摘　　要：本文讨论了条形空腔药包的破坏范围和抛掷、堆积规律,以及多层多排布药方案分段起爆时,后排药包临空面及最小抵抗线的确定方法。The failure zone and ejecta crest produced by space-charges explosion in long cavity column are discussed in this paper. The methods for determing the free surface of the rear-row spaced-charges and the least-resistance line, under the condition of multi-layer and-row spaced-charges scheme with progressively discrete explosion, are also given.
