摘要
为了优化现有的中深孔凿岩爆破参数,通过系列爆破漏斗试验,为采矿设计提供合理的炸药单耗、最小抵抗线和最大孔底距参数范围,从而改善爆破效果,降低采矿成本。
To optimize the existing blasting parameters of medium-length hole drilling,a series of blasting funnel tests are carried out to provide reasonable parameters of unit wastage of explosive,the least resist distance and the most hole-bottom distance for mining design so as to improve the blasting effect and reduce mining cost.
