| 摘 要： | 对瓦斯在煤层中流动、在邻近煤层和围岩中流动规律进行分析；总结出采空区瓦斯分布规律。引入地质变化连续函数，更加准确地建立了采空区瓦斯渗流模型，利用CFD软件进行模拟解算，研究了采空区瓦斯渗流场变化规律，并通过对比确定了一种计算模型。研究表明：采用CFD模型研究采空区瓦斯渗流规律是可行的方法之一。

CFD Simulation of Gas Seepage Regularity in Goa |
| |
| Abstract: | The distribution law of gas was summarized through the analysis on the gas flowing in the coal seam,adjacent coal seam and the surrounding rock.Continuous function of geologic changes was imported,the seepage model was established in mined area more correctly.The change law of seepage field of methane in mined out area was researched on the simulated calculation by CFD,and chose one model by comparing.It suggests that studying goaf gas seepage applying CFD model is one of the feasible methods. |
