Influence of Ambient Humidity on the Creep Properties of Rock Masses and Establishment of a Creep Damage Constitutive Model

Abstract

Abstract To investigate the effects of high humidity on the instantaneous and creep mechanical properties of deep mine pillars, in this study, presandstone samples are subjected to a controlled high-humidity environment in a custom-built simulation ... Practical Applications In deep mineral resource extraction, mine environments frequently exhibit high humidity levels exceeding 80%. This condition significantly compromises the mechanical properties of rock pillars (e.g., sandstone pillars) supporting ... Graphical Abstract The flowchart begins with two images labeled High humidity of the environment of roadway and Water vapor erosion of rock pillar induced disaster. Arrows from the images point to a central 'Water-Rock Interaction' cloud, which branches ...
