Abstract
A method for detecting coal quality, including: selecting a plurality of standard coals, acquiring Raman spectral characteristic parameters of each standard coal and characteristic parameters of coal quality components of each standard coal, calculating a mapping relationship between the Raman spectral characteristic parameters and the characteristic parameters of the coal quality components of each standard coal, to establish a relational database of the Raman spectral characteristic parameters and the characteristic parameters of the coal quality components; providing coal to be analyzed, conducting Raman spectroscopy on the coal to yield Raman spectrum of the coal, and performing curve-fitting calculation on the Raman spectrum of the coal to obtain Raman spectral characteristic parameters of the coal; and comparing the Raman spectral characteristic parameters of the coal with the Raman spectral characteristic parameters of the relational database.
