With the triaxial servo-controlled seepage equipment for thermo-fluid-solid coupling of gas-containing coal,permeability tests of carbon dioxide in the coal seam under the conditions of different pressures were conducted and the sensitivity of the coal-rock permeability to the stress change response was discussed. The research results showed that the infiltration rate of carbon dioxide increased with the increase of the pore pressure under the conditions of same confining pressure and different axial pressu...
