Contribución al estudio de la fijación de precios diferentes a las distintas calidades de hullas españolas

[EN] After some brief considerations about the possibility and convenience to settle different prices for the various qualities of coals produced in Spain, a commercial classification into six groups is proposed in the paper, each one defined by the volatile matter and the crucible swelling number. It is made a distribution in the six groups: proposed for the Spanish production of coals on the year 1955, and next, the general lines on which is based a proposed scale of prices for the fines 1-10 mm of the six groups, are also exposed. Starting from the present prices, fixed by the Government and equal for all qualities of coals, it is proposed a series of formulas which give the base prices and premiums for qualities of the different calibrated sizes produced in the provinces of Oviedo, Le6n y Palencia. Finally, these formulas are applied to three different cases.
