摘要
采用CFD(计算流体力学)数值模拟的方法确定1412(1)工作面采空区在无抽采、有抽采两种条件下的瓦斯浓度分布规律,将采空区看作为多孔介质区域,并通过现场实测以及理论计算确定模拟所需参数。运用FLUENT软件对无抽采以及采空区埋管抽采瓦斯条件下的采空区进行数值模拟,分别得出其浓度分布规律,并对这两种情况下的数值模拟结果进行对比分析,使我们对其分布规律的异同点有深刻的了解,同时为今后的采空区瓦斯治理工作提供了参考依据。
Goal gas concentration distribution patterns at Panel 1412（1）were studied by means of com- putational fluid dynamics （CFD） numerical simulation. Considered two kinds of situations, one was simulated by buried pipe drainage in mined-out area, and the other was simulated without drainage. Goal was regarded as porous medium, and simulation parameters we needed were based on field meas- ured data and theoretical calculation. Compared and analyzed the two simulation results,we got a deep understanding of the similarities and differences of gas concentration distribution patterns. It will pro- vide reference for the future work of gas control by the comparative analysis.
