近距离保护层Y型通风工作面瓦斯抽采数值模拟研究

Numerical Simulation of Gas Drainage in Close Protection Layer Face With Y-type Ventilation

为了研究Y型通风近距离保护层采场的瓦斯浓度分布规律,以新庄孜煤矿62114保护层开采现场条件为基础建立模型,运用Fluent软件进行数值模拟研究。模拟获得了有抽采和无抽采条件下采场瓦斯浓度分布规律,为现场瓦斯治理工作提供了方向和理论依据。

To study the gas concentration distribution principles of close protective layer with Y-type ventilation,the models are built with the field conditions of No.62114 protective layer in Xinzhuangzi Coal Mine.Numerical simulations are performed by using the Fluent program.The simulations give the gas concentration distribution rules with and without the drainage work.The results provide a guidance and theoretical basis for on-site gas control system.
