半煤岩巷快速掘进爆破参数优化研究

摘要

This paper calculated the blasting parameters in tunnel tunnelling from holes number and holes depth two aspects,and gave the pa-rameter calculation methods of cut holes,aided holes,designed the layout situation and its charging structure of various blasting holes,for refer-ence.%从炮眼数目选择与炮眼深度两方面对在巷道掘进中的爆破参数进行了计算，并给出了掏槽眼、辅助眼的参数计算方法，设计了各种爆破眼的布置情况和其装药结构，以供参考。
