摘　　要：文章对筛分车间内在气流中的粉尘进行了受力分析,并分析各力对粉尘运动轨迹的影响,在此基础上,建立了选煤厂筛分车间粉尘运动轨迹方程。通过计算得知在筛分车间内粉尘的运动扩散主要是受到气流曳引力、粘性阻力、虚假质量力、Basset力和旋转升力的作用。这将为选煤厂筛分车间的粉尘治理工程提供理论支持。The paper had a stressed analysis on the dust in air flow of the screening shop and analyzed the each force affected to the dust moving traces. Base on the above base, the paper established the equation of the dust moving traces in the screening shop of the coal preparation plant. The calculation showed that the moving spreading of the dust in the screening shop was mainly affected by the air traction force, viscous resistance, fictitious mass force, Basset force and rotary lift force, which could be the theoretical support to the dust control project of the screening shop of the coalpreparation plant,
