当炸药威力大、产生的震感强、噪声大、飞石多。如果炸药威力太小、由于抵抗线和围压增加、会导致爆破失败、而且对于每次延时所用的药量而言、所产生的振动会比预计的要大While a high powder factor may generate higher levels of vibration, noise and flyrock, a power factor that is too low may cause a blast to fail and may generate more vibration than expected for the charge per delay that was used, because of increased burden and confinement
当量、当量的equivalent
然而、制造炸药使用生物燃料代替化石燃料的结果、会使二氧化碳的整体排量降低、因为生物燃料在生长期从大气中消除同样当量的二氧化碳However, the use of biofuels instead of fossil fuels in explosives would result in lower overall CO₂ emissions, as the biofuel growth phase removes an equivalent amount of CO₂ from the atmosphere
现代用的硝甘炸药可定义为雷管起爆型混合物。其中所含的硝化甘油敏化剂、或作为拓展能量的主要媒介、若适当起爆、雷管起爆型混合物则在爆轰速度下Modern dynamites can be defined a cap-sensitive mixtures which contain nitroglycerin as a sensitizer or as the principal means for developing energy, and which, when properly initiated, decompose at detonation velocity
调查结果表明、飞石事故是由以下一个以上的因素促成的: 地质及岩石结构的非连续性、炮孔布置和装药量不适当、抵抗线不足、炸药能量高度集中、填塞不足Investigations of flyrock accidents have revealed one or more of the following contributing factors: I discontinuity in the geology and rock structure,II improper blast hole layout and loading, III insufficient burden, IV very high explosive concentration, and V inadequate stemming
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
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
飞石产生的主要原因包括抵抗线不足、炮泥长度不够、钻孔不精确、单位炸药消耗量过多、地质条件不利露天节理、矿层不稳固和空穴、延时定时和序列不当、延时不精确、发生反向爆破、以及台阶上部岩石松散等The major causes of flyrock are inadequate burden, inadequate stemming length, drilling inaccuracy, excessive powder factor,unfavorable geological conditions open joints, weak seams and cavities, inappropriate delay timing and sequence, inaccuracy of delays, back break and loose rock on top of the bench
