Coal Mining Methods (cont.) Underground mining methods –extracting coal resources from beneath the earth's surface using a series of tunnels or excavations. Coal is extracted using mechanized mining machines and removed, in most cases, via conveyor belts to the surface. The roof (ceiling) and ribs (walls) of the mine are supported (held
North Dakota's first major industry was coal mining. Coal mining and coal plants continue to be important to the state's economy. Though lignite coal presents several problems as a fuel, innovative techniques changed the way coal is used. Coal-fired power plants produce electricity and provide many jobs for North Dakota residents.

There are four other coal mining companies registered with the Coal Authority, including OCCW (House of Water), Ayle Colliery Company, Packaged Water, Three D's Mining, H M Project Developments.
U.S. coal industry employs two mining methods: room and pillar mining and longwall mining. Manual room and pillar mining method was developed and used ever since coal mining began in the 18th century. Mechanized room and pillar mining began in the late 1920s and reached full mechanization in the late 1940s.

The importance of understanding these terms extends beyond industry professionals to investors who need to navigate the complex world of mining …
Coal that is deeper than a few hundred metres under the surface must be extracted using two underground mining methods. Some coal is mined by the Bord and Pillar method. This is where a machine continually cuts into the coal. It tunnels through the coal seams leaving pillars supported by roof bolts to hold up the roof.
