Journal ArticleDOI
Evolution of coal permeability from stress-controlled to displacement-controlled swelling conditions
TL;DR: In this paper, a simple free expansion plus push back approach is developed to determine the magnitude of this stress and its effect on coal permeability evolution, which can be used to explain stress-controlled experimental observations.
Journal ArticleDOI
Linking gas-sorption induced changes in coal permeability to directional strains through a modulus reduction ratio
TL;DR: In this article, a model is developed to define the evolution of gas sorption-induced coal permeability anisotropy under the full spectrum of mechanical conditions spanning prescribed in-situ stresses through constrained displacement.
Journal ArticleDOI
Evaluation of stress-controlled coal swelling processes
TL;DR: In this article, a model capable of replicating this apparently anomalous behavior is developed, where the authors consider the interactions of the fractured coal mass where cleats do not create a full separation between adjacent matrix blocks but where solid rock bridges are present.
Journal ArticleDOI
Development of anisotropic permeability during coalbed methane production
TL;DR: In this paper, a general porosity and permeability model was developed to represent the behavior of both the primary medium (coal matrix) and the secondary medium (fractures) under conditions of variable stress.
Journal ArticleDOI
Effect of mining on shear sidewall groundwater inrush hazard caused by seepage instability of the penetrated karst collapse pillar
TL;DR: Wang et al. as mentioned in this paper analyzed the effect of coal mining on groundwater inrush caused by seepage instability of the penetrated karst collapse pillar (PKCP), and a numerical FLAC3D model was conducted to determine the shear stress, damage zone, pore pressure, seepages vectors and effect of damage zone on seepingage field development.
