Abstract
Methods and apparatus for determining a property of bulk coal from a fluorescence spectrum of the coal are disclosed. In the methods the coal is illuminated so that a plurality of macerals at the surface of the coal are illuminated with UV light. Intensities of fluorescent light from the coal are determined as a function of wavelength and output signals related to the intensities are derived as a function of wavelength. A property of the bulk coal is then determined by:
