摘　　要：矿车的运动对巷道粉尘的浓度分布很大,尤其是在风流的影响下,针对逆风、无风和顺风的情况,运用Fluent对巷道中粉尘的分布规律进行模拟仿真。结果表明:矿车运行时,巷道两壁和上方空间会产生大量粉尘;顺风矿车时,巷道粉尘浓度分布比较均匀;逆风矿车时,巷道粉尘主要集中于矿车尾部,对其研究为更好地设计和布置喷雾降尘装置提供了参考。The influence of harvester movement on the dust concentration distribution in roadway is very big,especially under the wind.In the aspect of against,with and without the wind,the influence of harvester movement on the dust concentration distribution in roadway is simulated by using the Fluent software.Results show that two wall of roadway above space can produce a large amount of dust when the harvester is running.When with the wine,the roadway dust concentration distribution has more uniform; when without the wine,the roadway dust mainly is focused on the tail,the research provides the reference for design and arrangement of spray dust device better.
