摘要/Abstract

摘要： 为探究综掘机配套抽风口位置对巷道除尘效果的影响,利用FLUENT软件建立综掘巷道相似几何模型,开展粉尘从不同尘源位置释放时,压入式通风系统和综掘机配套抽尘系统的流场及粉尘场模拟研究。结果表明:综掘工作面压入式通风系统的粉尘扩散范围在距工作面1～2 m处;综掘机配套抽尘口位置在距工作面1 m时的风流特征最利于除尘且此时各个尘源位置巷道内的粉尘均得到明显改善;当采用综掘机配套抽尘技术后,综掘工作面各个尘源释放粉尘时,巷道内的总体粉尘质量浓度都得到降低,平均除尘效率在80%以上,最高可达93%,可以很好地满足煤矿井下的降尘要求。

Abstract: In order to study influence of suction opening location of integrated excavating machine on dust removal effect of roadway, a similar geometric model of roadway was established by using FLUENT software, and simulated researches on flow field and dust field of press-fit ventilation system and dust extraction system of integrated excavating machine were developed when dust was released from different dust sources.The results show that dust diffusion range of press-fit ventilation system of fully mechanized excavation face is 1-2 m away from head. Wind flow characteristics of suction location of integrated excavating machine at 1 m from head are most favorable for dust removal, and position of each dust source at this time dust in the roadway has been significantly improved. Dust extraction experiment of integrated excavating machine has also verified simulation results well. After adopting dust extraction technology of comprehensive excavator, overall dust concentration in the roadway is reduced when dust is released from various dust sources in the fully mechanized excavation face, and average dust removal efficiency is above 80%, up to 93%, which can well meet the dust reduction requirements of coal mines.

Key words: dust source location, suction opening, fully-mechanized excavation face, collection efficiency, dust distribution
