摘　　要：介绍了目前国内外常用的6种长距离局部通风技术,指出双巷平行掘进、全风压与局部通风机相结合的长距离局部通风以及构筑风库的局部通风技术,由于其通风可靠和掘进通风距离不受限制,将会成为大型矿井长距离局部通风的主要技术;在特定的条件下,钻孔导风的局部通风技术具有较好的技术和经济效益;随着柔性风筒的减漏和降阻技术的进一步完善,在掘进距离小于3 000 m的范围内,单风机大直径柔性风筒压入式局部通风、通风机间隔串联局部通风和通风机并联局部通风技术仍然是最常用的长距离局部通风技术。The paper stated the present common applied six long distance local ventilation technologies at home and abroad.Due to the ventilation reliability and the heading ventilation distance with no restriction,the paper pointed out that the double roadways simultaneous heading,the full ventilation pressure and the local ventilator combined long distance local ventilation and the local ventilation technology to set up the ventilation reservoir would be the main technology of the long distance local ventilation in the large coal mine.Under the certain conditions,the local ventilation with the borehole pilot ventilation would have good technical and economic benefits.With the leakage reduction and resistance reduction technology of the flexible duct further improved,within the heading distance less than 3 000 m,the forced local ventilation with large diameter flexible duct of a single ventilator,the interval series local ventilation of the ventilator and the ventilator parallel local ventilation technology would be the most common long distance local ventilation technology.
