摘要
本文运用SBAS-InSAR时序技术,对2019年9月19日—2020年3月29日期间的17景Sentinel-1A数据进行处理,获取了济宁北部煤矿区内的年均沉降速率,探测到6处沉降漏斗分布,最大沉降速率达到-242mm/y。结果表明:SBAS-InSAR时序方法可在矿区的地表形变监测中得到足够的监测对象,较完整地探测到矿区的沉降漏斗分布和沉降范围,为矿区的地表形变监测提供了可靠的技术支持。
In this paper,the SBASInSAR time series method is used to process the Sentinel1A data of 17 scenes from 2019/9/19 to 2020/3/29.The average annual subsidence rate in the northern coal mine area of Ji'ning city has been obtained,6 subsidence funnels have been detected,and the maximum subsidence rate can reach 242mm/y.It is showed that the SBASInSAR timeseries method can obtain enough monitoring objects in the monitoring of surface deformation in the mining area,and detect the distribution and settlement range of subsidence funnel completely.It will provide reliable technical support for the monitoring of surface deformation in the mining area.
