摘要
应用FLUENT软件对综采工作面双U形通风方式采空区瓦斯运移规律进行数值模拟,得出采空区走向方向、垂直方向和倾斜方向瓦斯浓度分布规律;进而发现采空区内高浓度瓦斯富集带,瓦斯浓度最高可达85%左右,为瓦斯抽采合理位置的确定提供了理论依据。
In application of FLUENT software through the numerical simulation to the gas migration rules on the double U-shape ventilation method of the fully mechanized working face in the goaf area,the rules of the gas concentration distribution of the goaf towards direction, vertical direction and tilt direction are obtained; and then the gas enrichment zone of high concentrations in the goaf area is founded where the gas concentration can be up to approximately 85%,which is regarded as the theoretical basis for the determination of the reasonable gas extraction location.
