Influencing factors of coal bulk density
Abstract：In order to investigate the influence of coal moisture and fineness on bulk density,the variance analysis of moisture ( M) ,medi-um diameter ( d50 ) and distribution parameter ( n) ,which were the important factors influencing coal bulk density were conducted by or-thogonal test. The results showed that the influence of moisture and interaction of medium diameter and distribution parameter was signifi-cant. The lower moisture and wider size distribution helped to improve the coal bulk density. The medium diameter was proportional to the bulk density. Basically,when the M,n,d50 was 5%,0. 5,1. 5 mm respectively,the coal bulk density was the best and the size composition was 75. 69%.
