总结了我国在煤中瓦斯解吸放散规律研究领域的进展,提出了研究过程中存在的问题。同时,基于达西定律和菲克定律,分别对球形和圆柱形煤粒瓦斯放散进行数值模拟,并将其与实验数据对比,给出了新的见解和看法。
The progress of study on gas desorption and desorption in coal in China is summarized, and the existing problems in the research process are put forward. At the same time, based on Darcy’s law and Fick’s law, the numerical simulation of spherical and cylindrical coal gas emission is carried out. Compared with the experimental data, new opinions and opinions are given.
