Hempfield Coal Co. opened the Roseytown mines (Hempfield No. 1 and No. 2) in the late 1800s. By 1907, Keystone Coal and Coke Co. had purchased the Roseytown mines and installed a ten-ton Jeffrey mine locomotive. Later, the nearby Crows Nest mine and the Roseytown mine were joined, and miners from the Crows Nest mine entered through the Roseytown portal.
