A Basic Introduction to Underground Mining | Crypto Blog Group

 · Underground mining is more expensive than surface mining and can be dangerous. This kind of mining is only used in areas where quality ore, such as gold, are concentrated in thin veins and other remarkably rich deposits. Underground mines can also be excavated underwater, which is a significant advantage over surface mines.
