随着我国国民經济的飞跃发展,許多規模巨大的矿山、水利、鉄路开采剝离工程,愈来愈多的采用了大规模的爆破作业,因而,炸藥的消耗急剧增加。炸藥費用在其总費用中的比重很大,以我矿的露天开采来看:采掘單位矿石的直接生产成本中炸藥费用佔55～60％,剝离的直接成本中炸藥費佔45～50％。因此寻求一种既便宜而又具有相当威力的炸藥来代替現时 With the rapid development of our national economy, many large-scale mining, water conservancy, and Kushiro mining stripping projects have increasingly adopted large-scale blasting operations and the consumption of explosives has dramatically increased. Explosive charges in the total cost of a large proportion of mine to open-pit mining point of view: mining unit ore direct production costs of explosives accounted for 55 to 60%, stripping the direct costs of explosives accounted for 45 to 50% . So instead of looking for a cheap and quite powerful dynamite instead
