摘要
巷道掘进在过大断层带时必须对顶板岩性及稳定性进行分析研究,并制定一套合理有效的支护措施,方可保证施工巷道安全顺利通过断层带。本文以屯兰矿南六回风准备巷施工过土地沟断层为例,浅析了施工巷道过大断层支护设计优化。
When roadway driving is in the large fault zone, it is necessary to analyze and study the lithology and stability of the roof, and draw up a set of reasonable and effective supporting measures to ensure the safe and smooth passage of the construction through the fault zone. This paper takes the South six return air tunnel that passes through tudigou fault as an example, and analyzes the optimization design of the large fault support of the construction roadway.
