摘要
结合大柳煤矿2024工作面运输顺槽实例简要分析了巷道顶板破坏的机理,通过计算巷道顶板支护各项参数,有效解决了顶板支护参数选择的盲目性问题,实际应用中取得了显著的经济效益与社会效益。
Taking conveyor gateway of 2024 working face,Daliu Colliery for example,the paper briefly analyzed mechanism of roadway roof failure and calculated roadway roof support parameters,which effectively solved the blind problem of roof support parameter selection and achieved significant economic and social benefits.
