摘　　要：合成孔径雷达差分干涉测量(Differential Interferometic SAR,D-InSAR)技术可以快速、精确、大范围地监测地表形变,为矿区开采沉陷的监测和防治提供了有效手段。以安徽淮南淮河以北矿区为研究区,获取了3景高分辨率TerraSAR-X影像,分别利用二轨法、三轨法D-InSAR技术提取2010年11月22日~2011年4月25日的沉陷情况。结果显示:在这期间淮南矿区发生了大量沉陷,最大沉陷量为-71mm,位于丁集矿区;顾桥顾北矿区和潘集矿区的最大沉陷量约为-50和-45mm,两种方法提取出的沉陷区位置、形态与实际情况基本稳合,沉陷速率与相关研究大体一致,表明利用短时空基线的高空间分辨率TerraSAR-X数据能够对淮南矿区的地表形变量和形变范围进行高精度的监测。同时,将两种方法提取的结果对比分析发现,在缺乏精细DEM数据的情况下,三轨法在平原区的应用效果优于二轨法。D-InSAR technique can monitor surface deformation fast, accurately and on a large scale. It pro vides an effective means for monitoring and controlling the mining subsidence in mining area.This article takes the Huainan mining area to the north of the Huaihe river in Anhui Province as the research region. Using three scenes high resolution TerraSAR-X images, subsidence information is extracted by two-pass D-InSAR and three-pass D-InSAR during 2010.11.22 and 2011.01.25.The results show that,during the pe- riod,Huainan mining area was observed large settlement. The maximum settlement of the research area was -71 mm,which was located in Dingji mining area;the maximum settlement in Guqiao and Gubei min- ing area and Panji mining area was respectively --50 mm and --45 mm.The position and shape of subsid- ence area using the two D-InSAR method was relatively well identical to the actual situation.Furthermore, settlement rate was broadly consistent with the relevant research. It suggests that , based on high spatial resolution TerraSAR-X data of short temporal baseline, deformation of the earth and deformation range can be monitored with high precision in Huainan mining area.At the same time,by making a comparative anal- ysis with the two methods, it finds that, under the circumstances of no high accuracy DEM, application effect of three-pass D-InSAR is better than that of two-pass D-InSAR in plain area.
