| 摘 要： | 本文探讨了在特硬岩立井掘进爆破中的掏槽方式以及现场应用情况。对2．3m炮孔爆破与2．8m炮孔爆破的掘进速度、直接作业成本作了定量的对比分析。试验表明：强力复合掏槽在特硬岩立井掘进爆破中应用效果良好；2．3m炮孔比2．8m炮孔爆破的掘进速度更高、作业成本更低。

| Abstract: | In this paper,cutting form and its actual application in sinking and blasting of hard rock shaft are discussed.The sinking and blasting velocity and cost for 2.3?m and 2.8?m hole depth are contrasted by quantitative analysis.The results show that mighty compound cutting can give a good effect of sinking and blasting in hard rock shaft,and sinking velocity adopted for 2.3?m hole is higher and its production cost is lower than that of 2.8?m hole. |

| Keywords: | shaft sinking and blasting production cost mighty compound cutting sinking velocity |
