摘　　要：采用瓦斯含量法,对狗场煤矿5^#煤层5102回采工作面Ф75 mm顺层钻孔有效排放半径进行了考察。现场实践证明,瓦斯含量法可以用于顺层钻孔排放半径的考察。Investigation was made on the gas drainage radius of Ф75 mm borehole along No.5 seam of5102 working face in Gouchang coal mine by applying the method of gas content. The practice proved that the gas content method can be used for the investigation on the drainage radius of the boreholes along the seam.
