摘　　要：煤层倾角在0～32°内变化,突出瓦斯相似模拟实验结果,看不出上行风和下行风对进风平巷风流逆流现象有何差别.根据瞬变流理论导出一维非定常流动数学模型,运用特殊全微分方程求出突出瓦斯对进风流的影响与实际相符.The results of the gas outburst simulation experiments showed that there was no difference in an air-flow reverse phenomenon in air inflow roadway between the upward ventilation and downward ventilation when the seam angle is ranging from 0 to 32°. According to the transient hydrodynamics theory, an one dimension non stable flow mathematic model was evolved and with a special full differential equation,the outburst gas affected to the incoming air flow and practices were calculated.
