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.
介紹瞭礦山巷道掘進光麵爆破試驗的情況,通過實測確定採用YT-29型鑿巖機鑿鑽砲孔,給齣瞭光麵爆破參數和工作麵砲孔佈置.80 m長巷道掘進實踐錶明,該條件下,加深砲孔的光麵爆破效果良好.

This paper introduced the experiments of smooth blasting in driving of tunnel in mining.Through the observation,the YT-29 drilling machine was ehoosed 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.
