Conventional mining employs crews of miners who use explosives and drills to extract coal, which is then loaded onto cars for transport to the surface. This method presents higher risks to miners because of the explosives. The coal dust generated by the drilling and explosives is also a health hazard when continuously inhaled.
The continuous miner, a machine that extracted coal and loaded it as well, eventually replaced loading machines. At the turn of the 21st century, Joy loaders were still being used in three Consol Energy mines and one Eastern-Peabody mine in northern West Virginia.
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. At first, machines helped miners load more coal; eventually, they put the majority of miners out of work.
Scrapers are used in coal mines for cutting and transporting weathered sandstone as well as coal. The coal excavated by it is however smaller in size. A Scraper may take 5 to 6 minutes for a complete cycle of loading and unloading if the total up-and-down distance of a trip is nearly 300 m.
