摘要
根据瓦斯赋存及涌出特征,分析了特厚煤层综放工作面的瓦斯涌出规律;结合塔山矿3-5号特厚煤层开采实际,试验了瓦斯治理措施,研究了内错巷抽放瓦斯的特点和效果;得出了顶板内错巷密闭抽放采空区瓦斯的有效方法,使上隅角瓦斯控制在0.3%～0.4%之间,解决了工作面瓦斯超限问题。
According to gas existence and outburst,the gas emission of extra-thick seam was studied.Combined with the real situation of 3-5# extra-thick seam,gas control and prevention measures were tested.The gas drainage characteristics and effect in inboard roadways were analyzed to achieve an effect method to gas drainage in mined-out areas.The gas was controlled ranging from 0.3 to 0.4% in upper-corner angle,which solved the gas gauge.
