摘要：
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 irradiated with near-infrared rays having different wavelengths and light of near-infrared rays reflected from the coal is received; absorbances of the coal are acquired; and the coal species/property discriminating value of the coal is discriminated on the basis of said absorbances and a prescribed calibration curve.
