采矿工业是国民经济中主要工业基础之一,在坚硬岩石的条件下,利用钻眼爆破乃是采掘矿石的主要工艺过程之一,而钻眼爆破工作中,所用炸药的威力大小以及是否安全、经济,将对整个掘进或矿石单位成本与效率起着很大作用,因为硝铵炸药在使用上既安全又经济,在我国以及其它社会主义国家中在采矿建筑等工作中,广泛使用着硝铵炸药。但与消化甘油炸药相比,亦有缺点,即其威力小,装药密度低,所需钻眼工作量大,例如硝化甘油炸
Mining industry is one of the major industrial bases in the national economy. Under the conditions of hard rock, the use of drilling and blasting is one of the main processes for mining ore. In drilling and blasting, the power and explosiveness of explosives are safe, Economy, will play a significant role in the cost and efficiency of the entire tunneling or ore unit. Because ammonium nitrate explosives are both safe and economical to use, ammonium nitrate is widely used in mining and construction work in our country and other socialist countries. Explosives. However, compared with the digestion of glycerin explosives, there are disadvantages that its power is low, the charge density is low, the drilling effort required for large, such as nitroglycerin fried
