小直径炮孔一直采用浆状炸药、代那米特或低密度铵油炸药进行爆破。浆状爆药和代那米特比散装浆状炸药贵,而且有时装药困难。铵油炸药则因松堆密度低,常常不能足量地装入炮孔以达到破岩所需要的能极。可再泵送的乳胶浆状炸药是一种散装产品,可适用于直径2.5～6英寸的小孔。该产品装药效率高,爆破效果好,爆破成本低。 Small diameter blasthole has been using slurry explosives, dexrate or low density ammonium explosives for blasting. Slurry explosives and dexrate are more expensive than bulk sludges, and sometimes have difficulty loading. Ammonium oil explosives, however, are often not sufficiently loaded into the blasthole due to the low bulk density to reach the required energy for rock breaking. The pumpable latex syrup is a bulk product that can be used for small holes 2.5 to 6 inches in diameter. The product charge high efficiency, blasting effect, blasting low cost.
