【Abstract】 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.更多还原
