Dome Mine is situated in the City of Timmins, Ontario, Canada; and was developed during the Porcupine Gold Rush.
The Ida Dome mine is a large mine located in the western part of Namibia in Erongo Region.
 Ida Dome represents one of the largest uranium reserves in Namibia, with estimated reserves of 53 million tonnes of ore grading 0.018% uranium.
Mine planter and the earlier "torpedo planter" was a term used for mine warfare ships into the early days of World War I.
 In later terminology, particularly in the United States, a mine planter was a ship specifically designed to install controlled mines or contact mines in coastal fortifications.
 This type of ship diverged in both function and design from a ship operating as a naval minelayer.
 Though the vessel may be seagoing it is not designed to lay large numbers of mines in open sea.
 A mine planter was designed to place controlled minefields in exact locations so that they might be fired individually or as a group from shore when observers noted a target to be at or near a designated mine's position.
 The terms and types of specialized ship existed from the 1860s where "torpedoes" were made famous in the American Civil War until the demise of large, fixed coastal fortifications brought on by the changes of World War II.
In World War II, the United States Navy needed a vessel that could consistently locate mines in [foreign or domestic?]
 or littoral waters.
 Littoral waters are found between the shore line and waters 60 meters deep.
 The Accentor-class minesweeper (sometimes called the Accentor/Acme-class minesweeper) was developed for this task.
 This class of minesweeper was named after the Accentor bird, Prunella modularis.
 This bird is endemic to Europe, Asia, and North Africa which is the area that World War II occurred.
 The bird is a drab brown and gray color and is in the same family as warblers and thrushes.
 The Accentor-class mine sweeper was designed for the sweeping of mines in harbors, bays, and other littoral waters.
 The Accentor-class minesweeper had a wooden hull for three reasons.
 The first was that some of the mines that the Accentor-class minesweeper was trying to detect were detonated by a copper wire coming out of the top of the mine that is used to detect the magnetic field that is produced by the metal hulls of most ships; when the wire senses a magnetic field, it detonates the mine.
 Minesweepers use wooden hulls because wood is a non-magnetic material, unlike steel, and would not set off this type of mine.
 The second is that wooden hulls were lighter than metal hulls.
 This caused them to float higher in the water, which made them displace less water and have a smaller pressure wave, so pressure mines would not be set off by the movement of the ship.
 Lastly, due to the ship floating higher in the water, contact mines were not effective because they were often around 20 feet below the surface of the water, and the draft of this class of ship was between 8 feet 11 inches and 10 feet 8 inches.
 Typically, the Accentor-class minesweepers were armed with a pair of .50 caliber machine guns for protection.
 Rather than creating new minesweeping vessels, forty-five wooden-hulled fishing boats were converted into Accentor-class minesweepers.
 This saved the Navy both time and money.
 Since these converted fishing boats were not all the same, their specifications do vary a bit.
 The converted fishing boats had a displacement from 165 to 270 tons of water.
 They had speeds from 8.5 up to 14 knots and crews from as small as 15 up to 50.
Crisson Mine was a gold mine in Lumpkin County, Georgia, USA, located just east of Dahlonega.
 Like many mines in the area, the property probably started as a placer mine during the Georgia Gold Rush.
 Once the placer deposits had been exhausted, an open pit gold mine was established in 1847 and commercial operations continued until the early 1980s.
 A small stamp mill was also established here.
 Much of the gold used for the gold leaf dome of the Georgia State Capitol was mined at this mine, which was among the most productive mine in the Georgia Gold Belt.
 The mine is located just north of the site of the Consolidated Mine, which is itself north of and the Calhoun Mine.
Type 500 training mine was jointly developed by Fengxi Machinery Factory (汾西机器厂) and the First Division of the People’s Liberation Army Naval Air Force.
 This training mine is very similar to the Training-1 training bottom mine except that Type 500 training mine can be planted by aircraft.
 It is used to train pilots to drop mines into the ocean.
 Like the Training-1 training bottom mine, this mine can also be rapidly converted into live round by adopting warheads on regular mines.
The P2 Mk2 and P3 Mk2 are Pakistani plastic cased minimum metal anti-tank blast mines.
 The P2 Mk2 has a square case with a central circular ribbed pressure plate, the P3 is circular with a central circular pressure plate.
 Both mines use anti-personnel mines as the fuse, typically the either the P4 Mk1 or P2 Mk2 anti-personnel mines.
 The anti-personnel mine sits in a cavity below the pressure plate, when enough pressure is place on the pressure plate of the mine, it collapses onto the anti-personnel mine triggering it and the main charge which sits below it.
 A yellow canvas carrying strap is normally fitted to the side of the mine.
 The mines have a secondary fuse well on the bottom which can be used with anti-handling devices.
 A GLM-2 electronic booby trap can be fitted to the cavity under the pressure plate.
 The mine is supplied with a steel disc which makes the mine more easily detectable, although this is seldom used.
 Since 1997 only a detectable version of the mine has been produced, and to comply with the Convention on Conventional Weapons amended protocol II, Pakistani stocks of the mine are being retrofitted with steel detection discs.
 The mines are found in Afghanistan, Angola, Eritrea, Ethiopia, Pakistan, Somalia, and Tajikistan.
The Camlaren Mine was a small gold mine 80 km north-east of Yellowknife, Northwest Territories, Canada at Gordon Lake.
 It consists of a property totaling about 981 hectares.
 The two claims that make up the property were staked in 1936 by prospectors Don Cameron and the Mclaren brothers and developed with two shafts during 1937-1938.
 The name "Camlaren" is a portmanteau of Cameron and McLaren.
 Conditions attributed to World War II halted development at Camlaren in 1939.
The National Mine Map Repository (NMMR) is part of the United States Department of the Interior (DOI), Office of Surface Mining Reclamation and Enforcement (OSMRE or OSM).
 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.
 The Green Tree facility provides and stores, digitally and in microfilm (aperture cards), over 182,000 maps of abandoned mines.
 This repository contains maps of mine workings from the 1790s to the present day.
 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, 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.
The Colomac Mine was a privately owned and operated open pit gold mine located 220 km northwest of Yellowknife in the Northwest Territories in Canada .
 The Colomac mine operated between 1990–1992, and 1994–1997.
 It was operated by Neptune Resources Limited that had little success in making a profit during its operation.
 In 1994, the mine had reopened under Royal Oak Mines Inc.
 Both Neptune Resources and Royal Oak Mines where both owned and operated by Peggy Witte.
 Due to low gold prices and high cost of mining, Royal Oak Mines was forced into bankruptcy.
 The Federal Government of Canada became owners of the mine, along with the related environmental issues.
 A major cleanup effort is under way to prevent the mine from polluting the environment, but this might be too late at this stage.
 This mine is now owned and controlled by the Indigenous and Northern Affairs department of the Federal government, while Public Works and Government services is the current contracting authority.
