摘要: 针对利用合成孔径雷达干涉测量技术(InSAR)难以获取矿区大量级沉陷信息的问题,本文提出了一种融合实测数据的大量级沉陷InSAR监测方法。该方法首先计算矿区时序InSAR累计沉降盆地,然后基于InSAR最大形变监测梯度确定融合边界,最后利用反距离权重插值方法将实测数据和InSAR监测结果融合,完整获取矿区的大量级沉陷盆地。以山东某矿3308工作面为研究区域进行监测,并对该方法的可行性和精度进行了验证。结果表明,该方法提取的矿区大量级沉陷盆地连续完整,空间位置和形态特征与实际开采情况相符,与水准实测数据相比,融合结果的平均误差和均方根误差分别为73.2和111.6 mm,可获取更为完整准确的矿区沉陷信息。

Abstract: Aiming at the problem that interferometric synthetic aperture radar (InSAR) technology is difficult to obtain the information of large-scale subsidence in mining area, an InSAR monitoring method for large-scale subsidence by integrating the measured data proposesed.Firstly, the time-series InSAR accumulated subsidence basin in the mining area is calculated. Then the fusion boundary is determined based on the maximum deformation monitoring gradient of InSAR. Finally, the inverse distance weighting interpolation method is used to integrate the measured data and the InSAR monitoring results to obtain the large number of subsidence basins in the mining area. Taking the 3308 working face of a mine in Shandong province as the research area verify the feasibility and accuracy of the method. The results show that, the large-scale subsisional basins in the mining area extracted by this method are continuous and complete, and the spatial location and morphological characteristics are consistent with the actual mining situation. Compared with the horizontal measurement data, the average error and root mean square error of the fusion results are 73.2 and 111.6 mm respectively, which can obtain more complete and accurate subsisional information in the mining area.

Key words: large-scale subsidence, InSAR, measured data, subsidence basin
