Damage evolution and failure mechanisms under unloading tests of coal based on mining and excavation processes
To investigate the damage characteristics and strength attenuation characteristics of coal, true triaxial single-side and double-side unloading tests of coal under various in-situ stresses were designed and conducted based on actual mining processes. The results indicated that within the depth range...
