破碎岩体条件下露天铅锌矿预裂爆破对边坡稳定性影响研究
Research on the Impact of Presplit Blasting on Slope Stability in Open-Pit Lead-Zinc Mines under the Condition of Fractured Rock Mass
摘要
Abstract
Taking a certain open-pit mine in western Yunnan as the research object,which features complex geological conditions,well-developed joint fissures in the rock mass,and multiple lithologies within the same blasting area,this study investigates the impacts of conventional blasting and presplit blasting on slope failure.The results indicate that:By adjusting blasting parameters according to rock properties in areas with multiple lithologies,the blasting effect in the main blasting zone is remarkable,with a block rate of 4.19％,though the slope surface is relatively fragmented.The adoption of presplit blasting technology results in a smooth and intact slope surface,providing a reference for similar mining operations.关键词
