Abstract：In order to solve the high dust mass concentration problem of the fully-mechanized coal mining face in coal mine,taking No. 2225 fully-mechanized coal mining face of Xingdong Mine as a study object,based on the mathematics model,a fully-mechanized coal mining face was established.The FLUENT software was applied to the numerical simulation to analyze the air velocity affected to the dust migration law of the fully-mechanized coal mining face.The study results showed that in a certain air velocity scope,with the air velocity increased,the average dust mass concentration of the fully-mechanized coal mining face would steadily reduced. But the air velocity too high would also cause a negative influence to the working environment and condition.Therefore,an air velocity of 2 m/s at the air inlet was determined as the optimized air velocity and under the condition of working environment not influenced,the dust mass concentration would be minimum.
