Spatio-temporal evolution of pore and fracture structures in coal induced by initial damage and creep behavior: A real-time NMR-based approach

Spatio-temporal evolution of pore and fracture structures in coal induced by initial damage and creep behavior: A real-time NMR-based approach

Understanding the impact of mining disturbances and creep deformation on the macroscopic deformation and the microscopic pore and fracture structures (MPFS) of coal is paramount for ensuring the secure extraction of coal resources. This study conducts cyclic loading-unloading and creep experiments o...
