Experimental study on porosity and permeability characteristics of damaged coal in different shear end faces and confining pressures
Coal damage is a significant factor which affects coal permeability changes and gas flow. Damage-based seepage testing system with multi-shear end faces and nuclear magnetic resonance instrument were adopted to analyze porosity and permeability characteristics of damaged coal in different shear end...
