摘　　要：对煤粒瓦斯解吸的各种经验公式进行了综述分析,探讨了其间的内在联系,并进行了对比分析。选取不同粒度煤样在空气中进行瓦斯解吸实验,用不同的经验公式对实验数据进行拟合,指出了描述不同粒度下瓦斯解吸的最佳经验公式,这为计算瓦斯含量、瓦斯涌出量提供了依据,对进一步研究瓦斯解吸规律具有参考意义。This paper summarized various kinds of empirical formulas for gas desorption of coal particles,discussed their inner relationship and carried out the comparative analysis. Coal samples with different particle size were selected for gas desorption experiment in the air,different empirical formulas were used to fit in the experimental data,and the best empirical formulas for expressing gas desorption of coal samples with different particle size were proposed,all of these provided basis for the calculation of gas content and gas emission and was of great reference significance to the further research of the gas desorption laws.
