SBAS-InSAR技术支持下的矿山地表形变监测研究

Research on Surface Deformation Monitoring of Suburban Coal Mines Supported by SBAS⁃InSAR Technology

利用SBAS⁃InSAR技术对矿山地表形变进行全面监测。以河南永城矿区为研究对象,深入研究了该地区的地质情况及可能的地表变化类型,并设计了监测方案。介绍了如何获取和处理合成孔径雷达(SAR)数据,以及干涉图生成的关键步骤。通过分析时间序列形变图和形变结果,揭示了矿区地表形变的趋势。该研究有助于解决河南永城矿区地表形变的问题,为地表形变监测领域提供了一个重要范例,有望更好地理解煤矿地表的演化过程,为降低地质灾害风险及矿山的安全运营提供了关键支持。

This study aims to use SBAS⁃InSAR technology to comprehensively monitor the surface deformation of coal mines in urban suburbs.Taking the Yongcheng coal mine area in Henan Province as the research object,this study conducted in⁃depth research on the geological conditions,possible types of surface changes,and the design of monitoring plans in the area.Introduced how to obtain and process synthetic aperture radar(SAR)data,as well as the key steps in generating interferograms.By analyzing the time series deformation map and deformation results,the trend of surface deformation in the mining area was revealed.This study helps to solve the problem of surface deformation in the Yongcheng mining area of Henan Province,providing an important example for the field of surface deformation monitoring.It is expected to better understand the evolution process of coal mine surface in the suburbs of the city,reduce geological disaster risks,and provide key support for the safe operation of mines.
