Investigation into the nonlinear damage model of coal containing gas

Safety Science, 2012
By taking the nonlinear deformation properties of coal into consideration, the nonlinear constitutive equation was founded. And in view of the compressible property of gas, the idea of compressive energy of gas was introduced. According to the continuous damage theory and mesoscopic damage theory, it is assumed that the damage variable has a power ...

Fatigue damage evolution of coal under cyclic loading

Arabian Journal of Geosciences, 2018
The experimental study of fatigue damage to coal under cyclic loading is important for guiding the design of pillars in underground coal mines where the pillars may be affected by repeated mining activity. In this paper, the strength, deformation, energy dissipation, and fatigue of samples of coal from a mine in China are studied using cyclic loading ...
