| 摘 要： | 针对煤矿井下瓦斯传感器的安放位置参数缺乏提供理论依据，首先建立了巷道几何模型，根据湍流状态下的守恒方程以及湍流动能方程和湍流耗散率方程以及标准k-ε模型，仿真了井下巷道数值方向上瓦斯的分布情况.通过比较巷道纵断面瓦斯的分布情况，得出：瓦斯传感器应放置在距顶板小于等于0.3 m的位置.该结论与煤矿安全标准中的规定吻合.

| Abstract: | To provide theory base of methane sensor placement in vertical direction in tunnel， methane distribution in level sections and vertical sections was simulated using standard k-ε model by Fluent according to conversation equation in turbulent state， turbulent kinetic energy equation and turbulent dissipation rate equation. Standard k-ε model and Fluent software was used to simulate methane distribution according to the principle of conversation equation in state of turbulent flow. By comparing methane distribution in vertical sections, the simulation result shows distance of sensor to roof should be no more than 03 m which accords with the mine safety regulations well. |
