Mining is the extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water.
Underground hard-rock mining refers to various underground mining techniques used to excavate "hard" minerals, usually those containing metals, such as ore containing gold, silver, iron, copper, zinc, nickel, tin, and lead. It also involves the same techniques used to excavate ores of gems, such as diamonds and rubies. Soft-rock mining refers to the excavation of softer minerals, such as salt, coal, and oil sands.
Beaconsfield is a former gold mining town near the Tamar River, in the north-east of Tasmania, Australia. It lies 40 kilometres north of Launceston on the West Tamar Highway. It is a rural and residential locality in the local government areas (LGA) of West Tamar and Latrobe in the Launceston and North-west and west LGA regions of Tasmania. The 2016 census has a population of 1298 for the state suburb of Beaconsfield.
A mining accident is an accident that occurs during the process of mining minerals or metals. Thousands of miners die from mining accidents each year, especially from underground coal mining, although accidents also occur in hard rock mining. Coal mining is considered much more hazardous than hard rock mining due to flat-lying rock strata, generally incompetent rock, the presence of methane gas, and coal dust. Most of the deaths these days occur in developing countries, and rural parts of developed countries where safety measures are not practiced as fully. A mining disaster is an incident where there are five or more fatalities.
The TauTona Mine or Western Deep No.3 Shaft, was a gold mine in South Africa. At approximately 3.9 kilometers (2.4 mi) deep, it was home to the world's second deepest mining operation, rivalled only by the Mponeng Gold Mine, but was closed in 2018.
Drift mining is either the mining of an ore deposit by underground methods, or the working of coal seams accessed by adits driven into the surface outcrop of the coal bed. A drift mine is an underground mine in which the entry or access is above water level and generally on the slope of a hill, driven horizontally into the ore seam.
Galamsey, derived from the phrase "gather them and sell", is local Ghanaian parlance that means illegal small-scale, gold mining in Ghana. Such workers are known as galamseyers or orpailleurs in neighboring Francophone nations. Galamseyers are people who perform illegal gold mining independent of mining companies, digging small working pits, tunnels, and sluices by hand. Galamsey is also referred to as Illegal Artisanal Small Scale mining (ASM).
Harmony Gold is the largest gold mining company in South Africa. Harmony operates in South Africa and in Papua New Guinea. The company has nine underground mines, one open-pit mine and several surface operations in South Africa. In Papua New Guinea, it has Hidden Valley, an open-pit gold and silver mine and a 50% interest in the Morobe Mining Joint Venture, which includes the Wafi-Golpu project and extensive exploration tenements. Outside the joint venture, Harmony's own exploration portfolio focuses principally on highly prospective areas in Papua New Guinea.
The Treadwell gold mine was on the south side of Douglas Island, .5-mile (0.80 km) east of downtown Douglas and southeast of downtown Juneau, owned and operated by John Treadwell. Composed of four sub-sites, Treadwell was in its time the largest hard rock gold mine in the world, employing over 2,000 people. Between 1881 and 1922, over 3 million troy ounces of gold were extracted. Not much remains today except for a few crumbling buildings and a "glory hole". Although John Treadwell had twelve years of experience in both placer and lode mines, he was a carpenter and builder by trade who had come to Alaska prior to the Klondike Gold Rush.
The Crandall Canyon Mine, formerly Genwal Mine, was an underground bituminous coal mine in northwestern Emery County, Utah.
The 2008 Ukrainian coal mine collapse occurred at the Karl Marx Coal Mine in the city of Yenakiieve, Donetsk Oblast (province) of eastern Ukraine on June 8, 2008. The mine collapse was said to have been caused by a gas pipe explosion. The explosion occurred at a depth of about 1,750 feet (533 m). 37 miners were trapped underground at the time of the collapse, located 3,301 feet (1,006 m) below the surface of the earth. Additionally, five surface workers suffered from burns and other injuries in a blast that they described as one of the most powerful in the industry.
Waiuta is the location of a historic mining town on the West Coast of the South Island of New Zealand. It is now abandoned and considered a ghost town. Located 58 km north of Greymouth and 21 km south of Reefton in Ikamatua, New Zealand, it was the site of a gold mine until 1951 when the collapse of the mine made it uneconomic. A number of buildings remain and there are still residents in what remains of the town. Nowadays Waiuta has become a tourist attraction, with few of the original buildings still intact that include the former police station, three cottages and the old barber shop.
The 2009 Harmony Gold mine deaths occurred in late May and early June 2009 in Free State province, South Africa. At least 82 miners, many from Lesotho, Mozambique and Zimbabwe, died from inhalation of poisonous gasses created by a May 18 fire in the mineshaft.

Fatality statistics in the Western Australian mining industry captures the number of people killed in the industry in the Australian state of Western Australia. During the period 2000-2012 (inclusive), a total of 52 fatalities occurred. In 2006, the Chamber of Minerals and Energy of Western Australia commissioned a taxonomic study to analyse the 306 mining fatalities which occurred between 1970 and 2006. The Department of Mines and Petroleum, later renamed the Department of Mines, Industry Regulation and Safety, the governing authority for the industry in the state, has published statistics for fatalities in mining dating back to 1943 and intends to publish statistics dating back to 1886, though early records are not expected to be exhaustive.
The Giroux Consolidated Company experienced two mining accidents at a copper mine in Ely, Nevada, one on December, 4 1907 and another on August 24, 1911.
The Niger gold mine collapse occurred on 7 November 2021 when a manually dug well collapsed at the Garin-Liman mining area of Maradi region, Niger. The day of the mine disaster left 18 people dead on the spot, 7 injured and hospitalised, and dozens of miners buried underground waiting to be rescued. However, equipment limitations have slowed the rescue process. On 9 November 2021, two days after the mine disaster, rescuers found more bodies in the collapsed mine. Eventually, the number of people killed in the accident rose to 32. Since the incident took place on the border between Niger and Nigeria, a large number of Nigerians work in the area. According to reports, among the victims, 13 were Nigerians.
