摘要
依据软岩巷道的破坏机理和支护分析,在主动支护理念的指导下,对安徽淮南潘三矿东四采区-420m总回风巷,采用锚注加固并取得较好技术经济效果的实例进行了理论分析,探讨了软岩巷道的加固方案及相应的巷道锚注加固参数。
According to the failure mechanism, the analysis of supporting in soft -rock roadway and , the concept of initiative supporting, the authors have make a theoretical analysis of the technologically and economically effective practice with bolt - grouting reinforcement at - 420m main return way on East - Four mining area in Pansan Colliery. Also, the authors have explored the reinforcement project on soft - rock roadway and the corresponding parameters of bolt - grouting reinforcement.
