摘要
为研究霍林河北露天煤矿软岩边坡的蠕动变形演化规律,采用边坡雷达进行24 h不间断跟踪监测预警;介绍了真实孔径边坡雷达技术和临滑预警机制,并对监测案例进行了时间序列上的趋势分析。结果表明:边坡雷达可以实时掌握软岩边坡的动态变形情况,并对潜在的失稳边坡进行事前预警,最大限度地避免或减轻滑坡灾害造成的损失,保障露天矿的生产安全。
In order to study the creep deformation evolution law of soft rock slope in Huolinhe north open-pit coal mine,the article uses slope radar for 24 hours uninterrupted tracking monitoring and early warning,introduces the technology of real aperture slope radar and the early warning mechanism of impending slip,and analyzes the trend of monitoring cases in time series.The results show that:slope radar can grasp the dynamic deformation of soft rock slope in real time,and give early warning of potential unstable slopes,which avoid or mitigate losses caused by landslide disasters to the maximum extent,and ensure the production safety of open-pit mines.
