双U型工作面两进两回通风方式在岳城煤矿的应用分析

摘要

With the increase of a mine production capacity, gas has become an important factor restricting the release of production potential of a working face,especially in high gassy mine. This paper analyzed the application of the ventilation pattern with two air-intake and air-return ways in 1310 ( upper) double U-shaped working face in Yuecheng Mine,and fully summed up the application effect and conditions of this ventilation pattern.%　　随着矿井生产能力的提高，瓦斯问题已成为制约回采工作面生产潜力发挥的重要因素，尤其对于高瓦斯矿井更是如此。对岳城煤矿1301(上)回采工作面双U型两进两回通风方式的应用进行了分析，较为全面地总结出双U型两进两回通风方式的应用效果及应用条件。
