摘要
某煤矿201工作面的相对瓦斯涌出量达到10.8m^3/t,工作面的绝对瓦斯涌出量达到58.97m^3/min为高瓦斯工作面。为有效的抽采工作面的瓦斯确保安全生产,采用FLUENT数值模拟、现场试验确定预抽钻孔的间距为5m,有效抽放半径为2.5m。
The relative gas emission of 201 working face of a coal mine is 10.8m^3/t,and the absolute gas emission of working face is 58.97m^3/min.In order to effectively extract the gas in the working face to ensure the safety of production,fluent numerical simulation and field test are used to determine that the spacing of pre drainage boreholes is 5m and the effective drainage radius is 2.5m.
