A summary and analysis of information concerning the quantity and distribution of coal in the United States. Supersedes Bulletin 1136.

Excerpt from Predicting Coke Stability From Petrographic Analysis of Illinois Coals Previously published curves based on coal petrography and coking data that have been used successfully in predicting the astm stability factor of coke were found to be not generally applicable to Illinois coals. Using Illinois coals or blends containing Illinois and other coals, petrographic analyses and coking data, derived from pilot coke oven tests, provided basic information for modifying these curves. The information is pre sented in this report. The application of petrographic data to the curves for predicting coke stability is demonstrated.
