苏联《玛依库杜科》煤矿六采区采用辅助通风顺槽对回采工作面进行通风,大大地改善了采区的通风状态并提高了煤产量。其做法是:顺煤层倾斜距回风巷6～10米并平行于回风巷掘送一条辅助顺槽,用于供给工作面上端新鲜风流,其巷道布置如下图,六采区开采 Κ_4煤层,开采深度367米,采厚1.7米,煤的灰分26.5%,平均密度 Ventilation of coal mining face with auxiliary ventilation slots in the sixth coal mining area of ​​the Soviet Union “Maikudduco” greatly improved the ventilation status of the mining area and increased the coal output. The approach is: 6 ~ 10 m away from the return airway inclined coal seam parallel to the return airway dug an auxiliary trough for the supply of fresh air flow at the top of the work surface, the layout of the roadway as shown below, six mining area mining K_4 seam, Mining depth of 367 meters, mining thickness of 1.7 meters, coal ash 26.5%, the average density
