浆状炸药以其适应有水炮孔的特性而在露天矿山得到迅速发展。据统计,全国12个冶金露天矿每年浆状炸药用量在两万吨以上,约占整个矿用炸药总量的20％。然而,现有的装药技术却不能满足炸药发展的需要,长期以来采用人工袋装方式,装药效率低且质量差。因此,实现装药机械化已成为矿山生产的迫切需要。 Pulp explosives in its adaptation to the characteristics of water holes in the open mines have been rapidly developed. According to statistics, the amount of slurry explosives used in each of the 12 open-pit mines in the country is more than 20,000 tons, accounting for about 20% of the total amount of mining explosives. However, the existing charge technology can not meet the needs of the development of explosives. For a long time, manual bagging has been adopted, which is inefficient and of poor quality. Therefore, the mechanization of charging has become an urgent need for mine production.
