基于InSAR技术在煤矿采空区地表形变的应用分析OA
Application Analysis on Surface Deformation of Coal Mine Goaf Based on InSAR Technology
为及时、精准监测矿区地表沉陷情况,基于 SBAS-InSAR时序分析技术,利用 20201031-20210429和20211107-20220506两个时段的 18景 Sentinel-1A影像,通过 InSAR时序技术对数据进行了处理,研究获取了菏泽市南水北调调蓄及供水保障工程赵楼节制闸区域的垂直变形累积形变特征.目标区域赵楼节制闸周边500 m范围内的累计沉降量介于-20～10 mm之间,节制闸所处位置的地表累计沉降量分别处于-7～8 mm和-16～-3 mm之间.该数据为该区域采空区地基稳定性评价提供了可靠的数据支撑.
In order to timely and accurately monitor the surface subsidence situations of mining areas,based on SBAS-InSAR time series analysis technology,18 scenes Sentinel-1A images from the two periods of 20201031-20210429 and 20211107-20220506 are utilized to process the data through InSAR time series technology.The vertical deformation accumulated deformation characteristics of of South to North Water Diversion and Storage in Heze City and Water Supply Guarantee Project in Zhaolou check-gate area are obtained by the research.The accumulated subsidence volume within a range of 500 m around the Zhaolou check-gate in the target area is between-20 mm and 10 mm,and the surface accumulated subsidence volume at the location of the check-gate is between-7 mm-8 mm and-16 mm--3 mm,respectively.This data provides reliable data support for the stability evaluation of the goaf foundation in this area.
