摘　　要：采用时序InSAR技术对某煤矿2个采煤工作面导致的地面塌陷进行了形变监测,利用干涉效果较好的开挖公路区域实现对采煤塌陷区较好的监测效果。采用2016年6月～12月期间共计8景RADARSAT-2数据,利用小基线集技术处理得出采煤沉陷区地表形变速率及时序累积形变结果,通过与采煤工作面的时间空间分布情况对比,研究得出时序InSAR对采煤塌陷具有较好的指示作用,InSAR监测采煤沉陷区变形结果与采空区的范围对应良好。In order to study the problem of deformation monitoring in coal mining subsidence area, the deformation monitoring work of a coal mining subsidence area caused by 2 coal mining faces was carried out by InSAR technology. The better monitoring effect of coal mining subsidence area was realized by using the excavation highway area with the better interference effect. With a total of 8RADARSAT-2 image pairs from June 2016 to December 2016, the result of time series cumulative deformation and strain velocities of coal mining subsidence area were obtained by using SBAS technique to deal with data processing. By comparing the results of InSAR processing with the time and space distribution of coal face, can get a conclusion that the InSAR monitoring deformation results of coal mining subsidence area correspond well with the goaf area.
