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.

In room-and-pillar mining, coal deposits are mined by cutting a network of 'rooms' into the coal seam and leaving behind 'pillars' of coal to support the roof of the mine. These pillars can be up to 40% of the total coal in the seam - although this coal can sometimes be recovered at a later stage. Longwall. When is this method used?
