    Monitoring and early-warning of surface deformation in mine goaf based on InSAR

    • 摘要: 以近期发生采空区矿震的山东某煤矿为研究区,利用DInSAR、SBAS InSAR技术对矿震发生前后、覆盖该矿区的11景C波段Sentinel-1A SAR影像进行处理,获取矿震发生前后的地表形变信息,分析并研究这2种InSAR技术对采空区地表形变的监测能力和矿震预警能力。结果表明:在矿震发生前的1个月左右,2种InSAR技术均探测到矿区地表形变出现异常,由较为平稳的形变过程变成明显下沉,利用DInSAR和SBAS InSAR可以探测煤矿采空区长时间的地表形变过程和形变异常,为矿区采空区地表稳定性分析和矿震预警提供参考。

       

      Abstract: To study the monitoring and early warning ability of DInSAR and SBAS InSAR for mine earthquake collapse in goaf area, this paper uses the two InSAR techniques to process the 11 scene C-band Sentinel-1A SAR images before and after the mine earthquake to obtain the mine deformation by taking the coal mine in Shandong Province where mine earthquake recently occurred in goaf area as the research area. The result shows that both InSAR technologies detected abnormal surface deformation in the mining area, which converted from relatively stable deformation process to obvious subsidence. DInSAR and SBAS InSAR can be used to detect long-term surface deformation process and abnormal deformation in the goaf, and provide a reference for the analysis of the surface stability of the goaf area and early warning of mine earthquakes.
