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.
In 1982 the responsibility of maintaining the repository and its staff was formally transferred to DOI's Office of Surface Mining Reclamation and Enforcement. Later, when BOM was dissolved in 1996, all of the maps from the BOM offices were consolidated into the current OSMRE Pittsburgh repository. The Wilkes-Barre repository was closed in 2011,[9] and its collection transferred to the Pittsburgh office,[10] which is designated as the National Mine Map Repository.
The mission of the repository has always been to obtain authoritative maps on past and current mining operations and preserve them on microfilm. Higher priority is given to maps of mines in areas where the potential for adverse impact to the environment is more significant. The NMMR, in addition to being an archival entity concerned with the preservation of mine maps, is also a basic reference file of information on mines. The information is made available to federal and state geological surveys, state mining bureaus, mining companies, oil and gas companies, conservationists, research and planning organizations, water pollution boards, city and industrial planners, highway engineers, building contractors, real estate developers and private citizens.
Today the NMMR facility is equipped with modern map scanning and archiving capability to digitize maps. The primary archival method remains microfilm although the repository's holdings are increasingly available in digital format.
The NMMR contains digital and microfilm maps of surface and underground coal, metal, and non-metal mines throughout the United States. Some of the information that can be obtained from the repository includes:
The NMMR acquires maps through public outreach directed at state and federal environmental agencies as well as mining companies, engineering and consulting firms, surveying companies, universities, and private citizens. The repository is constantly seeking donations of mine maps to add to the microfilm/digital collection.[12]
When maps are received from a donor, they are scanned and stored in both microfilm and digital archives. The maps, along with a scanned images (upon request), are returned to the donor. The repository does not retain hard copies of maps.
Procedures
As maps are obtained at the repository, they are assigned a unique six-digit identification number (document number). Data sheets are prepared for each map giving all available information including: map document number; state; county; mine name; mine ID number (MSHA); company name; mine type; and both the Universal Transverse Mercator (UTM) grid zone and the latitude and longitude of the geo-located point on the map. This information is input into the Mine Map Index System. The sorted maps are then scanned into a digital format and stored on the repository's dedicated 500 terabyte mass storage array.[13]
The NMMR utilizes different types of scanning equipment[14] to facilitate archiving mine maps made available in a variety of media.

Coal mining is the process of extracting coal from the ground or from a mine. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a "pit", and above-ground mining structures are referred to as a "pit head". In Australia, "colliery" generally refers to an underground coal mine.
The Coal Region is a region of Northeastern Pennsylvania. It is known for being home to the largest known deposits of anthracite coal in the world with an estimated reserve of seven billion short tons.
For most of the 20th century, the United States Bureau of Mines (USBM) was the primary United States government agency conducting scientific research and disseminating information on the extraction, processing, use, and conservation of mineral resources. The Bureau was abolished in 1996.
The Mine Safety and Health Administration (MSHA) is a large agency of the United States Department of Labor which administers the provisions of the Federal Mine Safety and Health Act of 1977 to enforce compliance with mandatory safety and health standards as a means to eliminate fatal accidents, to reduce the frequency and severity of nonfatal accidents, to minimize health hazards, and to promote improved safety and health conditions in the nation's mines. MSHA carries out the mandates of the Mine Act at all mining and mineral processing operations in the United States, regardless of size, number of employees, commodity mined, or method of extraction. David Zatezalo was sworn in as Assistant Secretary of Labor for Mine Safety and Health, and head of MSHA, on November 30, 2017. He served until January 20, 2021. Jeannette Galanais served as Acting Assistant Secretary by President Joe Biden on February 1, 2021 until Christopher Williamson took office on April 11, 2022.
The Wyoming Valley is a historic industrialized region of Northeastern Pennsylvania. The region is historically notable for its influence in helping fuel the American Industrial Revolution with its many anthracite coal-mines. As a metropolitan area, it is known as the Scranton/Wilkes-Barre metropolitan area, after its principal cities, Scranton and Wilkes-Barre. With a population of 567,559 as of the 2020 United States census, it is the fifth-largest metropolitan area in Pennsylvania, after the Delaware Valley, Greater Pittsburgh, the Lehigh Valley, and the Harrisburg–Carlisle metropolitan statistical areas.
Microforms are scaled-down reproductions of documents, typically either films or paper, made for the purposes of transmission, storage, reading, and printing. Microform images are commonly reduced to about 4% or 1⁄25 of the original document size. For special purposes, greater optical reductions may be used.
The Office of Surface Mining Reclamation and Enforcement (OSMRE) is a branch of the United States Department of the Interior. It is the federal agency entrusted with the implementation and enforcement of the Surface Mining Control and Reclamation Act of 1977 (SMCRA), which attached a per-ton fee to all extracted coal in order to fund an interest-accruing trust to be used for reclamation of abandoned mine lands, as well as established a set environmental standards that mines must follow while operating, and achieve when reclaiming mined land, in order to minimize environmental impact. OSMRE has fewer than 500 employees, who work in either the national office in Washington, DC, or of the many regional and field offices.
The Federal Coal Mine Health and Safety Act of 1969, U.S. Public Law 91-173, generally referred to as the Coal Act, was passed by the 91st United States Congressional session and enacted into law by the 37th President of the United States Richard Nixon on December 30, 1969.
The Sago Mine disaster was a coal mine explosion on January 2, 2006, at the Sago Mine in Sago, West Virginia, United States, near the Upshur County seat of Buckhannon. The blast and collapse trapped 13 miners for nearly two days; only one survived. It was the worst mining disaster in the United States since the Jim Walter Resources Mine disaster in Alabama on September 23, 2001, and the worst disaster in West Virginia since the 1968 Farmington Mine disaster. It was exceeded four years later by the Upper Big Branch Mine disaster, also a coal mine explosion in West Virginia, which killed 29 miners in April 2010.
TheFederal Mine Safety and Health Act of 1977 amended the Coal Mine Safety and Health Act of 1969. It can be found in the United States Code under Title 30, Mineral Lands and Mining, Chapter 22, Mine Safety and Health.
Lackawanna Coal Mine is a museum and retired coal mine that is located in McDade Park in Scranton, Pennsylvania. It opened in 1903.
An abandoned mine refers to a former mining or quarrying operation that is no longer in use and has no responsible entity to finance the cost of remediation and/or restoration of the mine feature or site. Such mines are typically left unattended and may pose safety hazards or cause environmental damage without proper maintenance. The term incorporates all types of old mines, including underground shaft mines and drift mines, and surface mines, including quarries and placer mining. Typically, the cost of addressing the mine's hazards is borne by the public/taxpayers/the government.
The Lehigh Coal and Navigation Company (LCAN) (1988–2010) was a modern-day anthracite coal mining company headquartered in Pottsville, Pennsylvania. It acquired many properties and relaunched the Lehigh Coal Companies brand in 1988. The LCAN ran strip mining operations in the Panther Creek Valley east of Lansford, Pennsylvania along U.S. Route 209 with vast properties dominating the coal areas of Tamaqua, Coaldale, and Lansford.
The history of coal mining in the United States starts with the first commercial use in 1701, within the Manakin-Sabot area of Richmond, Virginia. Coal was the dominant power source in the late 1800s and early 1900s, and although in rapid decline it remains a significant source of energy in 2023.
The CONSOL Energy Mine Map Preservation Project is a project to preserve and digitize maps of underground coal mines in Southwestern Pennsylvania.
Solomon Creek is a tributary of the Susquehanna River in Luzerne County, Pennsylvania, in the United States. It is approximately 8.8 miles (14.2 km) long and flows through Fairview Township, Hanover Township, and Wilkes-Barre. The creek is affected by acid mine drainage and has significant loads of iron, aluminum, and manganese. The creek's named tributaries are Spring Run, Sugar Notch Run, and Pine Creek. The Solomon Creek watershed is located in the Anthracite Valley section of the ridge-and-valley geographical province. Major rock formations in the watershed include the Mauch Chunk Formation, the Spechty Kopf Formation, and the Catskill Formation.
Nanticoke Creek is a tributary of the Susquehanna River in Luzerne County, Pennsylvania, in the United States. It is approximately 4.4 miles (7.1 km) long and flows through Hanover Township and Nanticoke. The watershed of the creek has an area of 7.57 square miles (19.6 km2). The creek has one named tributary, which is known as Espy Run. Nanticoke Creek impaired by pH and metals due to abandoned mine drainage. Abandoned mine drainage discharges in the creek's watershed include the Truesdale Mine Discharge and the Askam Borehole. The creek is located in the Northern Middle Anthracite Field and is in the Anthracite Valley Section of the ridge and valley physiographic province. The main rock formations in the watershed include the Mauch Chunk Formation, the Pottsville Group, and the Llewellyn Formation. The surficial geology consists of coal dumps, surface mining land, alluvium, Wisconsinan Outwash, Wisconsinan Till, urban land, and bedrock.
Mine safety is a broad term referring to the practice of controlling and managing a wide range of hazards associated with the life cycle of mining-related activities. Mine safety practice involves the implementation of recognised hazard controls and/or reduction of risks associated with mining activities to legally, socially and morally acceptable levels. While the fundamental principle of mine safety is to remove health and safety risks to mine workers, mining safety practice may also focus on the reduction of risks to plant (machinery) together with the structure and orebody of the mine.
The Baltimore Mine Tunnel disaster was an explosion that occurred on June 5, 1919 just inside the mouth of Baltimore Tunnel No. 2. The Delaware and Hudson Coal Company's mine employed 450 workers and was located in Wilkes-Barre, Pennsylvania, about a mile from the center of the city near the modern day corner of North Sherman, Spring, and Pine Streets. Ninety-two miners were killed and 44 injured in the explosion, which was caused by the ignition of black blasting powder. Only 7 miners escaped without injury.
