Parc Nantgarw The deepest mine in south Wales. Nantgarw Colliery was one of the flagships of the National Coal Board. It was the nearest deep mine to Cardiff, and a reminder to travellers that they had entered the south Wales coalfield. Opened in 1911, it boasted two large shafts and, at a depth of 782.73m (856 yards), was the deepest mine in south Wales. However, despite appearing as a fine example of a clean and efficient modern coal industry, the colliery was abandoned in 1927 due to lack of manpower, poor industrial relations and, above all, being located above very complex underground geology.

Tagebau Hambach A coal mine in Frameries, Belgium. 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.

- I doubt the Hull Rust mine is the largest open pit mine in the world, as it can't be much larger than 25 square km (being 8km long and just over 3km wide). The lignite open pit mines in Germany are larger. Garzweiler is currently about 48 square km, and Hambach is 33 square km.

- Further to Dave Haynes' reply, the deepest penetrations have been by boreholes, not mines. There is a 9.1km borehole in Germany, part of the Continental Deep Drilling Project (KTB), but deeper still is the 12.25km Superdeep hole in the Kola Peninsula near the Arctic Circle in Russia, drilled between 1977 and 1989. The latter is roughly 0.4% of the distance (2,900km) to the core of the earth.

- The rank of a deposit of coal depends on the pressure and. heat acting on the plant debris as it sank deeper and deeper over millions of years. For the. most part, the higher ranks of coal contain more heat-producing energy. Lignite is the lowest rank of coal with the lowest energy content. Lignite coal deposits.

Coal mining There are six principal methods of underground mining: 1  Longwall mining accounts for about 50 percent of underground production. The longwall shearer has a face of 1,000 feet (300 m) or more. It is a sophisticated machine with a rotating drum that moves mechanically back and forth across a wide coal seam.

Where is Coal Found? A third of the coal is mined in the Appalachian Coal Region where the larger mines are underground and the smaller ones are surface mining. West Virginia produces the most coal for this region and is the second largest coal producing state in the country.eeper coal beds can be found up to one thousand feet below the earth. Miners tunnel underground to get this coal. This is the most dangerous kind of coal mining. If a mine shaft collapses, miners can become trapped and miners are at risk to develop black lung disease after a career of breathing the coal dust.

Coal Some coal beds lie within 200 feet of the earth’s surface. These beds are mined by stripping the top soil off the coal. Then the coal is dug out. This is called surface mining. Deeper coal beds can be found up to 1,000 feet/305 meters below the earth.

Hydrothermal vent These black smokers are of interest as they are in a more stable area of the Earth's crust, where tectonic forces are less and consequently fields of hydrothermal vents are less common. The world's deepest known black smokers are located in the Cayman Trough, 5,000 m (3.1 miles) below the ocean's surface.
