很多实地操作人员把这种求导岩石系数的方法广泛应用于爆破剂破岩研究之中、并证明应用这种方法可以合理地估算所需的爆破强度以及诸多爆破环境下岩石的最终平均过筛粒度
This approach to the derivation of rock factors has been used by many field operators in a wide range of blasting and fragmentation studies and has been shown to lead to a reasonable estimate of the required blasting intensity and the resulting mean passing size in a wide range of blasting environments

、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
Our experiments also confirmed that the scatter of the angle of throw increases as the unloaded hole length decreases
