摘　　要：基于运输巷道粉尘运移规律的研究,对山西某矿运输巷道风力扬尘与粉尘运移耦合运动进行数值模拟研究,并结合现场测量分析,得出巷道内车辆运行对粉尘运移数值模拟的有效性。数值模拟结果显示:车辆速度越大,巷道的扬尘强度越大,且不同车速影响的范围相差不大;车辆顺风行驶和逆风行驶时,粉尘质量浓度最大时的地点不同;车辆相向行驶过程中,风速越大,底板的扬尘强度越大。Based on the study of dust migration laws in the transport roadway,a numerical simulation was conducted on the coupled motion between the wind dust and the dust migration in a certain mine in Shanxi.Then,combined with the on-site measurement analysis,the effectiveness of numerical simulation of the dust migration during vehicle driving in the tunnel was obtained.The numerical simulation results showed that the vehicle speed would increase with the increase of the dust intensity in the roadway,and the influence range of the vehicle speed was not significantly different.The location of the maximum dust concentration was different when the vehicle was driven along the wind and against the wind.In the process of vehicles moving towards each other,the dust intensity of the floor would increase with the increase of the wind speed.
