关于降低露天采场爆破大块率的实践探讨

Practical Discussions on Reducing Big Rock Rate of Blasting in Open Pit

台阶深孔爆破是露天矿山开采的主要手段,爆破质量的好坏直接影响后续采装工艺以及整个生产工艺能否顺利完成,对产量的完成以及资本的消耗都有至关重要的作用。本文结合白云铁矿东采场的生产实际情况,探讨降低爆破大块的方法,为公司降本增效献计献策。

The bench deep - hole blasting is the main measure for open - pit mining. The blasting quality directly in-fluences whether the subsequent mining, loading and the whole production technologies could be smooth, which is vital for completing the production and capital consumption. In the paper, the methods for reducing big rocks of blasting are dis-cussed combining with the actual situations of productions in the East Stope of Baiyunebo Iron Mine to contribute ideas andexert efforts for reducing costs and increasing benefits.
