摘要
U型和Y型通风方式是目前国内常用的2种通风方式,为了更好的研究两种通风方式下采空区瓦斯流动规律,论文建立了二维计算流体力学模型。应用fluent软件进行数值模拟,系统研究这两种通风方式下采空区流场和瓦斯运移规律,并对模拟结果进行比较分析,得出Y型通风能够更好地治理上隅角瓦斯积聚。
The U-type and Y-type ventilation is commonly used two kinds of ventilation mode, in order to better research the two ventilation modes gob gas flow distribution, the paper established a two-dimensional CFD model. Using fluent software for numerical simulation, and systematic study these two ventilation modes flow field and gas migration law in gob. Simulation results were compared, obtained the Y-type ventilation can better control the upper corner gas accumulation.
