使变得不拘束thaw
这些颗粒溶解后、多孔颗粒中封闭的空气得以释放、且不再有使炸药敏化的效力。此外、溶解后的硝铵与水一起处于液态、在爆轰时不再具有起反应的效力When the prills dissolve, the air entrapped inside the porous prills is released and is no longer available to sensitize the composition. Also, the dissolved ammonium nitrate stays in solution with water and is no longer available to react in the detonation
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
通过测量得知、由于温室气体的排放、大气二氧化碳浓度正在不容置疑地逐年加速增加The measured atmospheric concentrations of carbon dioxide show an inexorable and accelerating year-on-year increase arising from greenhouse gases emissions
钻孔控制得当一则能减少不合格的炮孔、二则有可能减少每个炮孔的装药量Good drilling control also helps to reduce the subgrade drilling and may make it possible to make some reduction in the total charge per hole
