摘　　要：针对快速掘进工作面粉尘污染严重且高压喷雾除尘效果不佳的问题,结合掘锚一体机镐形截齿截割产尘过程,分析了泡沫降尘机理,设计了快速掘进工作面泡沫降尘系统,并进行了现场应用。泡沫降尘系统制备的泡沫能够有效包裹掘锚一体机截割滚筒并覆盖煤壁来提前湿润煤岩,减少和抑制了粉尘产生,除尘效果比高压喷雾系统明显。In view of the serious dust pollution and the poor effect of dust removal of high pressure spray in the rapid excavation face, combined with the dust production process of the picks cutting pick of the bolter miner, the foam dust removal mechanism was analyzed, and the foam dust removal system for rapid excavation face was designed and applied in the field. The foam prepared can effectively wrap the cutting drum of the bolter miner and cover the coal wall to wet the coal rock ahead of time, reduce and suppress the dust generation, and the dust removal effect is more obvious than that of the high pressure spray system.
