This paper provides an experimental support for increasing the flow conductivity of coal reservoir by identifying permeability change rule caused by reactions with different minerals in coal after injecting carbon dioxide. Based on measurement of nitrogen adsorption, mineral composition and permeability of medium-high rank coal in Tunlan mine and Sihe mine, it is used to investigate the permeability change rule caused by reactions with different minerals in coal and its improving effect after injecting carbon dioxide. A permeability change model was established by making a nonlinear regression analysis of the initial permeability, the reaction time and the improved permeability. The results showed that as a result of CO2-water-rock interact...
