【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。更多还原

【Abstract】 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.更多还原
