我国第一座年产千吨级的乳化炸药工厂——龙烟铁矿201厂,从1981年3月投产以来,设备运转正常、产品质量稳定,各项性能均达到或超过鉴定会上确定的指标。工业生产的EL系列乳化炸药在普通库房内存放六个月后,爆速仍保持在4000(米/秒)以上,殉爆距离80毫米以上。此炸药除用在龙烟铁矿生产之外,还支援了兄弟矿山及有关工程。铁道兵某部在天津“引滦入津”工程中承担凿通10余公里长的隧道任务。该部队在施工中,原使用2号岩石硝铵炸药,由于不抗水、瞎炮多,炮孔
China’s first annual output of 1,000 tons of explosives explosives factory - Longyan Iron Ore 201 plant, put into operation from March 1981, the equipment is operating normally, the product quality is stable, the performance met or exceeded the identification meeting identified index. Industrial production of EL series of emulsion explosives stored in the ordinary warehouse six months after the detonation rate remained above 4000 (m / s), detonation distance of 80 mm or more. In addition to the use of explosives in Longyan iron ore production, but also support the brothers mine and related projects. A section of the railway corps undertakes the task of tunneling more than 10 kilometers long in the “Luan River to Tianjin” project in Tianjin. The force in the construction, the original use of No. 2 rock ammonium nitrate explosives, due to no resistance to water, blind cannons and more holes
