针对大采高工作面采煤机截割产尘污染现状，以三道沟煤矿85219综采工作面为例，对不同截割湍流风影响下的前、后滚筒粉尘运移规律进行数值模拟分析，并对比了顺风与逆风截割对工作面湍流粉尘扩散的影响作用。结果表明：顺风作业时，横向偏移速度增加对前滚筒影响更大；逆风作业时，横向偏移分速度对前后滚筒的影响更显著；顺风割煤时，前滚筒产尘浓度随垂直高度降低而减小，后滚筒则增大，逆风割煤情况相反；截割湍流风增大，人行道粉尘质量浓度随扩散范围增大而减小；顺风截割后滚筒产尘是主要粉尘来源，截割湍流风由小增大，人行道环境影响因素由前滚筒变为后滚筒，逆风截割与之相反；现场粉尘测定平均值与数值模拟结果相比，整体误差在20%以内，绝大多数误差低于10%。

Taking Sandaogou Coal Mine 85219 fully mechanized coal mining face as an example, the dust migration rules of the front and rear cylinders under the influence of different cutting turbulent wind conditions were numerically simulated, and the effects of downwind and upwind cutting on the diffusion of turbulent dust on the working face were compared. The results show that the increase of the lateral offset speed has a greater effect on the front cylinder during downwind operation. When operating against the wind, the lateral offset velocity has a more significant effect on the front and rear rollers. When cutting coal downwind, the dust concentration of the front drum decreases with the decrease of the vertical height, while the rear drum increases, but the opposite is true when cutting coal upwind. With the increase of cutting turbulent wind, the dust mass concentration of pavement decreases with the increase of diffusion range; the dust produced by the roller after downwind cutting was the main source of dust, the turbulence wind of cutting increased from small to big, and the influencing factors of sidewalk environment changed from front roller to back roller, while the opposite was true for upwind cutting. Compared with the numerical simulation results, the overall error of in-situ dust measurement is less than 20%, and most of the errors are less than 10%.
