NMR-Based Fractal Characterization of Pore and Fracture Structure Evolution in Coal Under Cyclic Unloading
Understanding the dynamic evolution of pore and fracture structure (PFS) in coal under mining disturbance is essential for safe coal extraction. In this study, coal specimens collected from the Dongqu Mine, Taiyuan, Shanxi Province, China, were subjected to stepwise cyclic confining pressure loading–unloading tests usi...
