摘要
针对高硬度岩石巷道掘进工程,对掏槽方式的传统工艺进行改进,根据实验对比、分析,结果表明六角星型掏槽方式更适合本矿山。这种掏槽方式提高了巷道掘进效率和速度,使工程达到预期效果。
In view of the high hardness rock roadway excavation project, the traditional cutting method is improved. According to the experimental comparison and analysis, the results show that the hexagonal star cutting method is more suitable for this mine. This cutting method improves the efficiency and speed of roadway excavation, and achieves the expected effect of the project.
