摘　　要：通过对石港矿东回风大巷掘进期间煤壁暴露面和落煤的瓦斯涌出强度与时间的关系进行现场测试和理论研究,得出掘进巷道瓦斯涌出量与掘进长度、掘进速度的关系式,为该矿今后的巷道掘进确定合理的通风方式和通风参数提供依据。Through local testing and analysing of quantity of gas emission from exposed coal walls and fallen coal during the period of east main return airway drifting in Shigang Coal Mine, some mathmatical relationships of quantity of gas emission of drifting face with drifting length and speed are reached, which serve for ensuring drifting and determinating of ventilaion types and parameters.
