Eight stereoviews published by Keystone View Company document anthracite and soft coal mining operations in Pennsylvania, primarily around Scranton and Ashley. The cards are mounted on standard gray Keystone stock with printed series numbers and captions visible along the lower borders and side margins. Subjects include underground mine interiors, coal breaker exteriors, and industrial machinery photographed in the late nineteenth to early twentieth century.

Captions identify specific operations: knocking down, breaking, and loading coal at an anthracite mine in Scranton; loading cages with cars of coal at the bottom of a shaft; a hoisted car of coal over the shaft at the head of a breaker ready to be dumped; a tandem automatic slate picker in Scranton; a close-cut in a soft coal mine in Pennsylvania; a coal breaker exterior with a steep trestle incline; and shipping coal with a coal breaker visible in the background at Ashley, Pennsylvania. Railroad cars stenciled 489 41 appear prominently in the Ashley shipping view alongside loaded coal beds in the foreground.

Keystone View Company, founded in Meadville, Pennsylvania in 1892, produced one of the most extensive commercial stereoview series in American history, with their educational mining sets widely distributed to schools and institutions. Underground views in this group capture miners in work clothing holding tools beside coal-laden rail cars within timber-shored passages, while exterior views convey the imposing scale of late industrial-era breaker architecture.

Series numbers visible on select mounts include 77, 79, and 82, with additional catalog numbers printed in the lower caption strips of each card.
