利用InSAR技术监测徐州市矿区地表变形

徐州煤矿资源丰富，煤矿的开采和利用，在产生巨大经济和社会效益的同时，却造成了大规模的地面沉陷，区内大量的农田、建筑物、道路等受到影响和破坏。InSAR测量技术的差分干涉图用于监测厘米级甚至更微小的地面形变，具有全天候、大面积监测地面沉陷的优势。以徐州地面沉陷监测为例，介绍了InSAR测量技术在矿区地面沉陷监测领域中的实际应用。

Surface deformation monitoring with InSAR technology in Xuzhou

The coal resource in Xuzhou was rich. When the coal exploitation and utilization brought enormous economic and social benefits to the local people, it caused severe ground subsidence as well, affected the farmland, and damaged the buildings and roads. The radar image of differential interferometry technology (InSAR) could be able to detect the crustal deformation at centimeter scale or even more accurate. It had the advantages of all weather and wide area in monitoring settlement of subsidence of mine. Based on the monitoring of ground subsidence in Xuzhou mine, the authors introduced the application of InSAR technology in ground subsidence.
