摘　　要：针对某煤矿因局部通风机供电系统存在的可靠性低而可能造成工作面停风形成瓦斯集聚的问题,对造成工作面停风的原因进行了分析,并针对停风原因提出了安装双风机双电源及自动切换装置、延伸"三专"供电和"双三专"供电的改进措施。经现场应用表明,此改进有效提高了煤矿局部通风机供电系统的可靠性。In view of the low reliability of local fan power sup ply system in coal mine and the problem of gasagglomeration caused by the air stoppage in the working face, the causes of the air stoppage in the coal face areanalyzed. The improvement of installing double power supply and automatic switching device for double fan andextending ＂three special＂ power supply and ＂double three special＂ power supply is put forward. The field applicationshows that the improvement can effectively improve the reliability of local fan power supply system in coal mine.
