冲击波压力损失与炸药的爆炸压力有关、可以通过计算炸药的密度和爆速来估算。因此、炸药的冲击波压力损失的测定可以通过实验引人一些诸如温度、静态和动态预压及导爆索支线等变量来确定
The shock pressure loss is related to the explosive's detonation prepressure, which can be estimated by knowing the density and detonation velocity of the explosive. Therefore, the SLF for a test explosive can be experimentally determined by introducing in the test certain additional variables, such as temperature,static and dynamic pre-compression and detonating cord downline
对所预测的碎岩粒度分布的粗端往往给以过高估计、这是因为碎岩最大粒度不受模型中岩体结构的影响
The coarse end of the predicted fragmentation size distribution is often over-estimated because the fragment top size is not influenced by the structure of the rock mass in the model
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
爆破人员务必要估计出飞石自爆炸点可能行走的最大距离
A blaster must make an estimate of the maximum possible distance flyrock could travel from a shot
该评估与岩石含水量规定的值密切相关、而与实际爆破设计方案或实施的爆破强度无关
These estimates are very sensitive to the value used for the moisture content of the rock and are quite independent of the actual blast design or blasting intensity applied
