Asbestos
Asbestos () is a naturally occurring fibrous silicate mineral. There are six types, all of which are composed of long and thin fibrous crystals, each fibre being composed of many microscopic "fibrils" that can be released into the atmosphere by abrasion and other processes. Inhalation of asbestos fibres can lead to various dangerous lung conditions, including mesothelioma, asbestosis, and lung cancer, so it is now notorious as a serious health and safety hazard. Archaeological studies have found evidence of asbestos being used as far back as the Stone Age to strengthen ceramic pots, but large-scale mining began at the end of the 19th century when manufacturers and builders began using asbestos for its desirable physical properties. Asbestos is an excellent electrical insulator and is highly fire-resistant, so for much of the 20th century it was very commonly used across the world as a building material, until its adverse effects on human health were more widely acknowledged ...

Chrysotile
Chrysotile or white asbestos is the most commonly encountered form of asbestos, accounting for approximately 95% of the asbestos in the United StatesOccupational Safety and Health Administration, U.S. Department of Labor (2007)29 C.F.R. 1910.1001 Appendix J. and a similar proportion in other countries.Institut national de recherche sur la sécurité (1997).Amiante." ''Fiches toxicologiques.'' n° 167. (in French) It is a soft, fibrous silicate mineral in the serpentine subgroup of phyllosilicates; as such, it is distinct from other asbestiform minerals in the amphibole group. Its idealized chemical formula is Mg( Si O)( OH). The material has physical properties which make it desirable for inclusion in building materials, but poses serious health risks when dispersed into air and inhaled. Polytypes Three polytypes of chrysotile are known. These are very difficult to distinguish in hand specimens, and polarized light microscopy must normally be used. Some older publica ...

Sverdlovsk Oblast
Sverdlovsk Oblast ( rus, Свердловская область, Sverdlovskaya oblast) is a federal subject (an oblast) of Russia located in the Ural Federal District. Its administrative center is the city of Yekaterinburg, formerly known as Sverdlovsk. Its population is 4,297,747 (according to the 2010 Census). Geography Most of the oblast is spread over the eastern slopes of the Middle and North Urals and the Western Siberian Plain. Only in the southwest does the oblast stretch onto the western slopes of the Ural Mountains. The highest mountains all rise in the North Urals, Konzhakovsky Kamen at and Denezhkin Kamen at . The Middle Urals is mostly hilly country with no discernible peaks; the mean elevation is closer to above sea level. Principal rivers include the Tavda, the Tura, the Chusovaya, and the Ufa, the latter two being tributaries of the Kama. Sverdlovsk Oblast borders with, clockwise from the west, Perm Krai, the Komi Republic, Khanty–Mansi Autonomous Okru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Open-pit
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 (geology), rock or minerals from the earth from an open-air pit, sometimes known as a Borrow pit, 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 t ...

List Of Gulag Camps
The list below, enumerates the selected sites of the Soviet forced labor camps (known in Russian as the "corrective labor camps") of the Gulag. Most of them served mining, construction, and timber works. It is estimated that for most of its existence, the Gulag system consisted of over 30,000 camps, divided into three categories according to the number of prisoners held. The largest camps consisted of more than 25,000 prisoners each, medium size camps held from 5,000 to 25,000 inmates, and the smallest, but most numerous labor camps operated with less than 5,000 people each. Even this incomplete list can give a fair idea of the scale of forced labor in the USSR. List history Initially, the list of Gulag penal labor camps in the USSR was created in Poland from the personal accounts of labor camp detainees of Polish citizenship. It was compiled by the government of Poland for the purpose of regulation and future financial compensation for World War II victims, and published in a decre ...

Prisoner-of-war Camp
A prisoner-of-war camp (often abbreviated as POW camp) is a site for the containment of enemy fighters captured by a belligerent power in time of war. There are significant differences among POW camps, internment camps, and military prisons. Purpose-built prisoner-of-war camps appeared at Norman Cross in England in 1797 during the French Revolutionary Wars and HM Prison Dartmoor, constructed during the Napoleonic Wars, and they have been in use in all the main conflicts of the last 200 years. The main camps are used for marines, sailors, soldiers, and more recently, airmen of an enemy power who have been captured by a belligerent power during or immediately after an armed conflict. Civilians, such as Merchant navy, merchant mariners and war correspondents, have also been imprisoned in some conflicts. With the adoption of the Geneva Convention on Prisoners of War (1929), Geneva Convention on the Prisoners of War in 1929, later superseded by the Third Geneva Convention, prisoner-o ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
