摘要
煤体变形存在于煤层气开采的整个过程中,其对气体的吸附/解吸有着重要的影响,它们之间的关系更是影响到煤层气的产量。采用分子模拟软件Materials Studio(MS)对赵庄3#煤模型进行了不同应变下CH4的等温吸附分子模拟,根据模拟结果给出了煤体变形与CH4吸附/解吸量之间的关系式,并对此关系式进行了误差分析,结果表明此关系式能够满足工程要求。
Coal deformation exists in the whole process of coalbed methane mining,which has an important influence on gas adsorption and desorption.The relationship between coal deformation and gas adsorption and desorption affects the production of coalbed methane.Molecular simulation software,Materials Studio(MS),was used to simulate the isotherm adsorption of CH4 under different strains of Zhaozhuang 3#coal model.According to the simulation results,the relationship between coal deformation and CH4 adsorption and desorption was given.An error analysis of this relationship was carried out.The results show that this relationship can meet the engineering requirements.
