The National Mine Map Repository (NMMR)[1] is part of the United States Department of the Interior (DOI), Office of Surface Mining Reclamation and Enforcement (OSMRE or OSM).[2] The NMMR resides in the Pittsburgh suburb of Green Tree, Pennsylvania, and collects and maintains mine map information and images for the entire country, including data and maps of coal mines in the anthracite coal region of northeastern Pennsylvania.[3] The Green Tree facility provides and stores, digitally and in microfilm (aperture cards),[4] over 182,000 maps of abandoned mines. This repository contains maps of mine workings from the 1790s to the present day.[5] It serves as a point of reference for mine maps and other information for both surface and underground mines throughout the United States. It also serves as a location to retrieve mine maps in an emergency. The NMMR provides services ranging from retrieving mine related data for economic analysis to assessing the potential risk associated with underground mining. Through analysis of mine maps and related information, the repository assists private and public sectors in industrial and commercial development, highway construction,[6] and the preservation of public health, safety, and welfare. In addition, they collect, reproduce, and maintain a national inventory of mine maps and supporting documentation for private and public interests.
