摘　　要：掘进工作面作为煤矿井下重要的作业地点,良好的通风状况对于除尘和排瓦斯至关重要。基于粉尘与瓦斯气固两相流动理论模型,数值模拟不同风筒布置和不同风速情况下,粉尘和瓦斯在掘进巷道的时空运移规律以及最大浓度分布,定量比较不同送风参数对除尘和排瓦斯效果的影响,对局部通风机的布置和瓦斯治理具有指导意义。As an important working place in coal mines,driving roadway has good ventilation is very important for dust removal and gas drainage.Based on the theoretical model of gas-solid two-phase flow of dust and gas,the temporal and spatial migration law and maximum concentration distribution of dust and gas in tunneling roadway under different duct layout and different wind speeds are numerically simulated,and the effects of different air supply parameters on dust removal and gas drainage are quantitatively compared,which has guiding significance for the layout of local fans and gas control.
