Multifractal Evolution Characteristics of Multiscale Fracture-Pore Structures in Coal under CO2 Phase-Transition Fracturing

Abstract To deeply analyze the multifractal evolutionary characteristics of multiscale fracture-pore structures in coal subjected to CO2 phase transition fracturing (CO2–PTF), CO2–PTF experiments on coal samples were carried out in this study. Multiple multiscale fracture-pore ch...
