Coal producers. The largest coal producing countries are not confined to one region - the top five hard coal producers are China, the USA, India, Australia and Indonesia. Much of global coal production is used in the country in which it was produced; only around 15% of hard coal production is destined for the international coal market.
The North Antelope Rochelle coal mine in the Powder River Basin of Wyoming, US, is currently the world's largest coal mine by reserve. The mine was estimated to contain more than 2.3 billion tonnes of recoverable coal as of December 2012. The mine is owned and operated by Peabody Energy.
