A confined Pittsburgh seam (DECS-12) coal sample was pressurized with carbon dioxide (CO2) and the changes in sorbed gas concentration matrix properties were studied using dual-energy X-ray computed tomography (X-ray CT). The use of technique enabled quantification spatial temporal variations bulk density effective atomic number. These two quantities used to calculate separately amount reveal kinetics complex heterogeneous processes occurring CO2 injection a consolidated bituminous kept...
Emission monitoring at the facility level (bottom-up, BU) is key for accurate reporting of coal mine methane (CMM) emissions. Recent advances in aerial and satellite observations (top-down, TD) indicate that these methods have potential to support CMM emissions of, as well track effectiveness mitigation actions. That said, studies shown discrepancies between BU TD estimations. Performing with concurrent measurements same mines may help address observed improve quantification narrow gap data....
