为了研究煤岩试件中的层理倾角对甲烷吸附-解吸的影响,通过实验室制取层理试件,并通过特制仪器进行室内试验,研究了煤岩试件在甲烷吸附-解吸过程中,层面倾角对其影响规律,得出以下结论:甲烷在吸附-解吸过程中,随煤岩层面倾角增大,层理接触面在试件中的长度、接触面积随之增大,因此吸附、解吸速度增大,吸附量、解吸量增大;煤岩试件吸附瓦斯量对其体积变化有较大影响,吸附量越大,体积应变越大。
In order to study the influence of bedding dip angle on the adsorption and desorption of methane in coal and rock samples, stratified samples were prepared by laboratory and laboratory experiments were carried out by special instruments to study the effect of methane adsorption and desorption , And the influence of bedding angle on it, the following conclusions are drawn: During the process of adsorption-desorption of methane, with the increase of dip of coal bed, the length and contact area of bedding contact surface in specimen increase accordingly, Desorption rate increased, the amount of adsorption and desorption increased; coal sample adsorption amount of gas has a greater impact on its volume change, the greater the adsorption capacity, the greater the volume strain.
