浆状炸药是一种钝感工业炸药,目前在冶金矿山得到广泛的应用,但是它需要用中继起爆药包起爆。国内外绝大多数矿山是使用铸装黑梯药柱。由于铸装工艺的特点,使药柱的结晶粗,缩孔多,造成药柱均匀性差,平均密度低,整个药柱爆压低,提供起爆能量低,生产中还会产生有害气体等缺点。为了改变这种状况,江西九三三三厂采用压装工艺(用一台300吨油压机)生产了WB304B起爆药柱,克服铸装药柱的缺点,而且经济更合理。这种药柱经在德兴铜矿使用效果很好,是金属露天矿较理想的起爆药柱。(一)浆状炸药的起爆原理炸药的起 Pulp explosives is an insensitive industrial explosive currently used in metallurgical mines for a wide range of applications, but it needs to be detonated with a relay detonator. The vast majority of mines at home and abroad are using cast black ladder medicine column. Due to the characteristics of the casting process, the coarse grains and shrinkage cavities of the medicine column cause poor uniformity of the medicine column, low average density, low explosion pressure of the whole medicine column, disadvantages of low initiation energy and harmful gas in production. In order to change this situation, JB 93,300 factory produced the WB304B detonating prod- ucts using a press-fit process (using a 300-ton hydraulic press) to overcome the shortcomings of the cast prills and to make the economy more reasonable. This kind of grain is used well in Dexing Copper Mine and it is the ideal priming material for metal open pit. (A) the principle of detonation of explosives explosives
