煤矿硬岩掘进中爆破参数的优选实践

摘要

According to the present situation of coal mine hard rock roadway excavation, starting from the factors that affect rock roadway blasting effects, this paper analyzes the factors affecting rock roadway excavation speed and quality such as blasthole depth, cut blasting and smooth blasting through the practical exploration, works out the more reasonable cutting form and cut blasting parameters and the parameters of smooth blasting.%针对煤矿在坚硬岩石巷道中掘进，从影响岩巷爆破效果的等因素出发，对影响岩巷掘进速度和巷道质量的炮眼深度、掏槽爆破和光面爆破等问题进行了分析和实践探索，总结了较为合理的掏槽形式和掏槽爆破参数及光面爆破参数。
