摘    要:为了掌握粉尘的分布规律,根据气固两相流理论,针对矿井掘进工作面的特点,采用计算流体力学的离散相模型(DPM)对压入式通风掘进巷道中粉尘浓度进行了数值模拟.由此总结出压入式通风掘进巷道中全尘和呼吸性粉尘浓度都是在工作面附近区域较大,然后沿程逐渐减小,并比较发现,抽出式通风的除尘效果要好于压入式通风.

关 键 词:压入式通风  粉尘浓度  数值模拟  气固两相流  离散相模型  掘进工作面

Abstract:For gripping the distribution regularities of the dust, based on the theory of two-phase flow of gas and solid,and the characteristics of coal mine driving working face,using the discrete phase models of computational fluid mechanics to simulate the dust concentration during the ventilation process of coal roadway driving with forced ventilation.Summarize that in the coal roadway driving with forced ventilation,both of the concentration of whole dust and respirable dust are more in the area close with the working face,then the concentration will decrease as it moves to the exit of the roadway;by comparing,find that exhaust ventilation is better than forced ventilation in dust removal.
Keywords:forced ventilation  dust concentration  numerical simulation  two-phase flow of gas and solid  discrete phase models  driving working face
