一组雷管的平均起爆时间一般稍微偏离标称的起爆时间。这种平均值对公称值的偏移则是第一个影响定时精确的因素。在平均值附近的起爆时间分布是第二个因素The mean or average firing time for any group of detonators typically is slightly offset from the nominal firing time. This shift of the mean from the nominal is the first timing accuracy factor. The distribution of the firing times around the mean firing time is the second factor

有人建议、用炸药里碳的总含量来作为确定爆炸时的温室气体排量的基础It is proposed that the total carbon content of the explosive should be used as the basis for GHG determinations from detonation
本文介绍将爆炸破碎粒度分布估计在 1 微米的方法、以便在各种岩石爆破时、对空气中有可能产生的可呼吸的浮尘作以定量比较This paper describes an approach to the estimation of blast fragmentation size distributions down to 1 micron so that quantitative comparisons can be made of the likely generation of air-borne, inhalable and respirable dust when different types of rock are blasted

火药系数与定时对岩石冲击破碎的影响effect of powder factor and timing on the impact breakage of rocks
然而、爆破所用炸药的特性、岩石类型或地质构造的物理特性或爆破定时起爆顺序及由于这些因素的微妙差别所产生的相互影响均要考虑There is no simple way, however, to take into account the interactions resulting from subtle differences in the characteristics of the explosives the blaster had at his disposal, the physical characteristics of specific rock types or geological formations, or the effect of the changes in timing of the initiation sequence on his blast
药包埋深不仅是决定空气压力强度的主要因素、而且对脉冲频率及持续时间也有影响The depth of burial of the charges is not only a primary factor in determining the intensity of the air pressures, but it also has an effect on the frequency and duration of the pulses
采矿时喷发的爆炸气体实际成分没法准确定论、这就是说、像甲烷这种有严重潜在危害的温室气体没法准确量化The actual make-up of detonation gases emitted on mines cannot be accurately determined and this means that potentially powerful GHGs like CH₄ cannot be quantified with any certainty
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
