雷达差分干涉测量（D-InSAR）技术一种新兴的地表形变监测技术，具有精度高、监测范围广等特点。本文以甘肃平凉华亭煤矿为例研究该技术在矿区的应用，首先采用两轨法D-InSAR技术获取了矿区在2007-2010年的地表形变场，然后分析了InSAR地表形变场的特点。结果表明D-InSAR技术监测到的沉陷信息可以较为准确的反映矿区实际沉陷状况，可以作为一种获取大范围煤矿区的地表沉陷的有效方法。%Differential Synthetic Aperture Radar interferometry (D-InSAR) is a newly developed technique for monitoring ground deformation with some prominent advantages such as high accuracy and wide range monitoring. This paper obtained the deformation of the Huating mining area in 2007-2010 by the two-pass D-InSAR technology, and then analyzed the deformation field. The results showed that D-InSAR technology for monitoring mining collapse can accurately reflect the actual conditions, and can be as an effective way to get wide range of mining collapse.
