Controversy: Mechanical fatigue or hardening of rocks after their excavation
Abstract It is pointed out that strength value of rock samples changes with time after sample excavation from a quarry. Three main stages of strength variability with time are distinguished: 1-the stage of hardening connected with increase in the compression strength; 2-stage of equilibrium of the antagonistic processes: hardening and mechanical fatigue; 3-stage of manifestation of mechanical fatigue. Mechanical fatigue is favorable to the manifestation latent weakness surface to new crack formation and at last to total disintegration in rock samples.
