The minecart or mine cart (also known as a mine trolley) is a type of found on a mine railway, used for moving ore and materials procured in the process of traditional mining. Minecarts are seldom used in modern operations, having largely been superseded in underground operations (especially coal mines) by more efficient belt conveyor systems that allow machines such as longwall shearers and continuous miners to operate at their full capacity, and above ground by large dumpers.
Shaped like large, rectangular buckets, minecarts ride on metal tracks and were originally pushed or pulled by men and animals (supplemented later by rope-haulage systems). As mines increased in size and output, the aforementioned methods became impractical because of the distances and quantities of material involved, so larger carts would be used, hauled by narrow gauge diesel and electric locomotives (in coal mining operations, where gas that is flammable would present a problem, the locomotives would be flameproof or battery powered). These were also used to pull trains transporting miners to the workfaces.
Minecarts range in size and usage, and are usually made of steel for hauling ore. Throughout the world, there are different titles for such carts. In South Africa, for instance, a minecart is referred to as a cocopan. In Great Britain, restored mine carts (known as "tubs") containing floral displays can commonly be seen on village greens and outside pubs in former coal mining areas such as Northumberland and County Durham. Mine carts were a very important source of transportation of ore. In Wales, UK, minecarts are known as drams. In the U.S. and elsewhere the term skip is used.
