【摘要】 本文介绍新疆碱沟煤矿的概况和矿区构造,并且分析了矿区构造演化对其煤层瓦斯的控制作用。碱沟煤矿煤系地层形成后,形成了以七道湾背斜、八道湾向斜和走向逆冲断层及其配套的斜向平移断层为特征的构造形迹。七道湾背斜使煤系地层抬升,以致煤层瓦斯大量逸散;而八道湾向斜则使煤层埋深增加,瓦斯得以封存。碱沟煤矿煤层瓦斯含量与煤层埋深具有比较明显的线性正相关关系。

【Abstract】 The paper introduces the general situation and the structure of Jianggou coal mine,and analyzes the controlling effect of structural evolution to coal mine gas of the mining area.After the formation of coal - bearing strata in Jianggou coal mine,the structural feature marked with Qidaowan Anticline,Badaowan Syncline, and strike thrust faults and inclined strike - slip faults was formed.The Qidaowan Anticline uplifted the coalbearing strata and led to emission of large number of coal mine methane.Badaowan Syncline increased the burial depth of coal seam and made the coal mine methane be storage.Obviously there is a positive correlation between the gas content and the burial depth of coal seam in Jiangou coal mine.
