2016-6-15 The rank of the coal refers to the degree of oetamorphism undergone by a coal seam due to time, temperature or pressure. In South Africa, the influence of rank has not yet been quantified in relation to the mechanical properties of coal. This is due largely to the methods used in the northern hemisphere being unsuitable for South African coals.
