| 摘 要： | 采用CFD软件对巷道局部高顶瓦斯积聚进行三维数值模拟,模拟结果直观显示了局部高顶内风速较低、涡旋的存在和高浓度瓦斯的积聚状态,并重点模拟计算了采用导风板治理局部瓦斯的效果,最终得出采用导风板30°倾斜设置可有效消除高顶瓦斯积聚的最优方案。

| Abstract: | This paper adopts Computational Fluid Dynamics software to simulate methane accumulation and diffusion in partial roadway.The result of sumulation intuitively shows that the vortex exist in the roof zone,wind speed is quite low and methane is accumulated.The reseach mainly discusses the effect of air brattice in preventing methane accumulation in partial roadway.It obatins the best project that using air brattice in 30 degree gradient settings can effectively eliminate the methane in partial roadway finally. |
