Coalbrook Mining Disaster
The Coalbrook mining disaster is the worst mining accident in the history of South Africa. The disaster occurred in the Coalbrook coal mine of Clydesdale Colliery on 21 January 1960 at around 19:00 when approximately 900 pillars caved in, almost underground. The mine is situated in the Northern Free State, south west of Vereeniging. About 1,000 miners were in the mine at the time and 437 died after being trapped, while the rest escaped through an incline shaft. The miners were suffocated by methane gas and crushed to death by rockfall. Miners felt a strong blast wind, many of whom rushed up to the surface but were instructed to return underground or face imprisonment. Only two miners refused to go back underground. The majority of the miners at Clydesdale Colliery were Lesotho and Mozambique nationals. Immediately after the incident, rescue teams arrived from other mines in the region and boreholes were drilled into areas where survivors were expected to be. When microphon ...

Carbon Monoxide
Carbon monoxide (chemical formula CO) is a colorless, poisonous, odorless, tasteless, flammable gas that is slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest molecule of the oxocarbon family. In coordination complexes the carbon monoxide ligand is called carbonyl. It is a key ingredient in many processes in industrial chemistry. The most common source of carbon monoxide is the partial combustion of carbon-containing compounds, when insufficient oxygen or heat is present to produce carbon dioxide. There are also numerous environmental and biological sources that generate and emit a significant amount of carbon monoxide. It is important in the production of many compounds, including drugs, fragrances, and fuels. Upon emission into the atmosphere, carbon monoxide affects several processes that contribute to climate change. Carbon monoxide has important biological roles across phylogenetic ...

Mining In South Africa
Mining in South Africa was once the main driving force behind the history and development of Africa's most advanced and richest economy. Large-scale and profitable mining started with the discovery of a diamond on the banks of the Orange River in 1867 by Erasmus Jacobs and the subsequent discovery and exploitation of the Kimberley pipes a few years later. Gold rushes to Pilgrim's Rest and Barberton were precursors to the biggest discovery of all, the Main Reef/Main Reef Leader on Gerhardus Oosthuizen's farm Langlaagte, Portion C, in 1886, the Witwatersrand Gold Rush and the subsequent rapid development of the gold field there, the biggest of them all. Diamond and gold production are now well down from their peaks, though South Africa is still number 5 in gold but remains a cornucopia of mineral riches. It is the world's largest producer of chrome, manganese, platinum, vanadium and vermiculite. It is the second largest producer of ilmenite, palladium, rutile and zirconium. ...

Coal In South Africa
South Africa produces in excess of 255 million tonnes of coal (2011 estimate) and consumes almost three-quarters of that domestically. As of 2018, South Africa was the seventh largest producer and consumer of coal in the world. This large industry, means that as of 2015 about 80,000 workers, or .5% of total employment, was from the coal industry, down from a peak in 1981 of 135,000 workers. The coal industry is South Africa's largest contribution to the greenhouse gases that cause climate change. Around 77% of South Africa's energy needs are directly derived from coal. South Africa is the 5th largest exporter of coal in the world, with 30% consumed overseas. 92% of coal consumed on the African continent is produced in South Africa. 80% of South Africa's emissions come from the energy supply which is dependent on coal, which produced the vast majority of the country's energy, or 42GWs.

Mining Disasters In South Africa
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials ...

2010 Copiapó Mining Accident
The 2010 Copiapó mining accident, also known then as the "Chilean mining accident", began on 5 August 2010, with a cave-in at the San José copper–gold mine, located in the Atacama Desert north of the regional capital of Copiapó, in northern Chile. Thirty-three men, trapped underground and from the mine's entrance via spiraling underground ramps, were rescued after 69 days. After the state-owned mining company, Codelco, took over rescue efforts from the mine's owners, exploratory boreholes were drilled. Seventeen days after the accident, a note was found taped to a drill bit pulled back to the surface: "Estamos bien en el refugio los 33" ("We are well in the shelter, the 33 of us"). Three separate drilling rig teams; nearly every Chilean government ministry; the United States' space agency, NASA; and a dozen corporations from around the world cooperated in completing the rescue. On 13 October 2010 the men were winched to the surface one at a time, in a specially buil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South African Chamber Of Mines
The Minerals Council South Africa is a South African mining-industry employer organisation. Its members include famous South African mining houses such as Anglo American, De Beers, Gold Fields and Harmony. In its current form, it was founded in 1968 as the Chamber of Mines, a South African wide organization. Prior to that year, it has its early origins as the Transvaal Chamber of Mines in 1887, then evolved over many years reforming as the Witwatersrand Chamber of Mines in 1889, the Chamber of Mines of the South African Republic from 1897, Transvaal Chamber of Mines from 1902 and lastly from 1953 until 1967 as the Transvaal and Orange Free State Chamber of Mines. On 23 May 2018, the South African Chamber of Mines rebranded themselves as the Minerals Council South Africa. Early history On 21 October 1887, the Transvaal Chamber of Mines met for the first time at Central Hotel in Johannesburg.

Methane
Methane ( , ) is a chemical compound with the chemical formula (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas. The relative abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it poses technical challenges due to its gaseous state under normal conditions for temperature and pressure. Naturally occurring methane is found both below ground and under the seafloor and is formed by both geological and biological processes. The largest reservoir of methane is under the seafloor in the form of methane clathrates. When methane reaches the surface and the atmosphere, it is known as atmospheric methane. The Earth's atmospheric methane concentration has increased by about 150% since 1750, and it accounts for 20% of the total radiative forcing from all of the long-lived and globally mixed greenhouse gases. It has also been detected on other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
