Abstract :
[en] Three representative coals from different mines were sampled for analysis. In order to investigate t he effect s of density of samples on t he coal analysis by laser-induced breakdown spectroscopy, the powder samples and pellet samples which pressed with different pressures were selected for the experiment . The spectra of 200～850 nm of powder and pellet coal samples were obtained , and the emission lines of component s such as C , H , O , N , Al , Fe , Ca , Mg , Si , Ti , Na and K were recorded. Emission lines of C , Al , Ca , Mg , Si and Ti element s were chosen for analysis of calibration curve method and internal standardization met hod because of their high intensity and little interference. The results showed that the density of the samples has more effect s on the calibration curve met hod than the internal standardization met hod.
