Gas Control Practice and Research of Mechanized Coal Surface in Xuandong No. 2 mine

摘要：

For the U type ventilation of highly gassy mine, mining face gas emission 75 m3 / min above, Ⅲ 3 207 working face of gas in the comprehensive control technology test was researched by XuanDong no.2 mine.Through this implementation for coal seam roof drainage, high gas drainage borehole, to a high smoke lane drainage, lateral high gas drainage pumping lane, low smoke lane of drainage, there are out - coming the suitable method of this ore gas.Putting forward the gas treatment quaternary new ideas, it is extensive popularized significance for the fully mechanized working face of other gas.

关键词： U type ventilation model gas drainage with high level borehole in roof strike high -bleeding roadway horizontal high pumping roadway low smoke lane implementation of drainage
