Coal Classification in Terms of the Vitrinite Reflection Coefficient

Resumo

By statistical analysis of research data for coal samples, coal blends, and coal batches used in Russia and Kazakhstan, relations between the vitrinite reflection coefficient and the fuel ratio are established, with good agreement between the calculated and actual vitrinite reflection coefficients. Statistical analysis of a representative database for coal samples, coal blends, and coal batches from Ukraine, Poland, the United States, Canada, and Australia, based on research in those countries, permits the formulation of very close correlations between the vitrinite reflection coefficient and the fuel ratio F_r, with excellent agreement between the calculated and actual vitrinite reflection coefficients.
