2010 Luotuoshan Coal Mine Flood
The Luotuoshan coal mine flood was an incident that began on Monday, March 1, 2010, when a large amount of water flooded the Luotuoshan coal mine near the city of Wuhai in the Inner Mongolia Autonomous Region of the People's Republic of China. A total of 77 workers were underground when they broke into a large pool of Ordovician limestone water early in the morning. By Monday evening, 45 were rescued and one was confirmed dead. All rescue operations were stopped after 14 days, when medical teams believed that the 31 trapped coal miners had no chance of survival. The rescue work was the largest coal mine mobilization in China's history with 40 professional rescue teams involved, comprising 20,384 people. Infrared surveillance cameras and echo megaphones were used to try to detect life underground, but were unsuccessful. Workers continued pumping water out of the mine and attempting to stop the flooding after the rescue efforts were called off. 3,850 cubic meters of water were being ...

:en:Flooded Mines
A flooded mine is one of the direct results of a mine's closure procedure. When a mine stops operating, its maintenance systems also stop, in which the dewatering systems are included. Without these systems the mine will get flooded by water that naturally occurs in rock formations in the ground. Overview Mining operations can occur over a long period of time, from several years to several decades, and in order to keep the mining operations running, water has to be removed from the mine as it accumulates. After the mine is closed, when its operational life ends, the maintenance systems stop, including the dewatering systems. Without dewatering, the mines tend to flood with surface and groundwaters in the lower levels and mined spaces, if there is not a drainage adit present. The flooding process of an open-pit or underground mine can take from a several months period to more than a decade, depending on factors such as volume of open space in the mine, availability of infiltrat ...

Wuhai
Wuhai (; mn, ''Üqai qota'', Mongolian cyrillic.Үхай хот) is a prefecture-level city and regional center in the Inner Mongolia Autonomous Region, China, and is by area the smallest prefecture-level division of the region. It is located on the Yellow River between the Gobi and Ordos deserts. Wuhai became a single city occupying both banks of the Yellow River with the amalgamation on 1976 of left-bank (west) Wuda (then administrated by Bayan Nuur League) together with Haibowan on the right (east) bank (then administrated by Ikh Juu league). Wuhai is one of very few cities with an antipode which is not only on land (as opposed to open ocean), but which is another inhabited city; the antipode of Wuhai is almost exactly on the city of Valdivia, Chile. Football commentator and Television host Huang Jianxiang is born here. History The modern location of Wuhai was originally composed of two towns: Wuda which lied on the western side of the Yellow River and Haibowan which ...

Ordovician
The Ordovician ( ) is a geologic period and System (geology), system, the second of six periods of the Paleozoic Era (geology), Era. The Ordovician spans 41.6 million years from the end of the Cambrian Period million years ago (Mya) to the start of the Silurian Period Mya. The Ordovician, named after the Celtic Britons, Welsh tribe of the Ordovices, was defined by Charles Lapworth in 1879 to resolve a dispute between followers of Adam Sedgwick and Roderick Murchison, who were placing the same Rock (geology), rock beds in North Wales in the Cambrian and Silurian systems, respectively. Lapworth recognized that the fossil fauna in the disputed Stratum, strata were different from those of either the Cambrian or the Silurian systems, and placed them in a system of their own. The Ordovician received international approval in 1960 (forty years after Lapworth's death), when it was adopted as an official period of the Paleozoic Era by the International Union of Geological Sciences, Intern ...

Water Glass
Sodium silicate is a generic name for chemical compounds with the formula or ·, such as sodium metasilicate , sodium orthosilicate , and sodium pyrosilicate . The anions are often polymeric. These compounds are generally colorless transparent solids or white powders, and soluble in water in various amounts. Sodium silicate is also the technical and common name for a mixture of such compounds, chiefly the metasilicate, also called waterglass, water glass, or liquid glass. The product has a wide variety of uses, including the formulation of cements, passive fire protection, textile and lumber processing, manufacture of refractory ceramics, as adhesives, and in the production of silica gel. The commercial product, available in water solution or in solid form, is often greenish or blue owing to the presence of iron-containing impurities. In industry, the various grades of sodium silicate are characterized by their SiO2:Na2O weight ratio (which can be converted to molar ratio ...

2010 Wangjialing Coal Mine Flood
The Wangjialing coal mine flood was an incident that began on Sunday, March 28, 2010, when underground water flooded parts of the Wangjialing coal mine in the Shanxi province of People's Republic of China. A total of 261 people were in the mine when workers first broke through an abandoned shaft that was filled with water. Over 100 managed to escape, but 153 workers were trapped in nine different platforms of the mine. Television reports spoke of the survivors attaching themselves by belts to the wall of the mine as waters rushed in. They hung there for three days until a mine cart drifted by and they got in. Most workers are safe with a few dozen still trapped as of 5 April, if the official numbers are correct; families claim the actual number is higher. The mine belongs to state-owned Huajin Coking Coal Co. Ltd. At the time, workers were building the mine's infrastructure to allow it to produce 6 million tons of coal per year at full production.

Coal Mining Disasters In China
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2010 Disasters In China
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
