摘要
为了研究温度对煤吸附瓦斯特性的影响对于深部高温瓦斯矿井进行通风设计及煤层气资源评价的指导意义,利用瓦斯吸附装置,对不同煤样进行不同温度下吸附等温线及吸附常数的测定。实验表明:吸附常数b与温度T较好的符合负指数关系;而随着温度的升高,吸附常数a值变化不大,可以认为是某一恒定值。
In order to find the influence of temperature on the coal gas adsorption properties and its important practical significance in guiding ventilation design and assessing coalbed methane resources in deep high-temperature gas mines,the power capacity gas adsorption equipment is done in different temperature conditions on different coal sample. The results show the negative index of the relationship between adsorption constant b and temperature. With the change of temperature, the .adsorption constant a with little change can be considered as a constant value.
