The history of coal mining in the United States goes back to the 1300s, when the Hopi Indians used coal. [citation needed] The first commercial use came in 1701, within the Manakin-Sabot area of Richmond, ia.Coal was the dominant power source in the United States in the late 1800s and early 1900s, and although in rapid decline it remains a significant source of energy in 2019.
Other underground coal mines are laid out in a checkerboard of rooms and pillars (Fig. 2), and the mining operation involves cyclical, step by-step mining sequences. The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal (generally 40 to 80 feet on a side) left to support the mine roof.

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
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 choice of mining method largely depends on the geology of the coal deposit. Underground mining currently accounts for a bigger share of world coal production than opencast; although in several important coal producing countries surface mining is more common.

Coal production leads the Indian mining industry, accounting for 78 percent of total mineral sector production. India's coal reserve is estimated at 301.5 billion tons (10 percent of global reserves). India's demand for coal continues to increase to meet the needs of coal .
Coal production in China has increased by 102%, from 1.38 billion tons in 2001 to 2.79 billion tons in 2008, but the number of coal mines has been reduced by 50%. This implies that coal mining activity is be- coming more intensive and the environmental effects are becoming more prominent problems.
India has emerged as the third largest coal producer in the world after China and USA with a 9% share of the total global coal production. While the coal production from underground mining in countries like China, USA and Australia are about 95, 33 and 20% respectively, India produces only about 15% of coal from underground mines (Prasad 2009).
Global demand for machinery used in metals and minerals mining applications is projected to climb more than 5% annually during the 2017-2022 period, while sales of coal mining equipment are expected to grow just 2% per year because of a worldwide shift toward the use of natural gas and alternative fuels.
