Mining

Mining is the process of extracting resources, usually mineral resources from objects like planets and asteroids. Mining operations were an important part of the economy of civilizations throughout the galaxy. ''

Earth and the Terran Federation
The American town of Carbon Creek operated a mine in the 1950s. At some point a mine shaft was constructed near the Presidio in San Francisco.

By 2014 humans had begun to mine the sea floor on Earth.

The Terran Federation began operating small and large mining colonies such as the Artemis Mining Colony, established in 2048 Artemis Johnson. Often these facilities would not have artificial gravity, as it was not practical. Also, mining operations on Rhea discovered some of the richest deposits of many sought-after ores in all of the federation, including Uranium, Sirium, Platinum and Pergium.

Sulfur mines exist on the moon of Io.

After the war, C-29 Combat Androids were reconfigured to work in mine shafts.
