Although there were around 1,400 coal mining operations in 26 States in 2005, over two-thirds of all coal mines, and about half of all mine employees, were located in just three States—Kentucky, Pennsylvania, and West Virginia, according to the Energy Information Administration. Other States employing large numbers of coal miners are Alabama, Illinois, Indiana, Virginia, and Wyoming. Metal mining is more prevalent in the West and Southwest, particularly in Arizona, Nevada, and Montana, and iron ore mining in Minnesota and Michigan.
