摘　　要：为了能够精准监测条带开采地表沉陷情况,验证SBAS-InSAR技术在条带开采地表沉陷监测中的可行性与精度,利用SBAS-InSAR技术对2019年6月-2022年2月的33景Sentinel-1A升轨SAR影像进行干涉时序处理,得到了监测期条带开采地表沉陷特征。并结合监测期的地表水准测量数据对SBAS-InSAR监测结果进行了验证分析。结果表明,SBAS-InSAR技术能够有效监测到条带开采地表沉陷特征及沉陷量,监测精度满足规范要求,为矿区“三下”压煤开采提供了技术支撑。In order to accurately monitor surface subsidence in strip mining and verify the feasibility and accuracy of SBAS-InSAR technology in surface subsidence monitoring in strip mining,33 Sentinel-1A ascending orbit SAR images from June 2019 to February 2022 were interferentially processed by SBAS-InSAR technology.The surface subsidence characteristics of strip mining during the monitoring period are obtained.Combined with the surface leveling data of the monitoring period,the monitoring results of SBAS-InSAR were verified and analyzed.The results show that the SBAS-InSAR technology can effectively monitor the surface subsidence characteristics and subsidence amount of strip mining,and the monitoring accuracy meets the requirements of the code,which provides technical support for the mining area of"three-down"coal mining.
