can cost more to ship it than to mine it. Coal Reserves and Production Coal reserves are beds of coal still in the ground that can be mined. The United States has the world's largest known coal reserves. Depending on consumption rates, the U.S. has enough coal to last nearly 300 years. Coal production is the amount of coal that is mined and sent
electricity and synthetic fuel producers. About 51 percent of South African coal mining is done underground and about 49 percent is produced by open-cast methods. The coal-mining industry is highly concentrated with five companies accounting for 85 percent of saleable coal production. These companies are Ingwe Collieries
"Welcome to the tenth edition of PwC Indonesia's Mining in Indonesia: Investment and Taxation Guide.

outside the mining area for placement and storage. In the Midwest, where the surface topography and coal seams are generally flat, it is common to employ area strip mining in which the fragmented overburden is placed directly by large draglines in the space created where coal has been mined ().In some situations in the eastern United States, a coal seam occurring near the top of mountains is ...
The U.S. coal industry has undergone a remarkable transformation over the last three decades. During this time, coal production has doubled, while the number of active miners has been halved and the number of mines has dropped by a factor of three ().This has resulted in the concentration of production in a smaller number of larger mines.
