The Mining Basins (also known as the Asturian Mining Basins or the Cuenques Mineres and Cuencas Mineras in Asturian and Spanish) is the name traditionally given to the historical territory located in the Central Coal Basin (Cuenca Hullera Central in Spanish) of the Principality of Asturias. It corresponds to one of the most heavily industrialized areas in Spain, especially linked to coal and ferrous metallurgy.
Although more than 20 Asturian municipalities are officially considered mining councils, in different categories, the municipalities that make up the two regions most directly linked to coal and which have had the greatest historical importance in economic, social and cultural matters are popularly referred to as mining councils, such as Caudal Valley (Mieres, Lena, Aller, Ribera de Arriba, Morcín and Riosa) and Nalón Valley (Langreo, San Martín del Rey Aurelio and Laviana).
