There coal samples with different ash-contents producing explosions under standard condition of temperature and pressure of Godbert’s apparatus were chosen for the study. The ash-contents and the bulk densities of each of the different range of particle-sizes were determined. The results obtained reveal that the bulk density increase with the increase of the ahs –content of all the three samples. The three empirical equations derived for each of the samples may be employed to evaluate the value of bulk density of any of them at any arbitrary value of the ash-content lying within the range of observation. The nature of variation of one parameter with respect to the other for all the three samples can be examined from the graphs.
