Group of stereoview photographs depicting mining operations and coal transportation within the Pennsylvania anthracite coal industry. The images include underground scenes where miners drill and load coal from seams as well as views of ore carts and rail systems used to move coal through tunnels. Additional stereographs show large coal breaker structures near Scranton, Pennsylvania, with steep conveyor tracks rising to elevated processing buildings where coal was sorted and prepared for shipment. Another view documents coal being loaded and transported in wagons beneath heavy industrial structures used in the processing plants. These stereographs were produced by major stereographic publishers including the Keystone View Company as part of educational series illustrating major American industries. The photographs offer a detailed record of the equipment, infrastructure, and labor conditions that characterized the anthracite coal mining industry during its peak years.
