摘要
煤矿采空区瓦斯分为封闭式老采空区瓦斯和开放式现采空区瓦斯,是影响矿井瓦斯涌出量的主要来源,特别是开采工作面采空区瓦斯涌出,是造成瓦斯超限和瓦斯事故的重要因素。采空区瓦斯抽采是有效预防治理瓦斯的措施,许多矿井采用。岳城煤矿1302(上)工作面采用地面钻井法抽采技术治理采空区瓦斯的经验,为有效防治瓦斯提供了新途径。
Goal gas in mines can be divided into two categories： old closed goaf gas and new open goal gas, which is the main reason influencing gas emission, especially the goaf gas emission on mining face. The goal gas emission an is important cause of gas over-limitation and gas accidents. Goal gas drainage is an effective measure to control gas, which has been experience with surface drilling method in 1302 approach for the gas control. used in many mines. By introduction of goal gas drainage mining face in Yuecheng mine, the study provides a new
