摘要
为降低破碎带给巷道掘进及使用造成的不利影响,在对巷道遇断层掘进、围岩变形影响特征及构造应力测量分析基础上,提出以强顶板为核心的围岩控制措施,制定巷道围岩控制方案及施工技术要求。采用提出的围岩控制措施后,巷道过断层破碎带时围岩变形量最大为86mm,支护措施可以满足巷道掘进安全需要。
In order to reduce the disadvantageous influence of roadway excavation and use caused by crushing,based on the analysis of roadway driving with fault,surrounding rock deformation characteristics and structural stress measurement,the surrounding rock control measures with strong roof as the core are proposed,and the control scheme and construction technical requirements of roadway surrounding rock are formulated.After adopting the control measures,the maximum deformation of surrounding rock is 86mm when the roadway passes through the fault fracture zone,and the supporting measures can meet the safety needs of roadway excavation.
