在分析了现有放炮装药方式的优缺点后提出了新的装药放炮工艺。此新工艺由两个相同大小的炸药卷(装在聚乙烯被筒中的ПЖВ-20号阿莫尼特炸药)组成。这两个炸药被筒用带轴的惰性间隔分开,在间隔上螺旋式缠绕起爆绳,它可以保证两筒炸药卷按计算的时间间隔延迟起爆(钻孔?
After analyzing the advantages and disadvantages of the existing gunning methods, a new gunning technology was proposed. The new process consisted of two explosive coils of the same size, a 12-gauge Armonite explosive packed in a polyethylene tube. The two explosives are separated by inertia of the spools with shafts and helically wrapped around the detonators at intervals to ensure that the two drum explosives are detonated at a calculated time delay (drilling?
