摘要
用空气、水和岩粉３种间隔材料进行了间隔装药爆破试验，研究了间隔对破碎块度的影响，得出３种材料的临界间隔比例值，对比了该３种材料间隔与全长偶合装药的异同，讨论了间隔的位置、长度及间隔材料对爆破破碎效果的影响。
Using water, air and rock powder as interval materval materials, the explosive experiment of interval charge is made. Interval effect on broken block degree is researched. The difference of interval charge of three materials and coincidental charge is discussed. Influence of position, length and materials on rock broken effect are analysed.
