Quick answer
The producing mines are four underground mines and 13 surface mines.[1] They produced bituminous coal, and EIA places them in the Appalachia Northern coal supply region.[1] Mines in the county produced 1,891,019 short tons in 2023, so output fell by about 33 percent in 2024.[1]

Surface mining is often used when coal is less than 200 feet underground, and underground mining is used when coal lies deeper.[2] Bituminous coal is the most abundant rank found in the United States, and lignite has the lowest energy content.[3] The coal leases in a 2020 West Virginia Supreme Court of Appeals decision carried a tonnage royalty, a minimum annual royalty and a fixed term of years.[4] Pennsylvania is one of the 24 states with an approved coal regulatory program, so the state is the primary regulator of coal mining there and handles permitting, inspection and enforcement, with oversight from the federal Office of Surface Mining Reclamation and Enforcement.[5]
Anthracite generally has the highest heating value of the ranks, and all U.S. anthracite mines are in northeastern Pennsylvania.[3]
Pennsylvania's Bituminous Mine Subsidence and Land Conservation Act requires an underground mine operator who affects a public or private water supply to restore or replace it.[6]
The Appalachian coal region includes Alabama, eastern Kentucky, Maryland, Ohio, Pennsylvania, Tennessee, Virginia and West Virginia, and underground mines supply most of its coal.[7]
What Buckhead buys depends on the deal, and Buckhead tells the seller up front which interest it is offering to buy — for example, the payments for the rest of the current lease term, a term easement, or a longer-term interest. The coal leases in a 2020 West Virginia Supreme Court of Appeals decision carried a tonnage royalty, a minimum annual royalty and a fixed term of years.[4] Coal rights can also be divided by seam: in one West Virginia case, the leases covered all the coal in all seams above a named seam on the leased tracts.[4]
