chemical gassing to control product density and sensitivity when loading wet holes is now common in the industry
给湿孔装药时,用以控制炸药密度和感度的化学气泡法是爆破作业一种常见的方法
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

Investigations of flyrock accidents have revealed one or more of the following contributing factors:
I
discontinuity in the geology and rock structure,
II
improper blast hole layout and loading,
III
insufficient burden,
IV
very high explosive concentration, and
V
inadequate stemming
调查结果表明、飞石事故是由以下一个以上的因素促成的: 地质及岩石结构的非连续性、炮孔布置和装药量不适当、抵抗线不足、炸药能量高度集中、填塞不足
It is discovered in filed experiments that most of the collar flyrock is thrown in a direction fallowing the drill hole axis
现场实验发现、孔口周围的大部分飞石沿着炮孔轴线方向抛掷出去

孔内延时起爆药是放在炮孔内与导火索用在一起的起爆装置、以起爆各层非雷管起爆炸药
The gas composition is strongly dependent on many factors such as actual field detonation conditions, rock type,hole diameter,water presence,product homogeneity
in the hole
气体的形成在很大程度上取决于诸多因素、如现场实际爆轰条件、岩石类型、炮孔直径、有没有水以及炸药在炮孔中是否均匀等
