摘要
通过对池坪芦坑煤矿+800 m集中运输巷的试验可以得知,采用中深孔爆破作业能够对坚硬岩的爆破起到很好的效果,且工效高,巷道成形质量好,值得被推广和运用。
Based on Chipinglukeng Coal Mine ＋ 800 m concentrated transportation lane test learn that using middle deep hole blasting operation can to a hard rock blasting have very good effect, and high efficiency, roadway forming of good quality and worthy of popularization and application.
