动能消耗率 | rate of dissipation kinetic energy |
单位炸药消耗量爆破单位体积原岩〈煤〉消耗的炸药质量 | explosive factor |
单位炸药消耗量破每立方米或每吨矿岩的炸药消耗量〈计划或实际耗量〉,单位为 kg/m³ 或 kg/t | specific charge |
单位炸药消耗量爆破单位体积原岩〈煤〉消耗的炸药质量 | specific charge |
单位炸药消耗量爆破单位体积原岩〈煤〉消耗的炸药质量 | powder factor |
在爆破中产生飞石所消耗的能量低于传递给岩石全部能量的1%、因此以这种形式浪费的爆炸能可以说微不足道 | The energy spent in creating flyrock during blasting is less than 1 % of the total energy transferred to the rock, hence the wastage of explosive energy in this form maybe insignificant |
在爆破设计时选择最佳单位炸药消耗量,既能消除经济成本方面的顾虑,又能消除环境方面的顾虑 | An optimum powder factor can satisfy both economic and environmental considerations in blast design |
大多数民用炸药在爆炸时、只有部分在爆轰波阵面起反应、尚有很大一部分在膨胀阶段进行二次燃烧时才消耗掉 | In most commercial explosives, only part of the ingredients react immediately at the detonation front, leaving a considerable part to be consumed by aftercombustion during the expansion phase |
大多数民用炸药在爆炸时、只有部分在爆轰波阵面起反应、尚有很大一部分在膨胀阶段进行二次燃烧时才消耗掉 | In most commercial explosives, only part of the ingredients react immediately at the detonation front, leaving a considerable part to be consumed by afterburning during the expansion phase |
年消耗定额计算 | annual consumption norm calculation |
年消耗量 | yearly consumption |
年度消耗量 | annual consumption |
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 | Previous studies by many experts also show that flyrock can be avoided if the powder factor is smaller than a critical value。 |
改进后抛掷爆破法可减少大煤矿的电力消耗、且不需要索斗铲进行大量的剥离运动 | Electricity consumption on large coal mines may be reduced through improved throw blasting, requiring less overburden movement by the draglines |
炸药消耗总量用于具体任务的炸药总量 | explosive consumption total |
炸药消耗指标 | indicator of explosives consumption |
炸药消耗比 | explosive ratio |
炸药与岩体的关系被认为是单位炸药消耗量、爆破人员可用来作为确定岩体中炸药分布的总指标 | The relationship between the explosive and the rock mass is known as the powder factor and can be used by the blaster as a general guideline for determining explosive distribution in the rock mass |
然而、大规模减少单位炸药消耗量是不可取的、因为这样反倒影响破碎作用和排石量 | It is not recommended, however, to reduce the powder factor significantly because it will adversely affect the fragmentation and |
燃烧比耗、燃料消耗率 | specific fuel consumption |
爆破单位岩石体积的炸药消耗量 | explosive ratio |
能源消耗模式 | energy consumption pattern |
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 |
