摘　　要：定向爆破设计的核心内容是抛掷堆积计算,而抛掷堆积规律主要决定于布药结构。通过对通常采用的集中药包、条形药包和分集药包3种布药结构进行系统的爆破试验研究,以总结布药结构与抛掷堆积规律的关系,从而为定向爆破设计提供参考。Throwing accumulation is determined by layout of charge and the calculation of throwing accumulation is the kernel of directional blasting design. A series of experiments of the three kinds of layout of charge, concentrated charge ,linear charge,and sub-concentrated charge ,have been conducted to find the relationship of throwing accumulation and layout of charge. The results may serve as a reference to design of directional blasting.
