摘要

The mathematical model and the numerical simulation for the transfer of coal-bed methane were established based on the combination of the porous flow theory and elastic-plastic mechanics theory and the numerical solution was given, together with the consideration of the fluid-solid interaction between the coal-bed gas and coal framework. Then the dispersion for the equation of gas porous flow and coal seam distortion was carried out and the functional analysis equation was obtained. Finally, the coupling solution was educed and calculated by finite element method(FEM) on a model example.
