摘　　要：煤层瓦斯压力是判断煤层瓦斯赋存和瓦斯涌出的基本参数,精准地测定煤层瓦斯压力和含量不仅对钻孔瓦斯抽采具有重要意义,并且对预测煤与瓦斯突出和合理制定瓦斯防治措施也有着重要的作用。现对平煤四矿己15、己16-17煤瓦斯参数进行测定,测定结果可知己15煤瓦斯压力为0. 35 MPa、瓦斯含量为6. 65 m^3/t,己16-17煤层的瓦斯含量为7. 99 m^3/t。Coal seam gas pressure is the basic parameter for judging the occurrence and emission of coal seam gas.Accurate determination of coal seam gas pressure and content is not only of great significance for drilling gas extraction,but also plays an important role in predicting coal and gas outburst and reasonably formulating gas prevention and control measures.The gas parameters ofⅥ15 andⅥ16-17 in Pingdingshan No.4 Coal Mine were obtained by measurement.The results showed that the gas pressure ofⅥ15 coal is 0.35 MPa,the gas content is 6.65 m^3/t,and the gas content ofⅥ16-17 coal seam is 7.99 m^3/t.
