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。
Based on the comprehensive analysis of the status quo of mining subsidence monitoring technology at home and abroad, the development of InSAR and D-In SAR technology and its application in the monitoring of surface subsidence, Features and Technical Advantages of InSAR Technology in Deformation Monitoring of Coal Mining Subsidence. It is pointed out that the specific targets of D-InSAR mining subsidence monitoring are the analysis of surface subsidence evolution process, the dynamic monitoring and analysis of surface subsidence in mining area and the renewal of DEM data in mining area. The key technical problems urgently needed to be solved include: source data acquisition And selection, data processing methods, ground coordination measures, accuracy and reliability evaluation, multi-source information integration analysis. D-InSAR provides a new technical method for studying the temporal and spatial evolution of the surface of coal mines and real-time dynamic monitoring of subsidence. As an important part of Digital Mines, D-InSAR can effectively guide the production, overall planning and long-term development of the mines , And for the sustainable development of mining services.
