摘要
基于大断面岩石巷道掘进速率相对于其他类型巷道掘进速率极低的问题,本文通过对大断面全岩的特点及主要机械化作业线的现状和优缺点进行分析研究,有效解决了深部巷道爆破及支护上存在的一些技术难点,不仅保证了巷道的掘进安全,而且大大提高了矿井巷道施工效率。
Based on the problem of low roadway tunneling rate with the large section is very low compared with other types,. Based on large section of whole rock characteristics and the advantages and disadvantages of the status main machine operation line were analyzed,which effectively solved a number of technical difficulties of the blasting and supporting in deep roadway, and not only to ensure that the roadway driving safety, and greatly improve the efficiency of mine roadway construction.
