Group of 10 stereoviews illustrating coal breaker operations and the industrial infrastructure of the Pennsylvania anthracite region. The views include large coal breaker buildings with steep conveyor structures used to raise raw coal from mine shafts before sorting and processing.

Several stereographs depict interior processing areas where coal was transported along mechanical conveyors and sorting systems. Other images show miners working underground with drills and hand tools while breaking and loading coal from the mine face.

Published primarily by the Keystone View Company, these images were part of widely circulated stereographic educational series documenting American industry. The photographs provide a detailed visual account of the mechanical systems and labor practices involved in coal production during the height of the anthracite mining era.
