Study on Distribution Law of Oxidation Zones in Goaf Based on Fluent

根据风流在采空区内流动情况建立合理的数学模型和物理模型,应用控制变量法分析孔隙率、风速、工作面长度、瓦斯涌出量等4个因素对氧化带的分布规律的影响,并使用CFD软件Fluent对不同变量的采空区进行数值模拟,利用漏风风速指标对氧化带进行划分,得出孔隙率、风速、工作面长度、瓦斯涌出量等4个因素的改变对采空区氧化带分布规律的影响。

According to the flow of wind in the goal, the reasonable mathematical model and physical model are established.The influence of four factors such as porosity,wind speed,working face length and gas emission amount on the distribution of oxidation zone is analyzed by the control variable method. And the CFD software Fluent was used to simulate the mined-out area of different variables.The factors such as porosity,wind speed, working face length and gas leakage wind speed index, with the impact of the distribution emission were obtained by using the air law.
