- Title
Mathematical modeling of methane flow in coal beds.

- Abstract
The paper offers to describe the free and occlude gas filtration and diffusion in a coal bed by a numerical model in the form of a system of heterogenous parabolic equations. The gas flow as a shock and depression wave has been considered, and the desorption isotherm conditions for these waves to arise in a coal bed are formulated. By analyzing experimental data on cavities generated by a sudden coal and gas outburst, the authors construct the numerical model describing gas and coal mix outflow in a mine.
