Influence of supercritical CO2 saturation on the failure process of hot dry rock with acoustic emission monitoring

To investigate the effect of supercritical CO2 saturation on acoustic emission (AE) signal properties in hot dry rock failure process, AE tests were conducted on granite under uniaxial compression. The results revealed that the strength of granite was obviously decreased after supercritical CO2 satu...
