Paperback. Condizione: New. Print on Demand. This book presents an analysis of two different coal seams mined in Ohio in the early 20th century: the Pittsburg and Pomeroy seams. The author provides not only a chemical analysis and caloric test of samples of these two seams, but also details regarding the history and geology of each seam. The data demonstrates the wide variation that can be expected within different parts of a given coal seam, such as the presence or absence of partings or rider seams. The author provides historical context for the exploitation of these seams in Ohio, explaining how mining techniques evolved over time and how the coal industry developed in the region. The book concludes by discussing the significance of these seams to the economy and infrastructure of Ohio, highlighting their role in fueling the state's industrial growth.
