摘要
利用计算流体力学(CFD)软件Fluent对6206综放面回采不同区段时采空区瓦斯流场及浓度分布进行了数值模拟,得到了"J"型通风条件下的采空区流场及瓦斯运移规律。结果表明,采用"J"型通风系统可减少采空区向上隅角的集中漏风,对有效解决工作面上隅角瓦斯积聚有着重要的作用。
Application of a numerical simulation on goal gas flow field and concertration distribution at 6206 fully mechanized face min- ing by using of computational fluid dynamics （CFD） software Fluent at different sections, and gain migration rule of goal flow field and gas under the conditions of ＂J＂ type ventilation. The results showed that the use of ＂J＂ type ventilation system can reduce goat＂ concentration of air leakage upper corner,it plays an important role of effective solution to the accumulation of gas upper comer.
