mine: English has two quite distinct words mine. The first person possessive pronoun [OE] goes back to a prehistoric Germanic *mīnaz (source also of German mein, Dutch mijn, and Swedish and Danish min), which was derived from the same Indo-European source as produced English me. Originally it was an adjective, but in the 13th century the -n was dropped before consonants, and eventually the resulting my took over the adjective slot altogether, leaving mine as a pronoun only. Mine ‘excavation’ [14] is of uncertain origin.

It comes via Old French from an assumed Vulgar Latin *mina, which may go back ultimately to a Celtic *meini- ‘ore’ (Gaelic has mein ‘ore, mine’ and Welsh mwyn ‘ore’). The use of the word for an ‘explosive device’, which dates from the 17th century, arose from the practice of digging tunnels or ‘mines’ beneath enemy positions and then blowing them up.

mine (n.1)youdaoicibaDictYouDict
"pit or tunnel in the earth for obtaining metals and minerals," c. 1300, from Old French mine "vein, lode; tunnel, shaft; mineral ore; mine" (for coal, tin, etc,), of uncertain origin, probably from a Celtic source (compare Welsh mwyn, Irish mein "ore, mine"), from Old Celtic *meini-. Italy and Greece were relatively poor in minerals, thus they did not contribute a word for this to English, but there was extensive mining from an early date in Celtic lands (Cornwall, etc.). From c. 1400 as "a tunnel under fortifications to overthrow them."
