摘要
本文就提高炮眼利用率、加快掘进速度问题从炮眼布置、炮眼深度、装药结构、凿岩工艺等方面进行综合探讨。研究表明,合理布置炮眼、加大炮眼深度、运用不同阶微差爆破技术是获得良好爆破效果和提高掘进速度的关键。
In this paper,the problem of increasing the utilization rate of cannon hole and speeding up the excavation speed is discussed comprehensively from the aspects of cannon hole arrangement,hole depth,charge structure,rock drilling technology and so on. The results show that it is the key to obtain good blasting effect and improve excavation speed to arrange the cannon hole reasonably,increase the depth of the cannon hole and use different order differential blasting technology.
