摘　　要：文章根据我国矿井发展趋势,通过对薄煤层高产高效回采工作面生产的特点以及现阶段工作面通风方式的缺点进行分析,提出了“双U”型通风,并对该通风方式的基本概念、巷道布置、优缺点、适用条件等进行了分析,认为“双U”型通风方式适用于产量大、瓦斯涌出大、工作面需风量大的薄煤层高产高效回采工作面。According to the mine development trend in China ,the authors bring forward the double-U ventilation mode after analyzing the yielding characteristic of the productive-efficient working face with thin coal seam along with the disadvantage of ventilation in the working face nowadays. At the same time, the authors introduce the conception, the laneway layout, the disadvantage and the excellency and the applicable condition for the double-U ventilation mode. The authors think that the double-U ventilation mode is suitable for the productive-efficient working face of high-gassy and air-need with thin coal seam.
