微变监测雷达在扎哈淖尔露天煤矿的应用

Application of micro-variation monitoring radar in Zhahanao'er Open-pit Mine

为实现扎哈淖尔露天矿边坡工程的稳定性监测及临滑预警,基于合成孔径雷达(SAR)/真实孔径雷达(RSR)和差分干涉雷达(DInSAR)的技术,应用在地基轨道上形成微变监测雷达,采用微变监测雷达对观测场景(地质隐患点、露天矿山边坡等地质体)进行地表微小形变数据信息的提取,获取雷达监测区域位移及速度数据。结果表明:微变监测雷达可获取边坡形变数据,并分析出所处的变形阶段,为后续的采掘设计和排土方案等提供技术保障。

In order to realize stability monitoring and impending slip warning of Zhahanao’er open-pit Mine slope engineering,based on the technologies of synthetic aperture radar(SAR)/real aperture radar(RSR)and differential interference radar(DInSAR),the article uses micro-variation monitoring radar to form the micro-variation monitoring radar on the ground track,and adopts the micro-variation monitoring radar to extract the data information of the surface micro-deformation of the observation scene(geological hidden danger point,open-pit mine slope and other geological bodies),so as to obtain displacement and velocity data of radar monitoring area.The results show that the micro-variation monitoring radar can obtain the deformation data of slope and analyze the deformation stage,which provides technical support for subsequent mining design and soil discharge scheme.
