Richard Sutcliffe invented a conveyor belt in 1905, designed especially for mines. These belts could function in underground areas to transport coal and other minerals. In 1913, conveyors were first used in the manufacturing industry when Henry Ford introduced conveyor belts in the assembly lines of Ford Motor Company.

Coal is transported from the active sections by a belt conveyor system to an underground storage bin. From there, it is transported by belt conveyor to a surface preparation plant where the coal is cleaned, sized, and crushed depending upon the quality. Two exhausting mine fans, located on the surface, ventilate the mine.
