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。
In light of phenomenon including serious back brace, bad surrounding forming effect and low tunneling speed in the mine rock tunne-ling construction process owning to some fault operation including less holing, disorderly holing, irregular charging, and irrational blasting net- work 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.
