采矿引起地面沉陷是矿区经常发生的一种破坏性灾害。作为空间对地观测技术的一个重要分支——合成孔径雷达干涉测量技术,可以实现高精度大范围的矿区开采沉陷监测,越来越受到人们的重视。采用“两轨法”差分干涉测量技术对矿区开采沉陷监测进行了试验研究,提取了垂直形变图,分析了试验区开采沉陷随时间变化的规律,并对沉陷区作了剖线分析。
The ground subsidence caused by mining is one kind of disastrous damage happened frequently in mining areas. As an important branch of space-to-earth observation technology, interferometric synthetic aperture radar (InSAR) can implement high-precision, large-scale mining subsidences monitor, and attract more and more people's attention. In this paper, authors used "two-pass" differential InSAR techniques to do an experimental study of mining subsidence monitor in mining area, and withdrew the vertical deformation chart. Authors also analyzed mining subsidence change law with the time and made a postmortem analysis.
