摘　　要：针对煤炭资源的长期无节制开采,造成矿区地表沉降、塌陷、环境污染等诸多问题,本文基于小基线集(SBAS-InSAR)技术,使用Sentinel-1雷达数据,对鹤岗矿区进行形变监测,分析2017年3月26日至2021年12月18日期间地表形变和时空演化特征。结果表明,鹤岗矿区地表形变严重,形变量在监测期内逐渐增大,最大累计形变量达到-585 mm。空间分布上,相较于2013—2016年,振兴矿、新岭矿地表形变有减缓趋势,峻德矿有向南扩展趋势。In view of the long-term uncontrolled mining of coal resources,which has caused a series of problems such as surface sub-sidence,collapse and environmental pollution in the mining area,this paper uses the small baseline subset(SBAS-InSAR)technolo-gy and Sentinel-1B radar data to conduct deformation monitoring in Hegang mining area,and analyze the surface deformation and spa-tio-temporal evolution characteristics from March 26,2017 to December 18,2021.The results show that the surface deformation of Hegang mining area is serious,and its shape variable increases gradually during the monitoring period,with the maximum cumulative shape variable reaching-585mm.In terms of spatial distribution,the surface deformation of Zhenxing and Xinling mines has a slowing trend,while Junde mine has a southward expanding trend compared to 2013 to 2016.
