A coalfield is an area of certain uniform characteristics where coal is mined. The criteria for determining the approximate boundary of a coalfield are geographical and cultural, in addition to geological. A coalfield often groups the seams of coal, railroad companies, cultural groups, and watersheds and other geographical considerations.

Stone wrote, "after a thorough and careful examination of the Triassic beds in the Dan River Field the conclusion is reached that there is no reason to expect to find commercially valuable coal beds in this district."
Coal plants have been closing at a fast rate since 2010 (290 plants closed from 2010 to May 2019; this was 40% of the US's coal generating capacity) due to competition from other generating sources, primarily cheaper and cleaner natural gas (a result of the fracking boom), which has replaced so many coal plants that natural gas now accounts for ...
The Scrantons also experimented with anthracite to make steel, rather than charcoal or bituminous coal. [9] The replacement of charcoal with coal in the steel-making process revolutionized the industry, and tied steelmaking to coal-mining areas. In the 1800s, making a ton of steel required a greater weight of coal than iron ore.
