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。
針對某礦巖巷掘進施工過程中的少打孔、亂打孔、裝藥不規範、起爆網路不閤理造成的超欠挖嚴重、週邊成形效果差、掘進速率低的現象,通過不斷調整施工方案,選擇齣瞭閤理的砲眼佈置方式和正確的起爆網路,從而顯著的提高瞭爆破效果和掘進速率。
침대모광암항굴진시공과정중적소타공、란타공、장약불규범、기폭망로불합리조성적초흠알엄중、주변성형효과차、굴진속솔저적현상,통과불단조정시공방안,선택출료합리적포안포치방식화정학적기폭망로,종이현저적제고료폭파효과화굴진속솔。
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.
