Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production.
Coal mining regions are significant resource extraction industries in many parts of the world. They provide a large amount of the fossil fuel energy in the world economy.. The People's Republic of China is the largest producer of coal in the world, while the United States contains the world's largest 'recoverable' coal reserves (followed by Pakistan, Russia, China, and India).
