然而、在实际爆轰条件下、热甲烷只要高于较低的可燃界限、一旦与大气的氧接触就会燃烧However, under actual detonation conditions the hot CH₄ is likely to combust on contact with atmospheric oxygen provided it is above the lower flammability limit
由于膨胀气体挤压这种物质、致使能量损失速度快、爆后产物的压力和温度迅速下降。这些损失作为膨胀波传到反应区之内、因而降低了压力和反应速率、且最终消除了对爆震波面传播的能量支持As the expanding gases compress such material, energy is lost rapidly and pressure and temperature drop sharply in the reaction products. These losses are communicated to the interior of the reaction zone as a rarefaction wave, lowering the pressure and reaction rate, and ultimately removing support far the propagation of the detonation front
通常在进行爆破方案设计时希望使抛掷量最大化。但是、在一些情况下并不需要达到最大抛掷量。例如当达到最大抛掷量会使得吊铲达不到最佳的工作高度时、反而造成爆后利润的降低Usually cast blast design involves maximizing the castover. However, in other situations less than maximum cast may be desired. This can occur far example if the after blast profile from maximum casting would lower the dragline elevation to the point where the machine has inadequate stacking height
通常说来、常温下含有很少液体或没有液体的多孔固体炸药、一般不受商业爆破中常见的低温的影响Typically, explosives that are porous solids at normal temperatures and contain little or no liquid are relatively unaffected at the normal low temperatures experienced in commercial blasting
