Unloading deterioration and mechanism of rock under different loading and unloading stress paths

In order to study the failure mechanism of deep coal seam floor under unloading, pseudo-triaxial mechanical tests were carried out under different loading and unloading stress paths. The relationship between rock elastic modulus, generalized Poisson ratio and confining pressure under different stres...
