N2 - The thermophysical properties of virgin and heat-treated Pittsburgh seam coal were determined as part of a comprehensive study of the combustion of monolithic coal block. The information was sought primarily to assist in the characterization of pyrolysis and combustion processes in underground coal-mine fires. It should also prove to be useful in the study of in situ and surface coal gasifiers, and contribute to the establishment of reliable data for the properties of some particular coals. Measured properties include thermal conductivity, specific heat, thrmal expansion, and density. The transport-property data were obtained (when feasible) carbonized for five hours at temperatures of 350 degree C, 475 degree C, 500 degree C, 650 degree C, and 850 degree C. Although shape trends and interdependence among all properties were evident from the results, only a limited number of correlative relationships could be developed, primarily because of the inhomogeneity of coal materials by specimen variation.
