摘　　要：合成孔径雷达差分干涉测量(DInSAR)是近年来发展起来的一种监测地表形变的技术手段,在矿区地表沉降监测方面取得了较好的应用。针对DInSAR技术中存在的轨道误差和与地形相关的大气延迟,利用双二次模型和线性模型对其进行联合模拟并进行去除。为了有效监测山西省阳泉矿区地表形变,使用7幅Sentinel-1A影像采用DInSAR方法获取了该地区在2016年11月26日至2017年2月6日期间的地表沉降。结果显示,研究区内整体表现为沉降趋势,沉降漏斗位置分布与矿区位置较为一致;新景矿内2个区域在72 d内的最大累积沉降分别达到-18.82、-22.33 cm。Differential interferometry synthetic aperture radar（DInSAR） is a new measuring technique developed in resent years to monitor the deformation of ground surface, which has been applied successfully in many applications including mining areas. In this paper, 7 ascending Sentinel-1 A images from November 26, 2016 to February 6, 2017 are used to monitor the deformation of mining areas in Yangquan Mining Area using DInSAR technique. To effectively monitor surface deformation of the mining areas,the orbit error and topographically-related atmosphere delay that were not well dealt with in the DInSAR technique have been corrected by combining a bi-quadratic model and a linear model. The experimental results show that the overall of the study area is the subsidence tendency and the distribution of funnel-shaped subsidence is consistent with the location of the mining areas.Within a period of 72 days, the maximum cumulative settlement of the two areas in Xinjing Mining Area is-18.82 cm and-22.33 cm respectively.
