中文摘要：
介绍了InSAR技术在矿区地表形变监测中的应用现状及进展,分析了D-InSAR技术相比于传统测量手段的优势,并指出其在矿区地表形变监测中的不足。针对传统D-InSAR技术的局限性,重点讨论了短基线（SBAS）、永久散射体（PS）和角反射器（CR）等高级差分干涉技术,并结合矿区沉降监测实例,分析了其特点与应用现状,讨论了现有研究中仍存在的问题。高级InSAR技术和高分辨率SAR影像的结合将是矿区地表形变监测的发展趋势。
英文摘要：
The application status and research progress of InSAR technique in the monitoring of the ground surface deformation in mining area were introduced.Firstly,the advantages of D-InSAR technique were analyzed by comparing to the traditional surveying methods.Then,the limitations of D-InSAR in the mining deformation detection were described.According to the limitations of the traditional D-InSAR method,the advanced InSAR technique,e.g.,small baseline subset（SBAS）,permanent scatterer（PS） and corner reflector（CR） techniques were discussed.Using real mining subsidence monitoring as example,the characteristics and application status of those advanced InSAR techniques were studied,and the key problems still existing in the current research were summarized.Finally,it is indicated that the development trend of InSAR monitoring surface deformation in mining area is the combination of advanced InSAR and high-resolution SAR images.
