| Also, different gas concentrations result at different states of expansion,for example at the detonation state | 况且、气体的浓度不同、比如在爆轰态、会造成不同的膨胀状态 |
| Also, the explosives user would be wise to become aware of the variation in vibration sensitivities of different structures, utilities, facilities and materials, and to make note of the conditions near his operations | 此外、明智的炸药用户还须知道不同的结构、公用设施、设备和用具对振动感度的变化、而且要记录爆破场地附近的情况 |
| F-bursting can also occur when the front row has insufficient burden or drilling deviations from design | 当前排炮孔抵抗线不足或钻孔偏离了设计的方向时、也会发生自由面破裂现象 |
| For some types of blasting, it is also significant to consider the geometric shape and positioning of the explosive charges, sometimes called spatial distribution | 就某些类型的爆破而言、考虑药包的几何形状和安放位置、有时称之为空间分布、也有重要意义 |
| 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 | 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 |
| In the detonation of explosives, the resultant energy is converted into beneficial applications such as fragmentation and displacement. It is also responsible for adverse side effects such as vibration, airblast and flyrock | 在炸药爆炸过程中、合成能量转化为破岩和位移这些有益的实用能量。振动、冲击波和飞石这些不利的负面效应也是由合成能量产生的 |
| Our experiments also confirmed that the scatter of the angle of throw increases as the unloaded hole length decreases | 我们通过实验又证实、随着炮孔未装药部分的长度的减少、抛掷的散射角度则加大了 |
| Previous studies by many experts also show that flyrock can be avoided if the powder factor is smaller than a critical value。 | 很多专家以前的研究也表明、如果单位炸药消耗量小于临界值、飞石现象是可以避免的 |
| Such consideration also highlights the major targets for the blasting community to reduce GHG emissions through improved blast outcomes | 这些考虑的事项也突出表明、爆破界通过改进爆破结果来降低温室气体排放量是其主要目标 |
| 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 | 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 expansion work, however, also must include the energy of the energy released by afterburning | 然而、膨胀功也要包括二次燃烧时释放的能量效应 |
| Typical emission profiles from blasting and related downstream mining operations are also examined in this work | 典型的爆破气体释放剖面及相关下游采矿作业也在本文的研究之列 |
| 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 | 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 |
