摘要
介绍了区段石门掘进中影响爆破质量的主要因素,结合福建某煤矿区段石门掘进中光面爆破的具体方案,总结了类似巷道掘进中如何合理确定爆破参数,实施爆破方案,从而有效控制巷道轮廓,并提高掘进速度。
This paper introduces the main factors that affect the quality of blasting in cross-cut excavation and draws a conclusion about how to fix blasting parameters in similar tunnel excavations to carry out blasting plans with a view to controlling the tunnel profile properly and increasing the speed of excavation effectively.
