Damage characteristics of coal microstructure with liquid CO2 freezing-thawing

Enhanced coalbed methane (ECBM) recovery is significantly affected by the pore structure and cleat network of coal during liquid CO2 (LCO2) injection into unmineable coal seams. However, the changes in the microstructure after coal samples are treated with LCO2 freezing-thawing are poorly understood...
