| 摘 要： | 针对常规的通过大地水准测量、GPS测量监测矿区地面沉陷的技术存在监测周期长、成本高、无法全面监测等缺陷,提出了一种基于D-InSAR技术的矿区地面沉陷监测方法。以淮南矿区为试验区,采用两轨法D-InSAR技术,利用该地区2个时相的ALOS PALSAR数据获取了淮南矿区试验时间段内的地面形变图,分析了淮南矿区各矿的地面沉陷信息。结果表明,煤矿开采区存在5~25 cm不同程度的沉陷,与实际情况相符,因此,基于D-InSAR技术的监测方法可以作为一种获取矿区大范围的地表沉陷信息的有效方法。

| Abstract: | In view of defects of long monitoring period,high cost and incomprehensive monitoring existed in monitoring technology of surface subsidence in mining areas by use of geodesic leveling and GPS measurements,a monitoring method of surface subsidence based on D-InSAR technology was proposed.Taking Huainan Coal Mining Area as experimental district,two-pass D-InSAR technology was used to get surface deformation image of Huainan Coal Mining Area in experimental time by use of experimental data of two scenes ALOS ... |
