A geomechanical model of gas emission from a block-structure coal bed is proposed. The inverse coefficient problem is formulated of finding the initial gas content, diffusion and mass-transfer coefficients by the gage data of the borehole pressure, the solvability of the problem is studied. It is shown that, for the uniqueness of a solution to the inverse problem, additional information is required on the gas-kinetic characteristics of the coal bed.
Keywords: geomechanical model, coal bed, inverse problem, cost function, degassing.
Mots-clés : gas content, diffusion and mass transfer coefficients
