| effect of powder factor and timing on the impact breakage of rocks | 火药系数与定时对岩石冲击破碎的影响 |
| factor of safety | 安全系数为保证斜坡稳定而采用的具有一定安全储备的稳定性系数 |
| factor of stability | 稳定性系数滑动面上抗滑力〈或力矩〉与滑动力〈或力矩〉的比值 |
| factor of the stress concentration | 应力集中系数 |
| In the presence of multicollinearity,redundancy of the independent variables exists, which can lead to erroneous effects by the independent variables on the dependent variable. The existence of multicollinearity can be checked from a calculation of the variance inflation factor VIF of the independent variables | 在有多重共线性的情况下、就会出现多余的自变量、这样会使自变量对应变量产生错误影响。多重共线性是否存在、可以通过对自变量的方差膨胀因子的计算来检验 |
| initial factor of safety | 初期安全系数 |
| softening factor of rock | 岩石软化系数岩石水饱和试件与干燥试件的单向抗压强度之比值 |
| 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 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 | 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 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 | 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 |
| utilization factor of construction equipment | 施工机械利用率施工机械实际台班数与制度台班数的比值 |
| weakness factor of rock strength | 岩石强度弱化系数饱水状态下岩石的抗压强度与干燥状态下的抗压强度之比 |
| 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 |
