Fracture Propagation and Fatigue Damage Evolution in Rocks Under Cyclic High-Pressure Gas Impacts
Cyclic high-pressure gas impact is a promising waterless stimulation method for enhancing permeability in deep low-permeability coal seams. However, the nonlinear fracture evolution, cumulative fatigue damage, and coupled fracturing mechanisms during repeated gas impacts remain insufficiently understood. In this study,...
