摘要
为了验证边坡雷达在露天矿山边坡变形监测预警中是否能够起到预警和警示作用,搜集边坡雷达在线监测预警系统在国内露天矿山采场运行中的一些典型应用案例,主要包括边坡出现裂缝变形、爆破震动变形、导水构造渗水变形、开采活动引起变形、台阶边坡围岩垮塌、连续降雨引起边坡局部垮塌等。通过对应用案例中边坡雷达监测数据的分析以及预警情况与实际情况进行对比,显示边坡雷达对直接作业活动引起的变形有明显的反应,并对非直接作业活动引起的变形起到的良好预警作用。边坡雷达对多种边坡破坏事件引起较大变形的成功预警,充分验证边坡雷达设备可以在露天矿山对采场边坡起到有效的预警作用。
In order to verify whether the slope radar can play an early warning role in the monitoring and early warning of the slope deformation of open-pit mines,some typical application cases of the slope radar online monitoring and early warning system in the stope operation of many open-pit mines in China are collected.Application cases mainly include crack deformation,blasting vibration deformation,seepage deformation of water conducting structure,deformation caused by excavation,collapse of surrounding rock of bench slope,local collapse of slope caused by continuous rainfall,etc.Through the analysis of the monitoring data of the slope radar in the application cases and the comparison between the early warning and the actual situation,the slope radar has an obvious response to the deformation caused by the direct mining operation,and a good early warning role played in the deformation caused by the indirect mining operation.The successful early warning of large deformation caused by various slope failure events by slope radar fully verifies that the slope radar equipment can play an effective role in early warning the stope slope in open-pit mines.
