摘要
论述了瓦斯体积分数最低点法测定工作面瓦斯涌出构成的原理。针对某煤矿32212(1)综采工作面的通风技术条件,采用瓦斯体积分数最低点法对工作面瓦斯涌出构成进行了测定。测定结果显示:工作面瓦斯涌出总量为21.36m3/min。其中煤壁瓦斯涌出占总瓦斯涌出量的34.88%,采空区瓦斯涌出占总瓦斯涌出量的47.33%,采落煤瓦斯涌出占总瓦斯涌出量的17.79%。
The principle of measuring gas emission component by the method of the lowest level of gas volume fraction is introduced. Based on the specific conditions of No32212 （1） fully mechanized coal face of a certain Coal mine, the gas emission component is measured by the method of the lowest level of gas volume fraction. The result show： the absolute gas emission rate of this working face is 21.36m3/min, which coal wall gas emission account for 34.88%, coal caving account for 17.79% and goal account for 47.33%.
