摘　　要：文中分析了岩石中集中装药爆炸破坏过程，计算了爆破过程所消耗的各种能量的分布。计算结果表明：岩石中２＃岩石铵梯炸药集吕药包爆炸时所产生的爆炸气体膨胀能量，冲击波能量分别占装药能量５０％－６０％和１０％－２０％，无用能约占２０％－３０％。The process of explosion break by a concentrated charge in rock blasting is analyzed and the distribution of various energy consumed during explosion is also calculated. It shows that, in rock blasting, the expansion energy of gaseous explosion product, shock wave energy and useless energy are ranged from 50%～60%, 10%～20%, and 20%～30% respectively in the proportion of the total energy.

关 键 词：集中装药 爆炸气体膨胀能量 冲击波能量
