摘要
介绍了矿山巷道掘进光面爆破试验的情况,通过实测确定采用YT-29型凿岩机凿钻炮孔,给出了光面爆破参数和工作面炮孔布置。80 m长巷道掘进实践表明,该条件下,加深炮孔的光面爆破效果良好。
This paper introduced the experiments of smooth blasting in driving of tunnel in mining. Through the observation, the YT-29 drilling machine was choosed and then put forward the smooth blast parameters and boreholes pattern. The practice of driving of 80 m tunnel shows that the deepened holes should result in good results.
