规格石爆破施工技术及实践

为解决采石工程中爆破产生的大量石粉不能满足石料粒径要求的问题,采用不耦合装药方式的规格石爆破技术,对降低石粉含量、提高石料的利用率效果显著。通过某采石工程的应用,结合低爆速炸药的应用,达到了减少弃料、降低开采投资成本的目的。

Regular Rock Blasting Technology and Practice

To avoid the quarry exploitation from too much rock powder dissatisfying with the aggregate size requirement,the regular rock blasting technology of decoupling charge can be adopted and it's greatly effective to minimize the powder quantity and enlarge the proportion of available aggregate.Combining the above technology with low detonation velocity explosive,the certain quarry project is realized with much less spoil and lower exploitation cost.
