摘要
为了保障露天矿区安全生产及运营,针对露天矿区形变区难以及时识别与监测问题,采用星载合成孔径雷达干涉测量(InSAR)和地基InSAR联合监测模式,对露天矿区开展不同阶段、多尺度的形变区域识别与监测,分析形变趋势,研究二者InSAR技术在露天矿区形变区调查、重点形变区确定及监测预警的应用效能。研究结果表明:星载InSAR技术实现对露天矿区的广域地表形变监测,且识别出重点形变区,分析形变发展趋势;地基InSAR实现了对露天矿区重点边坡形变区进行近实时、高频率的监测,根据监测数据变化趋势,判别形变发展阶段;两者InSAR技术结合应用,充分发挥各自优势,星载InSAR实现面域形变区识别与监测,地基InSAR实现重点形变区的高频监测及无法形成有效干涉形变区的补充监测,获取了更为详细、全面的形变信息,为露天矿区形变灾害监测预警提供高效、可靠的监测数据,提升露天矿区防灾减灾的能力。
In order to ensure the safe production and operation of the open-pit mining area,it is difficult to identify and monitor the deformation area of the open-pit mining area in time,the joint monitoring mode of satellite interferometric synthetic aperture radar(InSAR)and ground-based InSAR were applied to carry out different stages,multi-scale deformation area identification and deformation trend analysis in open-pit mining areas.The application efficiency of the two InSAR technologies in the investigation of deformation areas in open-pit mines,determination of key deformation areas,and monitoring and early warning was studied.The research results showed that the satellite InSAR technology could realize the wide-area surface deformation monitoring of the open-pit mining area,and identify the key deformation areas,analyze the deformation development trend;The ground-based InSAR technology can realize real-time and high-frequency monitoring of key slope deformation areas in open-pit mining areas,and determine the deformation development stage according to the change trend of monitoring data;The combined application of the two InSAR technologies gives full play to their respective advantages.The Satellite InSAR could be applied to realize identification and monitoring of area deformation areas,and the ground-based InSAR realizes high-frequency monitoring of key deformation areas and supplementary monitoring of deformation areas that couldn’t form effective interference,obtained more detailed and comprehensive deformation information,provided efficient and reliable monitoring data for the monitoring and early warning of deformation disasters in open-pit mining areas,and improved the ability of open-pit mining areas to prevent and reduce disasters.
