In 1905, an Irish prospector rotated engineer named Richard Sutcliffe fabricated the very premier underground conveyor belt. This conveyor belt alternated excavation automatically, as it extremely cut down on the labor enforced to get materials from the defending to above ground. Just three years later, engineers invented the roller conveyor.

Belt conveyor systems consist of two or more pulleys (a.k.a. drums). An endless loop of carrying medium—the conveyor belt— rotates about them. To move the belt and the material it carries forward, one or both pulleys are powered. The powered pulley is called "drive pulley," the unpowered one is known as "idler pulley."

A common cause is the conveyor belt. As the coal is being transported from storage to use, the coal-dust begins to fall off the belt and accumulate. Once the dust accumulates to 1/32 of an inch, or about the breadth to leave a footprint, it becomes a fire hazard.
