摘要
露天矿山边坡稳定性控制对露天采场的安全生产起着至关重要的作用,而临近固定边坡的爆破效果又对边坡稳定性有着直接的影响。本文结合刚果(金)某露天铜钴矿的地质条件和施工特点,通过预裂爆破理论分析,并结合现场施工经验,总结了一套成熟的预裂爆破技术参数和施工方案。
The slope stability control of open-pit mine plays a vital role in the safe production of open-pit stope,and the blasting effect near the fixed slope has a direct impact on the slope stability.Combined with the geological conditions and construction characteristics of an open-pit copper cobalt mine in the Democratic Republic of the Congo,through the theoretical analysis of presplitting blasting and combined with the on-site construction experience,this paper summarizes a set of mature technical parameters and construction scheme of presplitting blasting.
