Damage effect of coalbed methane transport on coal strength

2022
During coalbed methane mining, the gas pressure interactions within the matrix- fracture cause damage effects in the coal seam, resulting in a reduction on the strength of the coal. To investigate the damage effect of the coal strength, a conceptual model of matrix and fracture geometry deformation was proposed, and then, a permeability model with ...
