| 摘 要： | 在交变电场、声场作用下对煤解吸、吸附瓦斯特性进行了实验研究。得出在交变电场作用下，煤样吸附甲烷的量能很好地遵从Langmuir方程。随交变电场电压增大，吸附常数a变化不大，而吸附常数b却逐渐减小。交变电场的作用减弱了煤的吸附能力和解吸能力，减缓了含甲烷煤的解吸过程。声场的作用使煤的吸附量明显减少，吸附能力降低，且煤的瓦斯吸附量随声强增大而减小。

| Abstract: | The experiment in this case studide the traits of the absorption and desorption of coal to gas in alternating electric field(AEF)or sound field(SF).The research indicates that due to the operation of alternating electric field,the absorbing ability of coal to gas still follows well the rule of Langmuir Equation.In the case,with the field voltage climbing up,absorption constant a changes little while constant b keeps descending.Subjected to the operation of alternating electric field,the absorption and desorption of coal are weakened,and the desorbing process of methane coal is slowed down as well.In addition,the work of sound field lessens the absorbing ability of coal,and the gas absorption of coal minishes as sound intensifies. |
