The name tag is in mining not like in other parlance for a period (see day ), but for the exposed to the daylight surface.
Day is thus an abbreviation for daylight and the surface exposed to the light of day. In the open pit , these are the exposed to daylight mining areas when trying to near-surface mineral resources to win . Except in the expressions above days (Austrian above days ) and underground , the word is rarely used in this meaning alone, but more often in combinations, for example in underground mining or open pit .
The mining use of the word day can be found colloquially, for example, in the phrase "come to light", which is also used in the standard language as "comes to light".
