摘要
该文将针对岩石硬度较大,采取钻爆法掘进的半煤岩巷道分次爆破的爆破方法进行探索研究,在保证施工安全的同时,确保巷道成型规格,提高了爆破效率。
This article will focus on rock hardness is larger, to drilling and blasting method of tunneling by several times of half coal rock tunnel excavation blasting blasting method, while ensure construction safety, ensure the roadway tunnel molding spec at the same time, improve the blasting stubble.
