| 摘 要： | 针对某矿岩巷掘进施工过程中的少打孔、乱打孔、装药不规范、起爆网路不合理造成的超欠挖严重、周边成形效果差、掘进速率低的现象,通过不断调整施工方案,选择出了合理的炮眼布置方式和正确的起爆网路,从而显著的提高了爆破效果和掘进速率。

| Abstract: | In light of phenomenon including serious back brace,bad surrounding forming effect and low tunneling speed in the mine rock tunneling construction process owning to some fault operation including less holing,disorderly holing,irregular charging,and irrational blasting network and so on,through constantly adjusting the construction scheme,the paper finally determines rational borehole layout methods and correct blasting network.As a result,it obviously improves the blasting effect and tunneling speed. |
