| Abstract: | Coal methane transports including the coupling process of seepage field,deformation field and stress field in the course of methane developing.According to the theory of fluid-solid interaction mechanics, the author has taken into account the coupling effect of water-gas phase immiscible flow and established the coupled numerical model of unsteady seepage in coal methane unsaturated flow phase. In this nonlinear numerical model, the perturbation and integral transform are adopted. Pore pressure along level distance at different saturation S and time t, and gas phase effect on seepage flow are discussed,some other valueble conclusions have been gotten. 4figs.,6refs. |
