BJ-2炸药是一种组分搭配合理、并加有特种添加剂的高密度抗水乳化炸药。该炸药抗水性强,不污染环境,且比普通乳化炸药成本低10～15％,比CLH系列三高炸药低50％。其密度为1.18～1.30克/厘米~3,爆速4000～4500米/秒。经试验,在1.2米深水中浸泡60小时,爆速仍为4093米/秒。殉爆度为80～100毫米,猛度12～20毫米。该炸药不仅适合于大直径有水深孔,而且也适合于地下矿山中 BJ-2 explosives is a component with a reasonable, and add special additives, high-density water-resistant emulsion explosives. The explosives are water-resistant and do not pollute the environment. They cost 10-15% less than ordinary emulsion explosives and are 50% lower than CLH series three-high explosives. The density of 1.18 ~ 1.30 g / cm ~ 3, detonation velocity 4000 ~ 4500 m / s. After testing, deep soaking in 1.2 meters for 60 hours, the detonation velocity is still 4093 m / s. Martyrs burst degree of 80 to 100 mm, 12 to 20 mm fierce degree. The explosive is not only suitable for large diameter water deep hole, but also suitable for underground mines
