Mining"Mining is the extraction of valuable geological materials and minerals from the Earth and other astronomical objects. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water." - (en.wikipedia.org 01.12.2023) Bergarbeiter Bergarbeitermilieu Bergbaugeschichte Bergmannshammer Bergmannskleidung Bergmannslied Bergmannstracht Bergmännische Kunst Bergschule Brattice Erzgrube Face Froschlampe Förderstrecke Förderung (Bergbau) Gewerke (Bergbau) Grube (Bergbau) Haspel (Bergbau) Kaue Kohlenhobel Level Mine Mining engineer Mining law Mining system Mining technology Mutung Schildausbau Sohlengefälle Underground mine ventilation Wasserlauf (Bergbau) Heavy industry Alaunbergbau Altbergbau Berggrenze Erzbergbau Kohlebergbau Markscheide Mine survey Mining of coal Quarry Quecksilberbergbau Salzbergbau Schieferabbau Sinking Stollenbau Stoping Uranium mining Vorrichtung (Bergbau) Grundstrecke Mine dewatering Schachtförderanlage Shaft Abbauort Mineral extraction Firedamp explosion Mutungsfeld Revierstube (Bergbau)
