  • 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.
