Abstract: The present invention relates to a method for detecting moisture and volatile matter content in raw coal using the value of baseline drift, comprising the following steps: selecting a plurality of types of standard coal having different coal ranks and different ash contents, performing a Raman spectroscopy test and a proximate analysis on each type of standard coal, calculating the value of baseline drift in the Raman spectrum, and setting up the mapping relationship between the value of baseline drift in the Raman spectrum and the characteristic parameters of the moisture and the volatile matter content. The same method and reference are used to perform a Raman spectroscopy test on raw coal to be tested, so as to calculate the value of baseline drift in a Raman spectrum of the raw coal to be tested, and obtain the moisture and volatile matter content of the raw coal to be tested.
