This paper presents a theoretical analysis of the damage evolution law of carbonaceous mudstone during compressive failure process under dry–wet cycling. In this study, microscopic testing and uniaxial compression synchronous acoustic emission testing systems are employed to examine the microstructure, mechanical properties, and failure acoustic signal of carbonaceous mudstone. The results demonstrated that dry–wet cycling aggravated the mesostructure damage of carbonaceous mudstone. As the dry–wet cycling increased, the pores of carbonaceou...
