摘　　要：本文以潞安煤矿为例,针对煤矿巷道产生的粉尘,设计了矿井粉尘过滤系统,监测了8种常用风管布置方式下的粉尘浓度。研究表明,当抽采风管进口距离掘进工作面3 m、制风管出口距离掘进工作面13 m时,矿井粉尘过滤系统除尘效果最佳,总粉尘和呼吸性粉尘的平均浓度明显降低,极大地改善了煤矿巷道环境。This paper taking Lu'an Coal Mine as an example,a dust filtration system was designed to monitor the dust concentration under 8 common air pipe arrangements.The research shows that when the inlet of the extraction air pipe is 3 m away from the driving face and the outlet of the air pipe is 13 m away from the driving face,the dust removal effect of the mine dust filtration system is the best,the average concentration of total dust and respirable dust is significantly reduced,and the coal mine roadway environment is greatly improved.
