摘　　要：隆华煤业15#煤层煤质酥软,15102胶带顺槽沿煤层底板布置时,存在托顶煤困难,随掘随冒的现象,造成巷道超高、掘进效率降低,且形成高冒区造成瓦斯积聚,存在安全隐患。15102轨道顺槽采用沿顶掘进解决了托煤困难,随掘随冒现象,实现了快速掘进,从采煤工艺的改革、通风和生产、瓦斯治理等方面综合考虑,具有明显的安全和经济效益。The coal quality of 15#coal seam of Longhua Coal Industry is soft.When 15102 tape is arranged along the coal seam floor,it is difficult to support the top coal and the phenomenon of rising with excavation occurs,resulting in the roadway being too high,the excavation efficiency is reduced,and gas accumulation is formed in the high-risk area,which has security risks.15102 track(return air)channeling along the top to solve the problem of coal support,along with the phenomenon of mining with the rise,to achieve rapid tunneling.Taking into account the reform of coal mining technology,ventilation and production,and gas control,it has obvious safety and economic benefits.
