Modeling pyrolysis of large coal particles with many species... In order to simulate pyrolysis of large coal particles, the Chemical Percolation Devolatilization (CPD) model, which predicts the mass fractions of char, tar and light gas, has been modified and improved....
Influence of a large pillar on the optimum roadway position in an extremely close coal seamBased on the mining practice in an extremely close coal seam, theoretical analysis was conducted on the vertical stressdistribution of the floor strata under a large coal pillar....
Fossil fuel conversion -- measurement and modeling... Results are presented on the devolatilization of large coal particles; transport reactor modeling; fluidized bed model; nitrogen evolution from small and large coal particles; modeling of hydrogen cyanide and ammonia release...
Assessment of unsaturated flow for a large coal mine waste rock pile... To study physical properties and unsaturated flow in rock pile, some soil samples were collected from surface of the large coal waste rock pile and tested for some common geotechnical parameters in the laboratory....
