Nonlinear Equations of Gas Seepage in Coal Considering Adsorption Effect

摘要

Previous studies showed that gas flowing in coal was nonlinear flow. The paper established the nonlinear equations of gas seepage in coal considering adsorption effect by experimentation with coal seepage properties testing device, which had acquired national invention patent. The effect mechanism adsorption to the gas nonlinear seepage in coal was expounded by analyzing the mechanical characteristics of gas nonlinear seepage. The equation established in the paper could be available for study on gas flow theory and the development of CBM.
