Simulation of Dust Mass Concentration Changes Based on FLUENT in Comprehensive Excavation Working Face
The dust hazards in coal mines in China are serious,and comprehensive excavation working face is an important dust producing location.In the article,numerical simulation of the dust in the 1402 comprehensive excavation working face of Xin'an Coal Industry Co.,Ltd.was conducted using fluent,and the transport law of the dust in the working face was obtained.Research has shown that the dust mass concentration in the comprehensive excavation working face is the highest,and the dust mass concentration near the comprehensive excavation machine is unstable.After the excavation machine,the dust mass concentration decreases with the increase of distance from the working face.The technical measures of setting spray near the roadheader to reduce dust are put forward.
