摘　　要：新安煤矿15号煤层煤质酥软,回采巷道传统的沿底布置,顶煤不易管理,存在顶煤随掘随冒的现象,极易形成巷道超高,严重影响掘进效率的同时,造成高冒区瓦斯积聚,存在安全隐患。而采用沿顶掘进解决了随采随冒现象,基本实现了快速掘进,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,也为同类开采条件矿井的回采巷道布置提供了参考。The coal seam quality melted in 15# coal mine, the traditional mining roadway along the bottom arrangement, the top coal is not easy to manage, there exists the phenomenon of top coal along with excavation, it is easy to form the roadway ultra-high, which seriously affects the tunneling efficiency, and causes the gas accumulation in the high caving area, and there The use of along-top tunneling solves the phenomenon of mining with the occurrence, the basic realization of the rapid excavation, from the coal mining process reform, ventilation and production, gas control and other aspects of comprehensive consideration, has obvious safety and economic benefits, but also for the same mining conditions of the mine roadway layout provides a reference.
