ABSTRACT:
In a method and apparatus for discriminating a coal species, discriminating values of coal species/properties are prepared corresponding to coal ranks, a coal to be discriminated is irradiated with near-infrared rays having different wavelengths, and light of near-infrared rays reflected from the coal is received; Aborbances of the coal are acquired, and the coal species/property discriminating value of the coal is discriminated on the basis of the absorbances and a prescribed calibration curve.
