Mining coal . Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth's surface, while others are deep underground.Modern mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.
Coal Mining. There are two ways to remove coal from the ground: surface mining and underground mining. Surface mining is used when a coal seam is relatively close to the surface, usually within 200 feet. The first step in surface mining is to remove and store the soil and rock covering the coal (called the "overburden").
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.

Coal mining, extraction of coal deposits from the surface of Earth and from underground. Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th
Surface mining also known as strip mining, is the most common type of mining of coal in the world responsible for ∼8% of coal production in China, 80% in Australia, and 67% in the United States . The bed of soil and rock, covering the coal bed (commonly referred as "overburden") is first removed using draglines, power shovels, bulldozers ...
In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the ...

Many U.S. coal beds are very near the ground's surface, and about two-thirds of coal production comes from surface mines. Modern mining methods allow us to easily reach most of our coal reserves. Due to growth in surface mining and improved mining technology, the amount of coal produced by one miner in one hour has more than tripled since 1978.
