The Outburst can be defined as a sudden release of coal and rock accompanied by large quantities of gas into the underground coal mine workings which represents a major hazard in underground coal mines. Gas drainage has been proven to be successful in reducing outburst hazards by decreasing the in-situ gas pressure. One of aspect of gas drainage from coal seams is coal matrix volume changes. Cu...
Phase diagrams of carbon dioxide, nitrogen and their mixtures with different amounts of nitrogen (e.g. 5 mol%, 10 mol% N2) were calculated with high accuracy with the NIST Reference Fluid Thermodynamic and Transport Properties database program REFPROP® for up to 200 bar, as well as density-pressure diagrams. Beside the use of carbon dioxide as a solvent for supercritical fluid extraction, incre...
