摘要
合成孔径雷达差分干涉测量(Differential interferometry synthetic aperture radar,D-InSAR)技术在矿区地面沉降监测领域具有独特的优势和巨大的发展潜力。为分析并掌握济宁某矿区地面沉降的变化状况,选取具备高穿透植被能力的L波段的ALOS PALSAR数据,基于双轨D-InSAR技术对采煤塌陷进行动态监测,获取矿区的形变信息,并与水准数据进行对比分析,进而为有效的进行矿山地质环境保护与治理恢复提供一定的理论依据和技术支持。
D-InSAR (Differential interferometry synthetic aperture radar) technology has unique advantages and great development potential in monitoring the subsidence of mining areas. In order to analyze and obtain the changes of the ground subsidence in the Jining mining, ALOS PALSAR data in L-band with high vegetation penetration capacity are selected to conduct dynamic monitoring of coal mining collapse based on two-track D-InSAR technology to obtain the subsidence information. Moreover, the monitoring results are compared with the leveling data. Furthermore, it provides theoretical basis and technical support for effectively protecting and restoring the mine geological environment.
