Abstract

Seven coal samples and two anthracite samples are subjected to technical, petrographic, and elementary analysis. The maximum moisture content and total pore volume (for water) in the samples are determined. There is a linear relation between the maximum moisture content and total pore volume. The corresponding correlation coefficient is 0.99, and the coefficient of determination is 98.1%. The relation of the coal porosity with the yield of volatiles and the carbon content in the coal’s organic mass (characterizing its metamorphic stage) is assessed. The corresponding correlation coefficient is 0.86–0.98, while the coefficient of determination is 73.8–95.6%.
