidence caused by underground mining exploitation. The next research was carried out on the copper ore exploitation field in the vicinity of Legnica (KRAWCZYK, PERSKI 2000). Presently the research is being carried out to establish the possibility of monitoring dislocations with large-scale drainage troughs.
