Raspadskaya Coal Mine
The Raspadskaya Coal Mine is a coal mine located in Mezhdurechensk, Kemerovo Oblast, Russia. It is the largest coal and the largest underground mine in Russia. The mine was opened in 1973 and its construction was completed in 1977. In addition to the main underground mine, the mining complex also includes MUK-96 underground mine, Raspadskaya Koksovaya underground mine, and Razrez Raspadsky open-pit mine, as also the Raspadskaya preparation plant. The mine is the largest coal mine in Russia. Raspadskaya's total resources were estimated at 1,461 million tons and total coal reserves at 782 million ton (JORC standards, according to IMC Consulting report as of June 2006, of which 22 million tons produced by 31 March 2008). Based on the volume produced in 2007, reserves-to-production ratio amounts to about 55 years of production. The complex produces 10% of Russia's coking coal. The mine is owned and operated by Raspadskaya OAO, a Russian publicly listed coal company. In M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reserves-to-production Ratio
The reserves-to-production ratio (RPR or R/P) is the remaining amount of a non-renewable resource, expressed in time. While applicable to all natural resources, the RPR is most commonly applied to fossil fuels, particularly petroleum and natural gas. The ''reserve'' portion (numerator) of the ratio is the amount of a resource known to exist in an area and to be economically recoverable (proven reserves). The ''production'' portion (denominator) of the ratio is the amount of resource produced in one year at the current rate. ''RPR = (amount of known resource) / (amount used per year)'' This ratio is used by companies and government agencies in forecasting the future availability of a resource to determine project life, future income, employment, etc., and to determine whether more exploration must be undertaken to ensure continued supply of the resource. Annual production of a resource can usually be calculated to quite an accurate number. However, reserve quantities can only be est ...

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 plane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short Ton
The short ton (symbol tn) is a measurement unit equal to . It is commonly used in the United States, where it is known simply as a ton, although the term is ambiguous, the single word being variously used for short, long, and metric ton. The various tons are defined as units of mass.Butcher, Crown and Gentry, NIST Special Publication 1038, The International System of Units (SI) – Conversion Factors for General Use, 2006 They are sometimes used as units of weight, the force exerted by a mass at standard gravity (e.g., short ton-force). One short ton exerts a weight at one standard gravity of 2,000 pound-force (lbf). United States In the United States, a short ton is usually known simply as a "ton", without distinguishing it from the tonne (), known there as the "metric ton", or the long ton also known as the "imperial ton" (). There are, however, some U.S. applications where unspecified ''tons'' normally mean long tons (for example, naval ships) or metric tons (world grain ...

Metric Tons
The tonne ( or ; symbol: t) is a unit of mass equal to 1000 kilograms. It is a non-SI unit accepted for use with SI. It is also referred to as a metric ton to distinguish it from the non-metric units of the short ton ( United States customary units), and the long ton ( British imperial units). It is equivalent to approximately 2204.6 pounds, 1.102 short tons, and 0.984 long tons. The official SI unit is the megagram (symbol: Mg), a less common way to express the same mass. Symbol and abbreviations The BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879.Table 6 . BIPM. Retrieved on 2011-07-10. Its use is also official for the metric ton in the United States, having been adopted by the United States |
Earth Observation Satellite
An Earth observation satellite or Earth remote sensing satellite is a satellite used or designed for Earth observation (EO) from orbit, including spy satellites and similar ones intended for non-military uses such as environmental monitoring, meteorology, cartography and others. The most common type are Earth imaging satellites, that take satellite images, analogous to aerial photographs; some EO satellites may perform remote sensing without forming pictures, such as in GNSS radio occultation. The first occurrence of satellite remote sensing can be dated to the launch of the first artificial satellite, Sputnik 1, by the Soviet Union on October 4, 1957. Sputnik 1 sent back radio signals, which scientists used to study the ionosphere. The United States Army Ballistic Missile Agency launched the first American satellite, Explorer 1, for NASA’s Jet Propulsion Laboratory on January 31, 1958. The information sent back from its radiation detector led to the discovery of the Earth's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raspadskaya Mine Explosion
The Raspadskaya mine explosion was a mine explosion in the Raspadskaya mine, located near Mezhdurechensk in Kemerovo Oblast, Russia, which occurred on 8 May 2010. It was believed to have been caused by a buildup of methane. The initial explosion was followed by a second approximately four hours later which collapsed the mine's ventilation shaft and trapped several rescue workers. By 18 May 2010, 66 people were confirmed to have died with at least 99 others injured and as many as a further 24 unaccounted for. History The mine, owned by Russian company Raspadskaya, is the largest underground coal mine in Russia, producing 10% of the country's coking coal. It has a history of accidents and safety problems. In March 2001, another methane explosion killed four miners and injured six. The mine was shut down for two weeks in 2008 due to safety violations and a worker was killed after part of the mine collapsed in January 2010.

Coking Coal
Metallurgical coal or coking coal is a grade of coal that can be used to produce good-quality coke. Coke is an essential fuel and reactant in the blast furnace process for primary steelmaking. The demand for metallurgical coal is highly coupled to the demand for steel. Primary steelmaking companies often have a division that produces coal for coking, to ensure a stable and low-cost supply. Metallurgical coal comes mainly from Canada, the United States, and Australia, with Australia exporting 58% of seaborne trade, mostly going to China. In the United States, the electric power sector used "93% of total U.S. coal consumption between 2007 and 2018"; only 7% of the total was metallurgical coal and coal for other uses such as heating. Characteristics Metallurgical coal is low in ash, moisture, sulfur and phosphorus content, and its rank is usually bituminous. Some grades of anthracite coal are used for sintering, pulverized coal injection, direct blast furnace charge, pelleti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open-pit Mining
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburden is relatively thin or the material of interest is structurally unsuitable for tunnelling (as would be the case for cinder, sand, and gravel). In contrast, minerals that have been found underground but are difficult to retrieve due to hard rock, can be reached using a form of underground mining. To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting ea ...
