【摘要】 以安徽恒源煤电(皖北)的钱营孜煤矿为试验区,利用两景L波段的ALOS PALSAR影像,采用"两轨法"差分干涉技术获取了该矿区在2010年1月13日到2月28日间的地面沉陷信息,并与同一时期该矿区地面监测站所获取的沉降变形数据进行了比较。结果表明,与地面站水准测量的结果一致,说明使用该技术能很好地完成监测平原地带的煤矿区地面沉陷的任务。更多还原

【Abstract】 Taking Qianyingzi coal mine of Anhui Hengyuan Coal-Electricity Group(North of Anhui) as the experimental district,the surface subsidence information in this area during Jan 13 to Feb 28 in 2010 was obtained by two scenes ALOS PALSAR image of L band and by way of "two pass" D-InSAR,which were compared with subsidence and deformation data from the ground monitoring station at the same period.The results show that it is correspond with the leveling measurement at ground monitoring station,and this technique can perfectly fulfill the monitoring task of ground subsidence in coal mine of plains.更多还原
