    Miner Wikipedia

    A miner is a person who extracts ore, coal, or other mineral from the earth through mining.There are two senses in which the term is used. In its narrowest sense, a miner is someone who works at the rock face; cutting, blasting, or otherwise working and removing the rock. In a broader sense, a "miner" is anyone working within a mine, not just a worker at the rock face.
