导爆管起爆系统是一种新的起爆技术,它适用于无瓦斯矿尘爆炸危险的露天、井下矿山及其他场所的爆破作业。使用这种非电起爆系统必须根据使用地点的地质条件,采用合理的爆破参数,才能得到满意的效果,如果盲目从事就会弄巧成拙。例如我矿1981年采购了一批带半秒差雷管的导爆管,在巷道掘进试用过程中,出现过下列现象:(1)爆下岩石拋掷太
Detonating tube detonation system is a new detonation technology, which is suitable for blasting operations in the open air, underground mines and other places without the danger of gas and dust explosion. Use of such non-electric detonation system must be based on the geological conditions of the use of the site, the use of reasonable blasting parameters in order to get satisfactory results, if blindly engaged in self-defeating. For example, in 1981, I Mine purchased a number of detonators with semi-second differential detonators. During the tunneling trial, the following phenomena occurred: (1)
