Yunkom Coal Mine
Yunkom coal mine (), officially named the Yuny Kommunar Mine, was a coal mine in the town of Bunhe in eastern Ukraine. The mine first opened in 1912, and was closed in 2018. History This mine was first put into operation in 1912. In 1914, a jackhammer was used here for the first time. Nuclear explosion In 1979, Soviet authorities conducted a peaceful nuclear explosion underground at the "Klivazh" site within the Yunkom mine. This was done to prevent frequent coal and rock releases, and was conducted below the surface. Decline Production significantly plummeted during the 1990s, shortly after the collapse of the Soviet Union. In 1990, the mine's production was at around 1446 t/day, which was at about 330 by 1999. The length of underground workings also fell from in 1990 to by 1999. The number of workers declined from 1755 people in 1990 to just 662 by 1999. Flooding of the mine In 2018, the administration of the self-proclaimed Donetsk People's Republic, which have con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The elevation is up to 200 meters. History It was founded in 1908 when the Russian-Belgium Metallurgical Association founded Bunge mine to supply coal to Petrovskiy steelworks (now Yenakiieve Iron and Steel Works). The name Bunhe or Bunge comes from the German surname Bunge (surname), Bunge. In 1924, the Yunkom coal mine was named "Yunkom" ("Yuny communar"; ) and the settlement was named "Yunokomunarivsk". In 1965 it received urban-type settlement status. On 16 September 1979, in the mine "Yuny Communar" there was one of the Nuclear Explosions for the National Economy—an object "Klivazh". In 2002 the mine was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coal Mines In Ukraine
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radionuclide
A radionuclide (radioactive nuclide, radioisotope or radioactive isotope) is a nuclide that has excess nuclear energy, making it unstable. This excess energy can be used in one of three ways: emitted from the nucleus as gamma radiation; transferred to one of its electrons to release it as a conversion electron; or used to create and emit a new particle ( alpha particle or beta particle) from the nucleus. During those processes, the radionuclide is said to undergo radioactive decay. These emissions are considered ionizing radiation because they are energetic enough to liberate an electron from another atom. The radioactive decay can produce a stable nuclide or will sometimes produce a new unstable radionuclide which may undergo further decay. Radioactive decay is a random process at the level of single atoms: it is impossible to predict when one particular atom will decay. However, for a collection of atoms of a single nuclide the decay rate, and thus the half-life (''t''1/2) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Half-life
Half-life (symbol ) is the time required for a quantity (of substance) to reduce to half of its initial value. The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive. The term is also used more generally to characterize any type of exponential (or, rarely, non-exponential) decay. For example, the medical sciences refer to the biological half-life of drugs and other chemicals in the human body. The converse of half-life (in exponential growth) is doubling time. The original term, ''half-life period'', dating to Ernest Rutherford's discovery of the principle in 1907, was shortened to ''half-life'' in the early 1950s. Rutherford applied the principle of a radioactive element's half-life in studies of age determination of rocks by measuring the decay period of radium to lead-206. Half-life is constant over the lifetime of an exponentially decaying quantity, and it is a characteristic u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strontium
Strontium is the chemical element with the symbol Sr and atomic number 38. An alkaline earth metal, strontium is a soft silver-white yellowish metallic element that is highly chemically reactive. The metal forms a dark oxide layer when it is exposed to air. Strontium has physical and chemical properties similar to those of its two vertical neighbors in the periodic table, calcium and barium. It occurs naturally mainly in the minerals celestine and strontianite, and is mostly mined from these. Both strontium and strontianite are named after Strontian, a village in Scotland near which the mineral was discovered in 1790 by Adair Crawford and William Cruickshank; it was identified as a new element the next year from its crimson-red flame test color. Strontium was first isolated as a metal in 1808 by Humphry Davy using the then newly discovered process of electrolysis. During the 19th century, strontium was mostly used in the production of sugar from sugar beets (see str ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cesium
Caesium ( IUPAC spelling) (or cesium in American English) is a chemical element with the symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal with a melting point of , which makes it one of only five elemental metals that are liquid at or near room temperature. Caesium has physical and chemical properties similar to those of rubidium and potassium. It is pyrophoric and reacts with water even at . It is the least electronegative element, with a value of 0.79 on the Pauling scale. It has only one stable isotope, caesium-133. Caesium is mined mostly from pollucite. The element has 40 known isotopes, making it, along with barium and mercury, one of the elements with the most isotopes. Caesium-137, a fission product, is extracted from waste produced by nuclear reactors. The German chemist Robert Bunsen and physicist Gustav Kirchhoff discovered caesium in 1860 by the newly developed method of flame spectroscopy. The first small-scale applications for ...
