Explore the science and value of Ohio’s coal seams.
This two-part bulletin surveys the Monongahela Formation’s upper productive coal measures and the four Allegheny seams—Clarion, Lower Kittanning, Middle Kittanning, and Upper Freeport—with detailed chemical analyses and calorific tests. Written by J. A. Bownocker with chemistry input from N. W. Lord and E. E. Somermeier, the work explains how coal quality affects its fuel value and practical uses, including washing and testing methods.
- Learn how coal samples are analyzed, how moisture and other constituents impact heating value, and how results are reported.
- See the practical implications for coking, fuel efficiency, and mining decisions across Ohio’s coal fields.
- Understand the evolution of sampling and testing techniques and what they mean for interpreting data.
Ideal for readers of coal geology, energy resources, and historical engineering studies, this edition provides a clear, data-driven look at coal quality and its applications.
