高瓦斯矿井回采工作面的瓦斯治理

Gas Control on Working Face in Coal Field with High Gas Content

矿井瓦斯涌出、煤与瓦斯突出等问题,是影响煤矿正常生产和威胁矿工人身安全的重大问题。针对天池煤矿首采工作面的瓦斯地质特征,采用了回风巷、瓦斯尾巷联合排放瓦斯和高抽巷抽放瓦斯等综合瓦斯治理技术。分析了天池煤矿首采工作面回采期间瓦斯涌出规律与瓦斯治理效果关系,对天池煤矿深部开采和其他高瓦斯矿井治理瓦斯具有借鉴作用。

The mine gas is one of the major factors that affect the coal mine production safety.Mine gas emission,coal and gas outburst are major problems which affect the normal production and threaten the coal miner′s safety.In view of the gas geological features of first coal mining face in Tianchi coal mine,the authors used integrative gas drainage technology both in return airway and gas tail roadway,and high drainage in high pumping lane.The paper analyzed the gas emission law during recovery on first coal mining face and the effects of gas control.All this provided theoretical guidance and reference for the Tianchi deep coal mining and the gas control of other coal mines with high gas content.
