Multivariate statistical techniques have been applied to study interrelationships among 12 variables within a set of 277 coals representing whole-seam channel, column, and core samples obtained from each of the 6 coal provinces of the United States, and varying in rank from lignite through anthracite. The data are maintained in computerized data base at The Pennsylvania State University Coal Research Section. The variables selected are components of the elemental analysis (carbon, oxygen, organic sulfur, hydrogen, and nitrogen), selected components of the proximate analysis (volatile matter and moisture), calorific value, reflectance of vitrinite, and the relative proportions of the 3 maceral groups (total vitrinite, inertinite, and liptinite group macerals). Faactor analyses performed on the entire data set and on subsets separated on the basis of rank, geographic location, and by cluster analysis indicated that rank is the most important factor in determining the amount of variation of each data set. The rank-dependent variables for the entire data set are carbon, reflectance, oxygen, volatile matter, calorific value, and moisture. The maceral groups account for the next greatest source of variation. Organic sulfur is independent of the first 2 factors and is the third most important source of variation. Cluster analyses indicated that the most significant partitioning produces 4 groups which are differentiated primarily on the basis of rank, maceral composition, and organic sulfur content. Factor analyses of the individual groups provide insights into the coalification processes of these more homogeneous coal associations.
