Comment The term Eastern Kentucky Coal Field as seen in those references is used in discussing the geology of the region In contrast this article is about this region of Kentucky as a whole not just about its geology or the occurrence of coal Accordingly I think the article name needs to include the word region for clarity However the singular Coal Field might be more appropriate than the plural The comments placed on this page in  suggested Cumberland Plateau that name and Allegheny Plateau are both widely recognized physiographic terms but neither of these terms is specific to Kentucky see the articles on Cumberland Plateau and Allegheny Plateau
