摘　　要：笔者基于SBAS-InSAR技术对蛟河矿区地表沉降进行监测,获取地表沉降速率和累积沉降结果,结合精度和野外调查验证了监测结果的可靠性,分析了蛟河矿区地表沉降的时空演化态势。结果表明,在2017年1月至2021年12月监测期间,蛟河矿区发生了较为严重的地面沉降,主要聚集性分布于红胜村、工业村和建设村一带,其中位于红胜村的沉降区S1沉降最为严重,沉降面积占蛟河矿区沉降总面积的58.02%,最大沉降速率为-99.64 mm/a,最大累积沉降量为-499.7 mm,其南侧红胜村所处区域平均沉降速率达-80 mm/a以上。The authors utilized SBAS-InSAR technology to monitor surface subsidence in the Jiaohe mining area,obtaining surface subsidence rates and cumulative subsidence results.The reliability of the monitoring results was verified through accuracy assessments and field investigations,allowing for an analysis of the spatio-temporal evolution patterns of surface subsidence in the area.The results indicate that during the monitoring period from January 2017 to December 2021,significant surface subsidence occurred in the Jiaohe mining area,primarily concentrated around Hongsheng Village,Gongye Village,and Jianshe Village.The subsidence zone S1,located in Hongsheng Village,experienced the most severe subsidences,accounting for 58.02%of the total subsidence areas in the Jiaohe mining area,with a maximum subsidence rate of-99.64 mm/a and a maximum cumulative subsidence of-499.7 mm.The average subsidence rate in the southern part of Hongsheng Village exceeded-80 mm/a.
