摘 要:为了彻底消除采空区通风的隐患,晋煤集团岳城矿在综采工作面先后尝试大U套小U、二进二回系统、三进一回偏Y型等通风系统,在先期回采工作面采空区瓦斯抽采基础上,提出了回风横川埋管低位抽采、倾斜钻孔中位抽采、高位钻场高位钻孔(定向高位钻孔)的立体式瓦斯抽采模式,并结合地面采空区钻井抽采的措施,形成了四位一体的采空区瓦斯抽采模式,实现采面U型通风。In order to remove the hidden dangers of ventilation in the goaf,Yuecheng Mine,Jincheng Coal Group,has tried several ventilation systems in the fully mechanized mining face,including small U-shaped in large U-shaped system,two-intake-two-return air system,three-intake-one-return air with partial Y-shaped system.On the basis of gas drainage in the goaf of the early mining face,a three-dimensional gas drainage mode is proposed,including the buried pipe low-level extraction of the returning Hengchuan,the medium-level extraction of the inclined drilling,and the high-level drilling of the high-drilling field(oriented high level boreholes).Combined with the drilling and drainage measures in the goaf,a four-in-one gas extraction mode in the goaf is created to realize the U-shaped ventilation in the mining face.
