| 摘 要： | 对不同变质程度煤瓦斯吸附常数a、b值的电磁效应进行了实验研究．研究表明，正弦波电磁场作用对吸附常数a值影响不大，可以明显的减小吸附常数b值．吸附常数b值随电磁场频率的增高成负指数幂减小，随电磁场电压的升高成线形减小．外加电磁场作用可以降低煤对瓦斯的吸附能力和吸附量．

| Abstract: | The experimental in the effects of electromagnetic fields on gas adsorptive a/b of different coal rank was carried out. The results show that the sine wave electromagnetic fields almost have no effects on gas adsorptive constant a, but it can make adsorptive constant b reduce obviously. Adsorptive constant b decreases with voltage and frequency of electromagnetic field as minus exponent. Adsorptive constant b linearly decrease with voltage of electromagnetic field. The adsorption of gas by coal and gas adsorptive volume can be reduced by electromagnetic fields. |
