摘　　要： 以卧龙湖10煤为研究对象,分别采用钻孔实测含量、井下测试含量、间接法和涌出量反演法测定煤层的瓦斯含量,并将其进行对比分析。结果表明:井下测试含量普遍大于根据瓦斯压力间接计算得到的瓦斯含量,井下测试含量为间接法计算含量的1.115倍;井下测试含量与反演瓦斯含量差值较小,实测瓦斯含量为反演瓦斯含量的1.077倍;井下测试含量明显大于钻孔测试瓦斯含量,井下测试含量为钻孔测试含量的4.038 2倍。 The borehole gas desorption method, direct method, indirect method and the method of reversely calculate gas content with gas effusion amount are used to determine gas content of No. 10 coal seam in Wolonghu field. All of the results are contrasted, it shows that the result of direct method is general more than the result of indirect method which is 1.115 times than indirect method, and is similar to the result of gas effusion inverting method which is only 1.077 times than the later. The result of direct method is remarkable more than the result of desorption method, it is 4.0382 times than the result of the borehole gas desorption method.
