Evolution of Pore-Fracture Structure and Coupled Damage–Seepage Characteristics of Coal Induced by LCO2 Phase-Transition Treatment: A 3D Digital Core Study
This study combines micro-CT scanning with Avizo-based three-dimensional reconstruction technology to quantitatively characterize the evolution of pore-fracture structures in coal during LCO2 phase-transition treatment and systematically investigates the coupled response of damage evolution and seepage behavior under...
