岩石集中装药爆炸能量分布的计算

Distributions of explosion energy by concentrated Charge in rock

本文分析了岩石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~#岩石硝铵集中药包爆炸所消耗的爆炸气体膨胀能量、冲击波能量分别占装药总能量的50％～60％和10％～20％,无用能约占20％～30％。

In this paper, the procese of explosion break by aconcentrated charge in rock is analysecl and various energy distributions consumed during explosion are calculated.The result calculated shows that while the concentrated charge of 2 rock ammonium nitrate explosive explodes in rock. The shock wave energy consumed, the gaseous explosion products expansion energy consumed and useless energy, respectively, make up 50%～60%, 100%～20%,20%～30% of the total energy of the charge.
