摘　　要：采煤工作面过落差8 m的大断层,一次性最大揭露60架全岩,严重制约了工作面安全生产。为此,高煤公司采用高强截齿提升煤机破矸能力和效果,采用深孔预裂方式替代传统打眼放炮,超前锚索支护加强顶板维护等,工作面安全高效通过大断层。The working face passes through a large fault with a fall of 8 m,and the maximum exposure of 60 whole rocks at one time seriously restricts the safe production of the working face.For this reason,high-strength pick is used to improve the gangue breaking capacity and effect of coal mining machine,deep hole presplitting method is used to replace traditional drilling and blasting,advanced anchor cable support is used to strengthen roof maintenance,etc.,so that the working face can pass through large faults safely and efficiently.
