Mining | National Geographic Society

Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore on ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times. Prehistoric people first mined flint, which was ideal for tools and weapons since it breaks into shards with sharp edges.

Mining and Mineral Use | Earth Science

Underground mining is used to recover ores that are deeper into Earth''s surface. Miners blast and tunnel into rock to gain access to the ores. How underground mining is approached – from above, below, or sideways – depends on the placement of the ore body, its depth, concentration of ore, and the strength of the surrounding rock.

Mining

Most iron ore mining operations use the ''open pit'' method, where miners drill into the rock and blast the ore-bearing material loose with explosives. Huge excavators are then used to gather the loosened ore. To mine metallurgical coal, which will later be turned into coke, it''s usually necessary to sink vertical mine shafts to access coal which is deposited in layers or ''seams ...
