Etymology

Origin of mine1

First recorded before 900; Middle English; Old English mīn; cognate with Old Norse mīn, German mein, Gothic meina; see origin at my, me

Origin of mine2

First recorded in 1275–1325; 1875–80 mine 2 for def. 5; (for the verb) Middle English minen, from Old French miner (cognate with Provençal, Spanish minar, Italian minare ), from Vulgar Latin mīnāre (unrecorded), probably from a Celtic base akin to Middle Irish méin, Welsh mwyn “ore, mineral”; (for the noun) Middle English from Middle French, perhaps noun derivative of miner “to mine” (compare Medieval Latin mina “mine, mineral”)

Explanation

A mine is a hole in the earth from which workers take valuable things: coal, diamonds, copper. It is also a bomb that explodes when it's touched, often buried in the earth. When you think of mines, think of something beneath the surface or hidden. People mine for gold by sifting through water and rocks. West Virginia is famous for its coal mines. A mine field might describe a field laced with explosives — such as landmines. When people put these explosives in place, they're mining the land. Also, any dangerous situation can be called a mine field. Talking about sensitive subjects — like religion or race — is a verbal mine field for sure.
