乳化粒状炸药是一种基于粒状硝铵和乳胶体的新型炸药,配合装药器在地下矿山生产爆破中可实现压气机械装药。我矿于1989年在北京矿冶研究总院协助下,将这种新型炸药使用于井下中深孔压气装药爆破,效果良好。它与粉状硝铵炸药比较,一是成本低,二是反弹率低。如,在我矿乳化粒状炸药生产成本为700(元/吨)左右,而外购2号岩石硝铁炸药2100(元/吨),仅为外购炸药价格的三分之采用乳化粒状炸药后,中深孔爆破实现了装药机械化,装药效率高,与人工普通法装药比较,工人的劳动强度大大降低,作业环境改善,人员减少,节约了硐室内搭台的辅助作业时间及原材料,
Emulsion granular explosives is a new type of explosives based on granular ammonium nitrate and latex, which can be applied to the pneumatic mechanical charge in the blasting of underground mines with the chargers. I mine in 1989 with the assistance of Beijing Mining and Metallurgical Research Institute, the use of this new type of explosives deep hole in the underground gas charge blasting, the effect is good. It is compared with powdered ammonium nitrate explosives, one is low cost, the second is the rebound rate is low. For example, the cost of producing mineral emulsified granular explosives is about 700 yuan (RMB / tonne), while the purchased No. 2 rock nitric oxide explosive 2100 (yuan / ton) is only one-third of the price of the purchased explosives after using emulsified granular explosives , Medium-deep borehole blasting realized the charge mechanization and high loading efficiency. Compared with the artificial common law charge, the labor intensity of the workers was greatly reduced, the working environment was improved, the personnel was reduced, the auxiliary work time and the raw materials ,
