基于D-InSAR的彬长矿区沉陷变形监测
|
摘要
差分雷达干涉测量(D-InSAR)技术能够监测沉陷区空间连续曲面的形变,具有精度高、连续监测、成本低等特点,是对现有矿区地表沉陷监测方法有益的补充。以陕西彬长矿区为例,根据获取的雷达影像图开展干涉测量的研究,将形变前后2幅干涉图相位差分得到地表形变,对照矿区的实际情况,分析去相干源影响,并对其误差作了简要分析。结果表明:D-InSAR技术,能够准确反映出矿区沉陷的位置和下沉程度,尤其在黄土高原,地质地貌条件比较复杂的条件下,更展示出D-InSAR技术在矿区地面沉降监测适用性、优越性和实用价值。
D-InSAR could monitor the space continuous surface deformation in subsidence area.It is a useful supplement to the traditional subsidence monitoring methods because of its high accuracy,continuous monitoring and low cost characteristics.The paper studies the interferometric based on the acquired radar images of Binchang mining area in Shaanxi province,gets the small deformation from difference phase in interferogram before and after deformation,analyses the impact of coherent sources according to the actual situation of the mine area and its errors.Eventually,the paper comprehensively analyses the deformation data from the images according to the theory of mining subsidence and practical situation of the mine.Results show that: D-InSAR technology,can accurately reflect coal mining subsidence position and sinking degree,especially in the loess plateau,geological and geomorphic conditions which is more complexity,the D-InSAR technology shows more applicability,advantages and practical value in mining subsidence monitoring.
