摘　　要：为提高坚硬岩层巷道掘进效率及安全保障能力,以山西某矿南三采区集中回风巷掘进为工程背景,提出采用CMZY4-200/35钻装锚掘机+中深孔爆破组合方式掘进,并依据现场情况对巷道掘进方案进行设计。应用该方案后,南三采区集中回风巷掘进进尺平均为95.6 m/月,作业人员数量减少18人,取得较好的应用成果。In order to improve the efficiency and safety guarant ee ability of hard rock tunneling,the combination of CMZY4-200/35 drilling anchor digger+medium-deep hole blasting is proposed for tunneling in the south three mining area of a mine in Shanxi Province as the engineering background,and the tunneling scheme is designed according to the site conditions.After applying the scheme on site,the average length of tunneling progress of the centralized return air tunnel in the south third mining area is 95.6 m/month,and the number of workers is reduced by 18,which is a good application result.
