依托自行设计加工的含瓦斯煤瓦斯解吸规律实验系统,以煤的瓦斯解吸动力学规律为理论基础,采用模拟测试和理论分析相结合的方法,在等温等压条件下对不同粒度煤样的瓦斯解吸规律进行了模拟测定。通过对实验数据的拟合分析,得出粒度对煤的瓦斯解吸规律的影响,最后对粒度对煤的瓦斯解吸规律的影响进行了理论分析。 Relying on the self-designed experiment system of gas desorption law of coal gas, based on the theory of gas desorption kinetics of coal, a combination of simulation test and theoretical analysis was used to simulate gas desulphurization of coal samples with different particle sizes under the condition of isobaric pressure Desorption laws were measured. Through the fitting analysis of the experimental data, the influence of particle size on gas desorption of coal is obtained. Finally, the effect of particle size on gas desorption of coal is analyzed theoretically.
