摘要
通过对永红煤矿工作面U+L形通风和双U形通风的介绍,应用Fluent软件模拟了这2种通风的瓦斯分布。结果表明,双U形比U+L形风排瓦斯能力更强,上隅角瓦斯和尾巷浓度处于安全范围之内,且安全系数高;其具有更高的抗灾能力和安全性能,保证通风系统安全可靠运行。
With the introduction to U+L ventilation and double U ventilation in Yonghong Coal Mine,the Fluent software was applied to simulate gas distribution with the two ventilation mentioned above.The results indicate that double U ventilation has larger ventilation capability to discharge gas than U+L ventilation so that gas concentration of the upper corner and tail roadway were in a safe range which has high safety coefficient. Double U ventilation has higher anti-disaster capability and safety performance to ensure the ventilation system being safe reliable.
