基于融合多视和全分辨率的矿区沉降监测

    Mining Subsidence Monitoring Based on Combination Method of Multi-Look and Full-Resolution Interferogram

    • 摘要: 针对矿山开采沉降幅度大、范围小的特点,提出融合多视和全分辨率监测矿区沉降的方法。以济宁矿区为研究区,选取2景高分辨率的TerraSAR-X影像,分别采用多视和全分辨率方法获取研究区内2017年2月17日—3月11日的沉降情况;将两者得到的结果进行融合,即采用多视方法监测下沉盆地边缘较小的沉降,采用全分辨率方法监测下沉盆地中心的大梯度沉降。结果表明:在这期间济宁矿区最大沉降出现在新驿煤矿,最大沉降量达到 -74 mm,最大沉降速率达到 -3.36 mm/d。

       

      Abstract: In view of the characteristics of mining subsidence with large amplitude and small scope, a method of mining subsidence monitoring by combining multi-look with full-resolution interferogram is put forward. Firstly, Jining Mining Area is selected as the research object and two high resolution TerraSAR-X images are obtained. Next, the subsidence of Jining Mining Area from February 17, 2017 to March 11, 2017 was obtained respectively by multi-look and full-resolution interferogram method. The results obtained by the two methods are fused, i.e., the multi-look method is used to monitor the small subsidence at the edge of the sinking basin and the full-resolution method is adopted to monitor the large gradient deformation at the center of the sinking basin. The results show that the maximum subsidence of Jining Mining Area occurs in Xinyi Coal Mine, the maximum subsidence amount is -74 mm and the maximum subsidence rate is -3.36 mm/d.
