Encyclopedia > Mined

Mine can refer to a number of things:

  • Mines are tunnels used in mining for extraction of resources.
  • In medieval times, a mine was a tunnel dug under a castle wall to make it collapse. This was known as undermining or sapping. These tunnels were sometimes packed with explosives, leading to its modern military meaning:
  • Mines are stationary self-contained explosive devices used for military purposes:
    • Landmines which are devices placed on the ground to destroy enemy vehicles and kill enemy soldiers who move over them.
    • Naval mines which are devices used for the same puposes as landmines but destroy sea-going vessels.
    • Claymore mines which are military weapons that fire shrapnel and are used for ambush.
    • Pyrotechnical mines which shoot multiple stars cannon style.
  • The word mine is also a possessive pronoun meaning "belonging to me".

In the case of longwall mining of coal, self-advancing roof supports, made of hydraulic jacks and metal plates, are moved ahead, allowing the ceiling in the mined area to cave in as the miners work back towards the tunnel entrance.
In surface mining, the layers of topsoil, or overburden, that were removed in order to reach the mineral are used to fill in the mine and reshape the land.
Like the metal mining industry, the nonmetallic mineral mining industry is influenced by the strength of the industries that use nonmetals in the manufacture of their products; these are industries in which employment is impacted by swings in the economy.
