摘要
基于矿山复杂地质边坡及前期爆破经验与效果,特对该边坡采取预裂穿孔、不耦合装药、逐孔起爆等手段,实现矿山安全生产。
Based on the complex geological slope and the experience and effect of blasting in the early stage,the measures such as presplitting and perforating,uncoupled charging and hole by hole initiation are adopted to realize the safe production of the mine.
