摘要
如何提高爆破效率、改善爆破效果、增加进尺、保证成型,仍是岩巷掘进爆破工作中应解决的主要课题。文章对炮眼深度、掏槽爆破、光面爆破、定向爆破等技术问题进行了探讨。
How to raise blasting efficiency, improve blasting effect, increase drifting footage and ensure forming is a main problem that should be resolved in the blasting working of stone drifting. The technology problems of blasthole depth, cutting blasting, smooth wall blasting, and directional blasting is discussed.
