基于D-InSAR技术的矿区沉降监测研究
|
摘要
以淮南某矿区为例,采用二轨法合成孔径雷达干涉测量(D-InSAR)技术,利用基于ENVI遥感图像处理平台的SARscape软件处理两景ALOS遥感单视复数影像数据,获取该矿区2007年12月10日—2008年1月25日时段的历史变形场。实验结果表明:对沉降矿区进行水平、垂直剖面沉降分析,可以看出该时段矿区最大沉降达到282 mm,日沉降速率约6 mm/d,按照1.67 mm/d的稳定判别标准可知沉降区处于活跃阶段;沉降曲线为漏斗形状,符合矿山开采地表沉陷变形规律。该研究成果对监测矿区开采地表沉陷信息具有重要参考价值。
Has become one of the most potential ground observation techniques with its ability to monitor surface deformation all day, all day, wide coverage and high precision. Taking a mining area in Huainan as an example, this paper uses the two tracking method Differential Interferometric Synthetic Aperture Radar(D-InSAR) technology to process the ALOS data of two sceneries with SARscape software based on ENVI, and obtains the historical deformation field of the mining area during the period of 2007.12.10 to 2008.01.25. The experimental results show that: Firstly, the settlement of the horizontal and vertical sections of the settlement mining area shows that the maximum settlement of the mining area reaches 282 mm and the daily settlement rate is about 6 mm/d. According to the stability criterion of 1.67 mm/d, the subsidence area is in an active stage.Secondly, the settlement zone line is in the shape of a funnel, which conforms to the law of mining surface subsidence and deformation. The research results of this paper have important reference value for monitoring mining surface subsidence information in mining area.
