摘　　要：合成孔径雷达差分干涉测量技术具有空间分辨率高、全天时、覆盖面积大以及成本低等优势,已成为矿区地表沉陷监测的主要方法之一。以河北省邯郸市某矿区为例,收集了2015年4月至2015年12月覆盖研究区的C波段的RADARSAT-2卫星影像作为数据源,采用双轨D-InSAR对数据进行处理,通过影像配准、干涉图生成、DEM处理、去除残余相位、地理编码等,结合GIS建立地表形变图,同时在矿区开采工作面中间位置选择一条特征线,提取2015年4月至2015年12月影像地表沉陷散点图,并选取2015年12月的沉降量和实际水准数据进行对比分析。结果表明:在开采过程中地表沉陷在-22~5mm之间,D-InSAR监测具有较高的精度,能为矿山的安全、绿色、高效开采提供可靠的数据支撑。Synthetic aperture radar(SAR)differential interferometry has the advantages of high spatial resolution,all-day time,large coverage area and low cost and has become one of the main methods to study the monitoring of surface subsidence in mining areas.Taking a mine in Handan,Hebei as an exanple,the image surface subsidence scatter plot from April 2015 to December 2015 is extracted and the settlement and actual level data in December 2015 are selected by collecting the C-band RADARSAT-2 satelite imagery covering the study area from April 2015 to December 2015 as a data source,data processing with two-pass D-InSAR,image registration,interferogram generation,DEM processing,removal of residual phase,geocoding,combined with GIS to establish a surface deformation map and selecting a feature line in the middle of the mining face in the mining areas for comparative analysis.The research results show that during the mining process,the surface subsidence is between-22 mm and 5 mm,and the maximum subsidence value is 22 mm.It can be seen that the D-InSAR monitoring has a high accuracy and can provide reliable data support for safe,green and efficient mining of mines.
