走向高抽巷抽放瓦斯技术研究

摘要

Aiming at the actual situation of a certain coal mine in Handan Hebei province, towards high alley pumping methane drainage Technology are studied: ① numerical simulation for methane flow in the system towards high alley pumping methane drainage was carried out by FLUENT, vertical height of strike high-position alley above the roof and horizontal distance to the return in incline direction was determined. ② during tunnel drainage, seal of the tunnel drainage system should be applied to improve the performance, the waterseal drainage system was proposed in this condition. . The paper there will be considerably instructional significance to the similar mine.%结合邯郸某矿的实际状况,对走向高抽巷瓦斯抽放技术进行了研究:①采用FLUENT软件对采用走向高抽巷抽放瓦斯的系统进行了数值模拟分析,确定了走向高抽巷的垂高和倾斜方向位置.②对巷道抽放瓦斯密封系统进行了改进.论文的研究为其他矿井采用高抽巷对煤矿瓦斯进行抽放有一定参考意义.
