| 摘 要： | 徐州煤矿资源开采已造成了大规模的地面沉陷,为了为矿区安全开采和塌陷区环境综合治理提供科学依据,利用雷达差分干涉测量（DInSAR）技术对ALOS PALSAR数据进行处理,获得徐州张双楼煤矿区2011-01-16至2011-03-03期间的地表形变分布图.结果表明,张双楼煤矿在46 d间隔里出现了3处沉降漏斗区域,漏斗中心最大沉降量达到420mm,并且沉降漏斗区域与矿区分布一致,说明DInSAR能够有效地监测矿区地表形变.

| Abstract: | Heaving mining in Xuzhou City has seriously affected the local geological environment,which is manifested by large-scale ground subsidence.In order to provide a scientific basis for ensuring mining safety and managing the environment of subsidence area,the DInSAR （differential synthetic aperture radar interferometry） technology is used to acquire the information of the subsidence area during January 16,2011 to March 3,2011.Two ALOS PALSAR data are used to generate deformation interferograms,and the result shows that Zhangshuanglou coal mining area has formed three subsidence funnels during the satellite＇s revisit period （46 days）.The largest settlement of the funnel center has reached to 420 mm,in which the distributions of subsidence funnels area and the mining area are also consistent.The results indicate that DInSAR technology is an effective method to monitor the mining area subsidence. |
