摘要
以冀东地区某铁矿露天采场西帮边坡滑坡体为研究对象,通过展开土力学试验和边坡反演模拟分析,得出该区域边坡为土质边坡,富水性强,滑坡模式为近似圆弧型边坡失稳。根据不同区域的边坡稳定现状,采取西帮边坡削坡放缓、分区加固和疏干排水措施,治理后的N8~N16边坡安全稳定系数达到1.2以上,满足《非煤露天矿边坡工程技术》(GB51016-2014)要求,有效解决西帮边坡滑坡问题,为矿山安全高效生产提供可靠的保障。
Taking the landslide body of the west slope of an iron ore open-pit stope in eastern Hebei region as the research object,the soil mechanics tests and slope inversion modeling analysis are carried out,and it’s obtained that the slope in this area is a soil slope with strong water richness,and the landslide pattern is approximately circular slope instability.According to the current situation of slope stability in different regions,measures such as slope cutting and slowing down,zoned reinforcement,and dewatering and drainage are taken for the west slope and the safety and stability coefficient of the N8 to N16 slopes after treatment reaches more than 1.2,which meets the requirements of the"Technical Code for Non-coal Open-pit Mine Slope Engineering(GB51016-2014)",effectively solves the landslide problem of the west slope,and provides a reliable guarantee for the safe and efficient production of the mine.
