摘要
根据矿井高瓦斯的煤层特征,通过分析矿井瓦斯来源的构成情况,针对其2个工作面采用的不同采煤方法,分别提出埋管抽采、高位巷抽采、高位钻孔抽采等抽采设计,应用于不同的回采工作面,并通过监测瓦斯涌出量和风排瓦斯浓度的变化,确定出该瓦斯抽采方案合理可行。
According coal seam characters of highly gas coal mine , coal mine gas sources constitute was analyzed, to different coalmining method of two working face, and then pipe laying gas extraction, high level roadway extraction, high level drilling extractionand so on were put forward, respectively, and these were applied in different working face, and then according gas emission monito-ring and gas density variation by ventilation, the gas extraction scheme was confirmed reasonable.
