Mechanical properties and fracture damage law of coal-rock composition under the action of supercritical CO2

Mechanical properties and fracture damage law of coal-rock composition under the action of supercritical CO2

The injection of CO2 into deep unrecoverable coal seams is one of the effective ways to achieve CO2 geological sequestration, but CO2 will be in a supercritical state under the action of high pressure and high temperature. In order to investigate the effect of supercritical CO2 action on coal reserv...
