根据实测资料，阳泉五矿综放面走向高抽巷瓦斯抽放量占工作面瓦斯涌出量的９０％左右，抽放浓度平均６０％以上，效果良好，且社会、经济效益十分明显。实践证明，走向高抽巷能有效地解决五矿综放面邻近层瓦斯涌出量大的问题，合理选择走向高抽巷的布置参数及走向高抽巷的抽放负压，可使抽放效果最佳。 According to the measured data, the gas discharge from the fully mechanized top-coal caving face to the fully mechanized top half of Yangquan Mine accounts for about 90% of the gas emission from the working face. The drainage concentration is above 60% on average. The effect is good and the social and economic benefits are obvious. Practice has proved that the move to a high degree of roadway can effectively solve the problem of gas emission in the adjacent layer of Minmetals fully mechanized caving face, the reasonable choice of the layout parameters to the high pumping tunnel and the drainage negative pressure to the high pumping roadway can make the drainage Best effect.
