摘要: 为了研究巷道分岔对烟气蔓延至回风大巷温度、压强以及风速的影响,基于Pyrosim火灾模拟软件,模拟了回风斜巷和回风大巷交汇形式以及巷道分岔角对烟气蔓延的影响。结果表明:当vg (工作面风速)Abstract: To research the influence of diverging angles on the temperature, pressure and wind speed of smoke flow on the return airway, this paper simulates the influence of the return airway and return inclined roadway intersections and diverging angles on flue gas propagation based on Pyrosim. The results show that when vg
