摘要随着InSAR技术的发展，其应用领域得到了不断地的拓展，越来越多的学者将InSAR技术应用到了矿区的地表沉陷监测中。本文采用9景ALOS PALSAR数据，利用二轨差分干涉技术对张小楼矿区进行地表沉降监测，实验得到了张小楼矿时间序列的地表沉降信息，得到以下结论：72341
（1）自2007年2月20号至2011年1月16号期间，地表总的下沉量约3290mm。后续时间间隔较短的干涉对，如2008年1月8号到2008年2月23号期间，干涉效果良好，所得下沉盆地明显，最大下沉约60mm。2008年4月9号到2009年1月10号，受时间失相关影响，下沉盆地整体效果不明显。随着开采的进行，下沉盆地范围有所变化，如2009年1月10号到2009年2月25号期间，下方下沉盆地中心有向东南方向移动的趋势。随着开采的结束，下沉速度有所减小，如2009年2月25号到2010年1月13号期间，下沉约596mm,平均下沉速度1。85mm/d。
（2）地面观测站数据和D-InSAR技术获得的下沉值对比分析表明：两者监测结果在量值上误差为厘米级，且两者形变趋势具有高度一致性，证明了D-InSAR技术在矿区地表形变监测中的可行性与可靠性

Ground Deformation Monitoring and Analysis of Mining Area in Xuzhou City Zhang Xiaolou Based on InSAR Technique
Abstract With the development of InSAR technology, and its applications have been continuously expanding, More and more scholars put the InSAR technology applied to the surface subsidence monitoring in mining area。 In this paper, 9 King ALOS PALSAR data, the use of two-track differential interferometry technique Zhang small building ore ground subsidence monitoring。 Zhang experiments small building surface mine subsidence time series information, the following conclusions:
(1) From 20 February 2007 to 16 January 2011, the total sinking about 3290mm。 Subsequent intervals shorter interference in, such as From 8 January 2008 to 23 February 2008, the interference effect is good, obviously resulting subsidence basin, the largest sink of about 60mm。 From 29 April 2008 to 10 January 2009, by the time of the loss related to the impact, the overall effect is not obvious subsidence basin。 As mining progresses, the range of basin subsidence change, such as the period 10 January 2009 to 25 February 2009, sinking below the center of the basin there is a tendency to move to the southeast。 With the end of mining, sinking speed has been reduced, such as the period 25 February 2009 to 13 January 2010, sinking approximately 596mm, average sinking speed 1。85mm / d。
(2) According to the ground-based data and D-InSAR technique comparison analysis shows that the subsidence value obtained D-InSAR technology in monitoring the earth's surface deformation with reliability, proved that the use of D-feasibility of InSAR technology in surface mining subsidence monitoring。
