Numerical simulation of the dust movement rule in fully-mechanized coal faces

  • 摘要: 运用气固两相流动理论,建立粉尘运动的数学模型.根据综采工作面的具体特点和实测数据,采用计算流体力学的FLUENT软件,对工作面的粉尘运动规律进行数值模拟.模拟结果显示,粉尘产生后多数随风流在煤壁一侧运动,少数粉尘随机扩散.综采工作面的除尘重点应该放在采煤机下风向10m以内的煤壁一侧;预湿煤壁对降低工作面粉尘浓度也有很大作用.
    Abstract: A mathematical model of dust movement was derived from the gas-solid two-phase flow theory. According to characteristics of the fully-mechanized coal face in mines and related survey data, numerical simulation of the dust movement rule was made with CFD software FLUENT. The result shows that most of dust moves with wind, and little of dust disperses at random. Dust control in the work face should focus on the place within 10 m under the coal mining machine near the coal wall, and wetting the coal face before coal cutting is also important for dedusting.
