基于D-InSAR监测的黄土矿区地表沉陷特征分析
|
摘要
合成孔径雷达差分干涉测量(D-InSAR)技术是20世纪90年代发展起来的微波遥感技术,具有高精度地监测地表微小变形的能力,已经成为矿区地表沉陷监测的有效技术手段。以陕西彬长矿区为研究区,利用多期SAR影像数据,应用D-InSAR技术方法开展地表沉陷监测实验,并结合矿区的实际情况,对矿区下沉等值线图进行简要分析。实验发现3种矿区工作面均发生了不同程度的沉陷变形,其中沉降量最大值出现在亭南煤矿304工作面内,达到17.5 cm.结果表明:D-InSAR技术可以反映出矿区沉陷位置和下沉程度,展示出D-InSAR技术在黄土矿区地表沉陷监测方面具有良好实用性和广泛应用前景。
Synthetic Aperture Radar Differential Interferometry(D-InSAR) technology is a microwave remote sensing technology developed in the 1990 s. It has the ability to monitor surface micro-deformation with high precision and has become an effective technical means for monitoring surface subsidence in mining areas. Taking the Binchang mining area in Shaanxi as the research area, using the multi-period SAR image data, the D-InSAR technology method was used to carry out the surface subsidence monitoring experiment, and combined with the actual situation of the mining area, the sinking contour map of the mining area was briefly analyzed. The experiment found that the working faces of the three mining areas have experienced different degrees of subsidence deformation, and the maximum settlement amount appears in the 304 working face of the Tingnan Coal Mine, reaching 17.5 cm.The results show that D-InSAR technology can reflect the location and subsidence of mining area, and demonstrates that D-InSAR technology has good practicability and wide application prospects in surface subsidence monitoring in loess mining area.
