	~~==Overview==~~		The '''National Mine Map Repository''' (NMMR) is a facility established by the United States Department of the Interior to maintain and preserve mine maps and other related documents. Located in Pittsburgh, Pennsylvania, the repository serves as a central archive for maps of abandoned mines throughout the United States. The NMMR is an essential resource for mining engineers, geologists, historians, and environmental scientists.
	The National Mine Map Repository is a ~~significant archive that houses mine maps, data, and related documents from across~~ the United States~~. Its primary mission is~~ to ~~collect,~~ preserve~~, and make accessible~~ mine maps and related ~~data to federal~~, ~~state, and local governments~~, the ~~mining industry, and~~ the ~~general public~~. The NMMR ~~serves as a critical tool~~ for ~~addressing issues related to mine safety~~, ~~mine reclamation~~, and environmental ~~protection~~.

	==History==		==History==
	The ~~establishment of the~~ NMMR was ~~motivated by~~ the ~~need to improve mine safety~~ and ~~to facilitate~~ the ~~reclamation~~ of ~~abandoned~~ mine ~~lands. Over~~ the ~~years,~~ the repository ~~has grown~~ to ~~include a vast collection~~ of ~~mine maps and related documents~~, which are ~~invaluable~~ for understanding the ~~development~~ and ~~impact~~ of ~~mining in the United States~~.		The NMMR was established in 1970 in response to the Federal Coal Mine Health and Safety Act of 1969, which mandated the preservation of mine maps to ensure the safety of miners and the public. The repository was created to collect, preserve, and provide access to maps of abandoned mines, which are crucial for understanding the layout and conditions of these mines.

	==Collection==		==Collection==
	The ~~NMMR's~~ collection ~~includes a wide range~~ of ~~materials~~, ~~such as underground~~ and ~~surface mine~~ maps, ~~geological and geophysical~~ maps, and ~~engineering and construction drawings~~. ~~These documents provide detailed information about~~ mine ~~layouts~~, ~~geological formations~~, and ~~the location of natural and man-made features relevant to mining operations~~.		The repository houses an extensive collection of mine maps, including those from coal, metal, and non-metal mines. The maps vary in age, with some dating back to the 19th century. The collection includes hand-drawn maps, blueprints, and modern digital maps. The maps are used for various purposes, including mine safety, land reclamation, and historical research.

	==~~Services~~==		[[File:Hazleton Coal Company.jpg\|thumb\|A map from the Hazleton Coal Company]]
	The NMMR ~~offers several services~~ to its users, ~~including map searches~~, ~~digital scanning~~ and ~~reproduction of~~ maps, and ~~technical assistance~~ in ~~interpreting map data~~. ~~These services are essential for supporting mine safety initiatives~~, ~~environmental studies~~, ~~and land~~ use ~~planning~~.
			==Access and Use==
			The NMMR provides access to its collection through an online database, where users can search for maps by location, mine name, or other criteria. The repository also offers assistance to individuals and organizations seeking specific maps or information. Researchers and professionals can visit the repository in person to view maps and documents.

			==Technological Advancements==
			The NMMR has embraced technological advancements to improve access to its collection. The repository has digitized many of its maps, making them available online. Additionally, the use of touch table technology allows users to interact with digital maps in innovative ways.

	==Importance==		==Importance==
	The ~~repository's collection is an invaluable resource~~ for ~~various stakeholders, including:~~		The maps preserved by the NMMR are vital for ensuring the safety of current mining operations and for planning land use in areas with abandoned mines. They help prevent accidents by providing detailed information about the location and condition of old mine workings. The maps are also valuable for historical research, offering insights into the history of mining in the United States.
	* '''Mine Safety:''' Helps in ~~assessing and managing risks associated~~ with ~~old and active~~ mines.
	* '''Environmental Protection:''' Supports efforts to mitigate the ~~environmental impact~~ of ~~mining activities~~.
	* '''Historical Research:''' Provides insights into the history of mining ~~regions and the development of mining technology.~~

	~~==Challenges==~~
	~~Maintaining and expanding the NMMR's collection is a significant challenge, given the vast number of mines~~ in the United States ~~and the historical nature of many documents. Digitization and preservation of aging maps are ongoing efforts to ensure that this valuable information remains accessible to future generations~~.
