...-fissures, excludes the pressure-driven Darcian and viscous flow, and ensures gas transport is purely driven by diffusion. Although pulverizing the coal enlarges the surface area for gas adsorption, the increase is only about 0.1 to 0.3 % for coal particles between 40 to 100 mesh (Jones et al., 1988...

... of the earthquakes. Studies regarding the relative amount of energy consumed by fracturing (E G ) is inconclusive, and the disagreement about the relative size of E G is related to the difficulty in assessing the fracture surface area. We conducted a rotary shear experiment under X-ray micro-CT, which allowed...

... in coal mines. In this study, low pressure nitrogen adsorption and high pressure mercury intrusion porosimetry were employed to characterize pore structure of one fireclay and four coal mine shales. The results suggest that the porosity and specific surface area (SSA) for all five samples are dominated...
