聚能药包重0.025—1公斤,可用于露天或坑内矿破碎不合格的大块矿岩。这些药包的特点是:都具有金属端板,以使爆炸能集中作用到矿岩上,并可延长其作用时间;采用的炸药密度大(1.5—1.6克/厘米~3)、爆速高(7000—7500米/秒)。工业试验证明,采用这种聚能药包和普通药包相比,炸药消耗降低75—86%,二次破碎费用减少30—50%,二次破碎爆破工劳动生产率提高1—2倍,二次破碎可在设备附近进行,爆破产生的矿尘和炮烟均可减少。
Poly energy medicine package weighing 0.025-1 kg, can be used in open pit or mine failure unqualified large ore rock. These kits are characterized by having metal end plates to concentrate the blast energy on the ore rock and to extend its action time; explosives are used at high densities (1.5-1.6 g / cm3) and high detonation speeds (7000 -7500 m / s). Industrial tests show that, compared with ordinary drug packs, the energy accumulator pack reduces the explosive consumption by 75-86%, the secondary crushing cost by 30-50%, the secondary crushing and blasting worker’s labor productivity by 1-2 times, and the second Sub-crushing can be carried out in the vicinity of the equipment, mine dust and cannon smoke generated by blasting can be reduced.
