Mining the Coal. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many U.S. coal beds are very near the ground's surface, and about two-thirds of coal production comes from surface mines.
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.
Refers to the former practice of taking caged canaries into coal mines. The birds would die if methane gas became present and thereby alert miners to the danger. Wildlife in disaster movies assumes the role of the canary in a coal mine, fleeing the scene when catastrophe is imminent.
Coking coal, also known as metallurgical coal, is used to create coke, one of the key irreplaceable inputs for the production of steel. There are many varieties of coal in the world, ranging from brown coal or lignite to anthracite.
This particular mine extracts coal by using a continuous miner, which is also known as room and pillar mining. The equipment cuts a series of paths, or "rooms", leaving sections of uncut coal approximately 20 feet square to support the overhead structure (also known as "pillars").
Drift mine – The simplest method of underground mining, the coal seam is accessed by digging horizontally into the side of a hill. Slope mine – For a shallow underground coal seam, miners dig a slanted or 'sloped' shaft and remove the coal via long convey orbelts.
Coal Mine Safety and Health enforces the Mine Act at all coal mines in the United States. Enforcement activities include: Conducting numerous inspections, including mandatory quarterly inspections of underground coal mines and semiannual inspections of surface coal mines and facilities each year.
The West ia Coal Industry provides about 30,000 direct jobs in WV, including miners, mine contractors, coal preparation plant employees and mine supply companies. Underground mines in 2009 produced 87 million tons with 33 million tons from longwall mining.
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 is a non-renewable fossil fuel that is combusted and used to generate electricity. Mining techniques and combustion are both dangerous to miners and hazardous to the environment; however, coal accounts for about half of the electricity generation in the United States.
The West ia Geological and Economic Survey provides an interactive map of underground and surface coal mining activity in West ia. The map shows areas of active and historical coal mining in both underground and surface mines, with separate colors for auger and highwall mining.

In some cases underground mining also produces enough spoil to require the construction of valley fills. Mountaintop and area mining allows for almost complete recovery of coal seams, and reduces the number of workers required to a fraction of what conventional methods require but produces large volumes of excess spoil disposal needs.
Coal is a fossil fuel and is the altered remains of prehistoric vegetation that originally accumulated in swamps and peat bogs. The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago.
