摘要
煤层瓦斯含量作为煤层瓦斯基本参数之一,准确测定有重要意义。目前常用的煤层瓦斯含量计算方法是根据已知的煤层瓦斯压力和实验室测出煤样干燥无灰基的吸附常数计算,需水分、灰分系数校正,在实践中我们采用煤样空气干燥基的langmuir体积和langmuir压力来计算煤层吸附瓦斯含量,获得了更为简化适用的公式。
It is important to estimate exactly the gas content, which is one of the basic parameters for coal bed methane. The gas content usually estimate with the gas pressure of coal seam and the adsorption constant on dry ash-free basis, need the correction coefficient of moisture and ash. The Langmuir volume and Langmuir pressure on air dried basis is used to estimate gas content, the formula not only satisfies the works, but also is simple.
