"Preserving Mine Maps for Future Generations"


The National Mine Map Repository (NMMR) has recently added the capability for the public to search the index of all mine maps in the collection. This new search capability will permit the public and other customers to directly identify mine maps themselves. Additional search capabilities are planned in the future, including the ability to perform a radius spatial search based on a zip code.

The Office of Surface Mining Reclamation and Enforcement (OSMRE), National Mine Map Repository resides in Green Tree, Pennsylvania, and collects and maintains mine map information and images for all types of mining for the entire country, including data and maps specific to the coal fields in the anthracite coal region of northeastern Pennsylvania. The National Mine Map Repository is part of the Technology Services Branch of the Technical Support Division in the Appalachian Regional Office of OSMRE. Some of the customers of the NMMR include: government entities, realtors, land developers, mining companies and homeowners. Many of the maps in the repository are currently available in digital format and the repository is in the process of scanning all the maps in the continually-growing collection. The National Mine Map Repository is always looking for additional mine maps. Please contact us if you have mine maps that you would permit the repository to scan and add to the collection. All physical maps are returned to the owner. Please see our donation page.

You can now search the National Mine Map Repository's Index of Mine Maps Online!!
