摘　　要：煤矿巷道掘进是否能够安全稳定地进行,直接影响着井下作业效率,但随着煤炭产业的不断发展,我国煤矿开采难度也在逐渐提升,井下环境越来越复杂,比如在掘进过程中如果遇到破碎顶板而没有进行有效支护很容易引发严重安全事故,因此开展巷道掘进工作过程中需要通过临时支护提升工作面破碎顶板的稳定性。以此为出发点,阐述了矿井掘进工作面顶板破碎断巷道临时支护措施,为相关工程实践提供参考。Whether the excavation of coal mine tunnels can be carried out safely and stably directly affects the efficiency of underground operations.However,with the continuous development of the coal industry,the difficulty of coal mining in China is gradually increasing,and the underground environment is becoming increasingly complex.For example,if a broken roof is encountered during the excavation process without effective support,it is easy to cause serious safety accidents,Therefore,during the process of tunnel excavation,it is necessary to enhance the stability of the fractured roof of the working face through temporary support.Taking this as the starting point,this paper elaborates on the temporary support measures for the broken roof roadway of the mining excavation working face,providing reference for relevant engineering practices.
