摘　　要：针对某煤矿双U型通风系统对瓦斯治理的不足,在N2105工作面采用Y型通风系统,对该工作面倾向、上隅角、沿空留巷段瓦斯涌出及分布规律进行研究,并结合Fluent软件进行流体模拟分析处理,结果表面研究结果表明:当胶带顺槽比回风顺槽配风比为1:3即(胶带顺槽和回风顺槽的配风量分别为900m3、2700m3)时,采空区整体瓦斯浓度最小,工作区域的上隅角产生区域涡流现象及其影响范围达到最小,同时其通风、除尘效果也最好。In a double u-shape ventilation system for gas control in coal mine, in N2105 face using Y type ventilation system, on the face orientation, Angle, for the period of gas emission and distribution laws are studied, and combined with Fluent software fluid simulation analysis,the results the study results show that the surface than the return air along the trough when the adhesive tape transportation tunnel air distribution ratio of 1：3 namely（tape along the groove and the return air along the trough with air volume of 900 m3, 2700 m3） respectively, the goaf gas concentration minimum whole, work area regional eddy current phenomenon and its effects in upper corner of the range of minimum, at the same time its ventilation and dust removal effect is best.
