摘　　要：为了深入分析温度对煤体瓦斯吸附特性的影响,利用自行研制的煤层气高压吸附装置,开展不同温度条件下的含瓦斯煤体吸附试验。试验结果显示:吸附压力对煤体吸附性能的影响具有明显的阶段性;吸附常数a随着温度的增加呈现出先增大后减小的变化特征,具有明显的阶段性;吸附常数b值随温度的增加逐渐降低,但降低幅度逐渐变缓,并最终趋于恒定。In order to analyze temperature on influence adsorption properties of coal containing gas, coalbed methane high pressure adsorption apparatus was used by self-developed, and tests of coal containing gas adsorption was carried developed under different temperature conditions. Experimental results show that： the effect of pressure on coal adsorption properties had the obvious stages. In the temperature increase process, adsorption constant a showed the obvious stages that it was trend of first increase and then decrease. Adsorption constant b value decreased with increasing temperature, but the reduction had slowed clown significantly, eventually reaching a plateau.
