Great Snaefell Mine
The Great Snaefell Mine, also referred to as the East Snaefell Mine, was a zinc mine located high in the Laxey Valley on the slopes of Snaefell Mountain, in the parish of Lonan, Isle of Man. The mine reached a depth of and is remembered as the scene of the Isle of Man's worst mining disaster in 1897.''Mona's Herald,'' Wednesday, 12 May 1897; Page: 5 History Mining for metals on the Isle of Man probably began as early as the Bronze Age. Early sites have been identified at Langness and at Bradda Head, where copper could be seen outcropping in the cliffs. Snaefell Mine was situated at the eastern foot of Snaefell; the mineral vein was originally discovered in the bed of a stream. The mining sett was 567 acres (229 hectares) in area and was originally a portion of the Great Laxey Mining Company's property. The sett was surrounded by that of the Great Laxey Mining Company and ran parallel with the Great Laxey lodes. At the pit head there was a washing floor, fitted with wash ...

Diameter
In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere. In more modern usage, the length d of a diameter is also called the diameter. In this sense one speaks of diameter rather than diameter (which refers to the line segment itself), because all diameters of a circle or sphere have the same length, this being twice the radius r. :d = 2r \qquad\text\qquad r = \frac. For a convex shape in the plane, the diameter is defined to be the largest distance that can be formed between two opposite parallel lines tangent to its boundary, and the is often defined to be the smallest such distance. Both quantities can be calculated efficiently using rotating calipers. For a curve of constant width such as the Reuleaux triangle, the width and diameter are the same because all ...

Capital (economics)
In economics, capital goods or capital are "those durable produced goods that are in turn used as productive inputs for further production" of goods and services. At the macroeconomic level, "the nation's capital stock includes buildings, equipment, software, and inventories during a given year." A typical example is the machinery used in factories. Capital can be increased by the use of the factors of production, which however excludes certain durable goods like homes and personal automobiles that are not used in the production of saleable goods and services. Adam Smith defined capital as "that part of man's stock which he expects to afford him revenue". In economic models, capital is an input in the production function. The total physical capital at any given moment in time is referred to as the capital stock (not to be confused with the capital stock of a business entity). Capital goods, real capital, or capital assets are already-produced, durable goods or any non-fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Snaefell Mining Company
The Great Snaefell Mining Company was a mining company formed to operate the Great Snaefell Mine on the Isle of Man. History The company was formed with the intention of working the important mining sett in the Parish of Lonan comprising an area of 567 acres, and which was originally a portion of the Great Laxey Mining Company's property.''Manx Sun'', Saturday, February 25, 1871; Page: 9 The mining sett was surrounded by that of the Great Laxey Mining Company, running parallel with the Great Laxey lodes. The mine was originally worked by the Great Laxey Mining Company from 1856 to 1864 following which the Snaefell Mine Company was formed and which went into liquidation in 1870, with the assets of the company offered for sale. The assets were bought for the sum of £4,000 on 27 April 1870 by James Spittal, Henry Bloom Noble, Thomas Wilson and Alfred Adams who formed the Great Snaefell Mining Company in March 1871. The company was a limited liability company, incorporated unde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Noble
Henry Bloom Noble JP (18 June 1816 – 2 May 1903) was a Cumbrian-born philanthropist and businessman who at the time of his death was the richest resident of the Isle of Man. Noble bequeathed a large amount of his vast fortune to the people of the Isle of Man, resulting in numerous civic amenities such as recreation grounds, swimming baths, a library and a hospital.''Mona's Herald.'' Wednesday, 6 May 1903; Page: 7''Isle of Man Examiner,'' Tuesday 28 November 2017. Biography Early life Henry Noble was born in the village of Clifton, Westmorland (now part of Cumbria) on 18 June 1816, the first son of John Noble and Mary (née Bloom). It is said that he came from a poor failed farming family, his father finding work as a customs official. Business Wine & Spirits His first connection with Douglas was due to his association with Alexander Spittall, father of James Spittall, a Douglas advocate. The elder Spittall was a wine and spirits merchant, whose principal place of business wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead Ore
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the group, le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fathoms
A fathom is a unit of length in the imperial and the U.S. customary systems equal to , used especially for measuring the depth of water. The fathom is neither an International Standard (SI) unit, nor an internationally-accepted non-SI unit. Historically, however, it is the most frequently employed maritime measure of depth in the English-speaking world. There are two yards (6 feet) in an imperial fathom. Originally the span of a man's outstretched arms, the size of a fathom has varied slightly depending on whether it was defined as a thousandth of an (Admiralty) nautical mile or as a multiple of the imperial yard. Formerly, the term was used for any of several units of length varying around . Name The name (pronounced ) derives from the Old English word ''fæðm'', cognate to the Danish (via the Vikings) word "favn" meaning embracing arms or a pair of outstretched arms. Cognate maybe also via the Old High German word "fadum" of the same meaning.''Oxford English Dictionary' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shaft Mining
Shaft mining or shaft sinking is the action of excavating a mine shaft from the top down, where there is initially no access to the bottom. Shaft (civil engineering), Shallow shafts, typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining projects. Shaft sinking is one of the most difficult of all mine development methods: restricted space, gravity, groundwater and specialized procedures make the task quite formidable. Shafts may be sunk by conventional drill and blast or mechanised means. Historically, mine shaft sinking has been among the most dangerous of all the mining occupations and the preserve of mining contractors called sinker (mining), sinkers. Today shaft sinking contractors are concentrated in Canada, Germany, China and South Africa. The modern shaft sinking industry is gradually shifting further towards greater mechanisation. Recent innovations in the form of full-face shaft boring (akin to a v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adit
An adit (from Latin ''aditus'', entrance) is an entrance to an underground mine which is horizontal or nearly horizontal, by which the mine can be entered, drained of water, ventilated, and minerals extracted at the lowest convenient level. Adits are also used to explore for mineral veins. Construction Adits are driven into the side of a hill or mountain, and are often used when an ore body is located inside the mountain but above the adjacent valley floor or coastal plain. In cases where the mineral vein outcrops at the surface, the adit may follow the lode or vein until it is worked out, in which case the adit is rarely straight. The use of adits for the extraction of ore is generally called drift mining. Adits can only be driven into a mine where the local topography permits. There will be no opportunity to drive an adit to a mine situated on a large flat plain, for instance. Also if the ground is weak, the cost of shoring up a long adit may outweigh its possible advantage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bucket (machine Part)
A bucket (also called a scoop to qualify shallower designs of tools) is a specialized container attached to a machine, as compared to a bucket adapted for manual use by a human being. It is a bulk material handling component. The bucket has an inner volume as compared to other types of machine attachments like blades or shovels. The bucket could be attached to the lifting hook of a Crane (machine), crane, at the end of the arm of an excavator, excavating machine, to the wires of a dragline excavator, to the arms of a power shovel or a tractor equipped with a backhoe loader or to a Bucket loader, loader, or to a Dredging, dredge. The name "bucket" may have been coined from buckets used in water wheels, or used in water turbines or in similar-looking devices. Purposes Buckets in mechanical engineering can have a distinct quality from the traditional bucket (pail) whose purpose is to contain things. Larger versions of this type of bucket equip bucket trucks to contain human beings, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compressed Air
Compressed air is air kept under a pressure that is greater than atmospheric pressure. Compressed air is an important medium for transfer of energy in industrial processes, and is used for power tools such as air hammers, drills, wrenches, and others, as well as to atomize paint, to operate air cylinders for automation, and can also be used to propel vehicles. Brakes applied by compressed air made large railway trains safer and more efficient to operate. Compressed air brakes are also found on large highway vehicles. Compressed air is used as a breathing gas by underwater divers. It may be carried by the diver in a high pressure diving cylinder, or supplied from the surface at lower pressure through an air line or diver's umbilical. Similar arrangements are used in breathing apparatus used by firefighters, mine rescue workers and industrial workers in hazardous atmospheres. In Europe, 10 percent of all industrial electricity consumption is to produce compressed air—amountin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A View Across The Washing Floors Of The Great Snaefell Mine
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it fro ...
