Surface mines (sometimes called strip mines) were the source of about 63% of the coal mined in the United States in 2018. These mining operations remove the soil and rock above coal deposits, or seams. The largest surface mines in the United States are in Wyoming ...

Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.

The dominant minerals are sphalerite (zinc sulfide), silver-rich galena (lead sulfide), pyrite (iron sulfide), and marcasite (iron sulfide). Red Dog is one of the largest zinc deposits in the world. Mining of lead and zinc began in 1990 and continues today; the Lik and Drenchwater deposits have not been mined.

Sphalerite has been produced from this district since the 1860's. Prior to that, galena and smithsonite were the dominant minerals produced. Hundreds of mines producing sphalerite are known. All of the mines are currently inactive and most are inaccessible or difficult to find because they have been overgrown, collapsed, filled-in or leveled.

Pyrite and Coal Mining. Sulfur occurs in coal in three different forms: 1) organic sulfur, 2) sulfate minerals, and 3) sulfide minerals (mostly pyrite with minor amounts of marcasite). When the coal is burned, these forms of sulfur are converted into sulfur dioxide gas and contribute to air pollution and acid rain unless they are removed from the emissions.
