The Mines Today. From the days of the salt industry until the 1940s, most coal was loaded using hand tools like picks and shovels. Machines were introduced gradually during the early 1900s, allowing miners to load more coal in less time. Mechanization began with undercutting machines around 1900 and advanced to loading machines in the 1920s.
