用爆破法崩落岩石时,有件事很重要,即:保证矿岩必要破碎程度不是靠随着传爆速度的提高和释放能量时间的减少而增加的炸药威力,而是靠药包爆破的能量及其对岩石作用时间的增加。在这方面,探索扩大常规粒状炸药应用范围的可能性是很重要的,这种炸药可大大降低爆破落矿的费用,因为破碎功与能耗是成比例的。所以,结合被爆破岩体内炸药的合理分布而增加落矿炸药单位耗量的趋势是极其自然的。 When blasting a rock by blasting, it is important to ensure that the necessary crushing of the rock does not depend on the power of the explosive that increases with the increase of the blasting speed and the release of energy, but by the energy of the blasting of the pack And its role in rock time increases. In this regard, it is important to explore the possibility of expanding the range of applications of conventional granular explosives, which can significantly reduce the cost of blasting and demolishing, as the work of crushing is proportional to the energy consumption. Therefore, it is quite natural to combine the reasonable distribution of explosives in blasting rock mass to increase unit consumption of ore-blasting explosives.
