    曲江井-822m总回石门在深部掘进,压力大,巷道还需要穿过F1、F4大断层,围岩以炭质页岩为主,断层附近及断层破碎带中顶板压力特别明显,顶板岩石随掘随冒,结合施工现场特殊的地质条件,采用具有针对性的支护方式,实现安全生产。

    In view of the geological conditions in construction site of deep heading at-822 m general return crosscut,such as need of crossing F1 and F4 fault,obvious roof pressure near or in fault fracture zone,and breakage of roof rock at all times because of carbonaceous shale-oriented adjoining rock,the authors probe into adopting focused support patterns to realize production safety.
