摘　　要：为了解决石港煤矿综放工作面初采期瓦斯涌出不均匀,严重威胁矿井安全生产的问题,分析了综放工作面初采期瓦斯涌出特征,在15111综放工作面采用伪倾斜后高抽巷抽采初采期瓦斯技术,结果表明:初采期间,基本顶垮落之前,伪倾斜后高抽巷的瓦斯抽采量达到24.58～75.25m3/min,工作面初采期未出现瓦斯涌出峰值,有效地防止了工作面瓦斯超限事故。In order to solve the problem that methane gushing seriously threatens safe mining in full-mechanized caving mining face at preliminary mining period,this paper analyzed methane gushing characteristics.Diagonal high-position methane drainage roadway was applied in 15111 full-mechanized caving mining face.Result showed that before basic roof caved,methane drainage amount reached 24.58~75.25m3/min in high-position roadway at preliminary mining period,which effectively prevented methane disaster.
