The next major innovation was the underground conveyor belt, which mining engineer Richard Sutcliffe invented and patented in 1905. While conveyor belts already had applications in the mining industry, they weren't yet used underground. They needed some adaptations to survive the harsh environments and operate in confined spaces.
