The authers made an experiment about the relation between the ignition temperature and the friability of coals as expressed by the so called “Average particle size”.<BR>The results of this experiment are as follows:-<BR>1) When the coal is crushed by compressive load, the Rosin-Rammler's function is applicable to thedistribution of its products. Accordingly, we can calculate the “Average particle size” of the products.<BR>2) We can not recognize the fixed correlation between the ignition temperature and the friability of coals.<BR>3) Taking Joban coals as an example, the coals from different parts of the same coal-seam have not always a fixed correlation between the ignition temperature and the friability.
