N2 - The 2D geomechanical model of a test on confined adsorption deformation of cylindrical rock specimens and the numerical-analytical method to solve the related boundary problem based on coordinate-wise averaging of a system of equations of poroelasticity for orthotropic media have been developed. It is shown that the axial and radial strains measured in the test are proportional to the volume-average adsorption stresses. Using the test results, the authors formulate and solve the coefficient inverse problem "determination of deformation characteristics and permeability of coal matrix". It is found that the matrix permeability is lower than efficient permeability of a core by three orders of magnitude, which is conditioned by the natural damage structure of coal.
