The National Mine Map
History
The
.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.
Available information
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:
- Mine and company names
- Underground mine plans
- Mains, rooms, and pillars
- Man-ways, shafts, mine surface openings, barrier pillars and ventilation facilities
- Mains, rooms, and
- Closure (final) maps
- Adjacent mines
- Geologicalinformation
- Geographicaldata
- Abandoned railroad lines and stations, coal towns, surface facilities, roads, ponds, streams, and property survey points
- Districts, townships, sections, ranges, counties and municipalities, latitudes and longitudes, elevation bench marks, and surface elevations
- Gas well, oil well, and drill hole locations[11]
Map acquisition and archiving
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 (
The NMMR utilizes different types of scanning equipment[14] to facilitate archiving mine maps made available in a variety of media.
