Pore-Fracture Evolution and Fractal Characteristics of Deep Coal Under Coupled Seepage and Mining-Induced Stress
Clarifying the evolution of pore-fracture structure (PFS) and the associated seepage mechanisms of deep coal under coupled seepage and mining-induced stress is important for the safe and efficient in situ fluidized mining of deep coal resources. In this study, a nuclear magnetic resonance (NMR) online triaxial testing...
