摘要
为了分析矿区上方铁路地表的形变,文中应用双轨法D-In SAR技术对10景高Sentinel-1A影像进行处理,获得了20150926—20160523时段内近采区上方铁路附近的地表变形;同时结合开采沉陷预计结果对矿区开采的地表沉陷情况进行分析,并利用矿区地表移动观测站实测数据进行验证;结果表明D-InSAR技术可以有效地对矿区上方铁路附近地表形变进行监测。
In order to analyze the surface stability of the railway above the coal pillar in the mining area, the 10 Sentinel-1A images of high resolution were processed based on the double D-InSAR technology, the surface deformations were obtained during the period of 20150926 to 20160523; at the same time, the surface subsidence of mining area was analyzed with the prediction results of mining subsidence, and the measured data of surface movement observation station were verified; the results showed that D-InSAR technology could be used to monitor the surface deformation near the railway above the coal pillar.
