Outline
In the article, it is discussed the effects of drying time, prepared sizes, preparation time, stirring means and storage time of samples on measurement results of caking index which are not specified in the national standard GB/T 5447—2014. Such two types of frequently-used bitumite, coking coal and gas coal are selected for experimental study. The study results showed that the effects of drying time, particle size and preparation time of samples on measurement results of G value were the most significant, the effects of analysis link and storage time of samples on measurement results of G value took second place, while the effects of stirring means on measurement results of G value were minimum. The specified control conditions of related influencing factors are given through experiments so as to achieve the goal of improving the accuracy of measurement results for caking index of bitumite.
