摘　　要：介绍了一种由乳化液马达驱动的新型矿用瓦斯吹排风机,其独特的结构能更安全有效地吹排工作面上隅角积聚的瓦斯。通过流场测量和数值方法模拟了不同动叶安装角下风机的内部流场,为风机的进一步改良提出了建议。A new type of fan for blowing gas in coal mine driven by the emulsion motor was introduced . The fan can blow gas in upper comer safely and effectively because of its unique structure and make a good effect in field experiments. The flow fields inside fan with different blade incidences are achieved by experiment and numerical simulation. Meanwhile, some advices are given to improve the fan＇s performance.
