怎样提高爆破效率、改善爆破效果、增加进尺速度、保证巷道成型,仍然是岩巷掘进爆破工作中应解决的主要问题。从炮眼的深度、掏槽爆破、光面爆破、定向断裂控制爆破等技术问题进行分析研究,提出一些有益的参考。
How to improve blasting efficiency, improve blasting effect, increase footageing speed and ensure laneway forming are still the main problems that should be solved in tunneling and blasting work. From the depth of the blasthole, cut blasting, smooth blasting, directional rupture control blasting and other technical problems analysis and research, put forward some useful references.
