摘要
成庄矿为高瓦斯矿井。通过采用"U并U"型通风系统,采空区内瓦斯流向采空区深部,并利用回风巷高位定向钻孔对采空区瓦斯进行抽采。这两种方法相结合,保障工作面采空区和巷道内瓦斯不超限,利于矿井的生产衔接,防止瓦斯事故的发生,实现了矿井瓦斯综合利用。
The ChengZhuang mine is a high gas mine, and has a complex geological structure. The higher gas concentration in the goafs affects the production and safety in mine. By using of the ＂U and U ＂type ventilation system and gas drainage from the high directional drillings in the air return airway of the goafs, we have acquired better results in gas control. It benefits the mine production and convergence and avoids gas accidents. It also promotes the comprehensive utilization of coal mine gas on the other side.
