摘要
采用HCA-1型高压容量法瓦斯吸附装置,对煤样进行了不同温度下的吸附瓦斯等温线测试,研究了温度对煤的瓦斯吸附常数的影响,并结合物理化学方法,建立了煤的瓦斯吸附常数随温度变化的函数关系。在进行深部矿井瓦斯抽采工程设计中,该研究成果可为煤层气资源评价提供科学依据和理论指导。
The gas adsorption isotherm of coal samples was tested at different temperatures by using HCA- 1 high-pressure capacity gas adsorption device,study was made on the influence of temperature upon the gas adsorption constant of coal,and the function relation of the change of the gas adsorptive constant of coal with temperature by using the physical and chemical method. This research result can provide scientific basis and theoretical guidance for the coal- bed methane resource assessment in the design of gas drainage project of the deep mine.
