Damage constitutive model and experimental study of deep coal rock under thermal-hydro-mechanical coupling

Damage constitutive model and experimental study of deep coal rock under thermal-hydro-mechanical coupling

Abstract This study investigates the thermal-hydro-mechanical (THM) coupled damage behavior of deep coal rocks from the Benxi Formation in the Ordos Basin. By conceptualizing coal rock as a dual-porosity medium comprising fractures and matrix, a damage constitutive model was developed through the in...
