摘要
针对常规矿区地表沉陷监测方法的缺点,基于D-InSAR技术,对2016年12月18日—2017年2月25日的两景RADARSAT-2雷达数据进行差分干涉处理,获取了研究区域监测时间段内的开采沉陷信息,监测到3处沉陷盆地分布,结合实际情况,对监测结果和精度进行了分析。结果表明,D-InSAR技术能够有效监测矿区的地表沉陷分布及特征,可为研究大范围矿区的地表沉陷动态监测提供技术参考。
In view of the shortcomings of conventional mining area surface subsidence monitoring methods,based on D-InSAR technology,differential interference processing has been carried out on RDARSAT-2 radar data of two scenes from December 18,2016 to February 25,2017.Mining subsidence information within the monitoring period in the study area has been obtained,and three subsidence basins have been monitored.Combining with actual situation,the monitoring results and accuracy have been analyzed.It is showed that D-InSAR technology can effectively monitor the distribution and characteristics of surface subsidence in mining areas,and can provide technical references for studying dynamic monitoring of surface subsidence in large mining areas.
