摘　　要：为了解决矿井综掘工作面高浓度粉尘问题,结合矿井综掘工作面产尘特点,在对综掘工作面通风系统进行流场分析后,利用FLUENT软件,对综掘工作面粉尘场进行数值模拟,并分析了粉尘浓度分布规律,依据湿式振旋除尘原理,设计了综掘工作面附壁风筒封闭式除尘系统,并在枣庄矿业集团高庄煤矿3上1101轨道巷综掘工作面进行了现场应用。结果表明,矿井综掘工作面的全尘和呼尘的平均降尘率为93.0%和92.3%,取得了理想的降尘效果。In order to solve the high dust content problem in the fully mechanized mine roadway heading face,in combination of the dust features of the fully mechanized mine roadway heading face,a ventilation flow field analysis was conducted on the ventilation system of the fully mechanized mine roadway heading face.The FLUENT software was applied to the numerical simulation of the dust field in the fully mechanized mine roadway heading face and to the analysis on the distribution law of the dust content.According to the wet type vibration cyclone dust control principle,a suspended air duct closed dust collection system of the fully mechanized mine roadway heading face was designed and applied to the fully mechanized mine roadway heading face of the 3up 1101 rail transportation roadway in Gaozhuang Mine,Zaozhuang Group.The results showed that the average dust control rate of the full dust and respirable dust in the fully mechanized roadway heading face would be 93.0% and 92.3% individually with the ideal dust control effect.
