| 摘 要： | 煤对瓦斯气体的吸附属于物理吸附过程，最终表现为煤表面分子与气体分子间电引力作用过程；通过对施加交变电磁场条件下煤吸附瓦斯物性变化规律的实验研究和机理分析，初步得出了外加交变电磁场可以改变煤对瓦斯气体分子的吸附能力的结论，并据此解释了矿井瓦斯灾害发生过程中的一些实际现象。

| Abstract: | Adsorption of gas by coal is a physical process. In fact, it is attraction between coal surface molecules and gas molecules. The characteristics and mechanism of gas adsorption on coal surface in electromagnetic field are studied both in laboratory and by theoretical analysis. The conclusion is that the alternative electromagnetic field can change the gas adsorption ability of coal and it is used to explain some phenomena of gas hazards. |
