基于D-InSAR的煤矿区开采沉陷遥感监测技术分析

该文在综合分析国内外开采沉陷监测技术现状、合成孔径雷达干涉测量(InSAR)和差分干涉测量(D-In SAR)技术发展及其在地表沉陷监测中应用成果的基础上,分析了D-InSAR技术在煤矿开采沉陷变形监测中的特点与技术优势。指出:应用D-InSAR进行煤矿区开采沉陷监测的具体目标是矿区地表沉降演变过程分析、采区地表沉陷动态监测与分析和矿区DEM数据更新;亟须研究解决的关键技术问题有:源数据获取与选择、数据处理方法、地面配合措施、精度与可靠性评价、多源信息集成分析等。D-InSAR为煤矿区地表时空演变过程研究和开采沉陷实时动态监测提供了新的技术方法;作为"数字矿山"的重要内容,D-InSAR可以有效地指导矿区生产、整体规划与长远发展,并为矿区可持续发展服务。

Technical Analysis of the Remote Sensing Monitoring for Coal-mining Subsidence Based on D-InSAR

Based on analysis of the present situation of the technologies in the mining subsidence monitoring,the developments of SAR interferometry (InSAR),differential InSAR(D-InSAR)and their applications in the surface subsidence monitoring,the features and advantages of D-InSAR applied in coal-mining subsidence monitoring are analyzed.It is also pointed out that the actual goals of D-InSAR monitoring for coal-mining subsidence include the process analysis of surface subsidence evolution in coal mines,the dynamic monitoring and analysis of surface subsidence in active mining zone and the DEM data update of coal mines.The key technologies that need to be solved include obtaining and selection of SAR data sources,methods for SAR data processing,ground assistant,data precision and reliability analysis and integral analysis on multi-source information.As an important part of Digital Mine,D-InSAR could be more effective in production guiding,mine planning and the sustainable development of coal mines.
