Headframe
A headframe (gallows frame, winding tower, hoist frame,Ernst, Dr.-Ing. Richard (1989). ''Wörterbuch der Industriellen Technik'' (5th ed.). Wiesbaden: Oscar Brandstetter, 1989. pit frame, shafthead frame, headgear, headstock, poppethead) is the structure above an underground mine shaft, built for hoisting machines, people, and materials. Design Modern headframes are made of steel, concrete, or a combination of both. Timber headframes are no longer used in industrialized countries, but are still used in developing countries. Conventionally, steel headframes are used for drum hoists, and concrete headframes are built for friction hoists; but a steel headframe can be used with a friction hoist for a shaft of smaller capacity and depth. Steel headframes A steel headframe is less expensive than a concrete headframe; the tallest steel headframe measures 87 m. Steel headframes are more adaptable to modifications (making any construction errors easier to remedy), and are conside ... [...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 mining 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Con Mine
The Con Mine (1938–2003) was the first gold mine developed in the Northwest Territories, Canada, just south of Yellowknife. The property was staked by Consolidated Mining and Smelting Company of Canada (Cominco) in September 1935 in response to the discovery of visible gold nearby; the name "Con" is an abbreviation of "Consolidated". The advent of winter prevented any prospecting from being conducted, but work in the summer of 1936 led to the discovery of numerous gold veins. The Con Mine entered production in 1938 and ceased operations in 2003. It has produced over of gold from 12,195,585 tons of ore processed. The mine was over deep. Owners of the mine have included Cominco (1938–1986), Nerco Minerals (1986–1993), Miramar Mining Corp. (1993–2008), and Newmont Mining Corp. (2008–present).

South Wales Valleys
The South Wales Valleys () are a group of industrialised peri-urban valleys in South Wales. Most of the valleys run northsouth, roughly parallel to each other. Commonly referred to as "The Valleys" (), they stretch from Carmarthenshire in the west to Monmouthshire in the east; to the edge of the pastoral country of the Vale of Glamorgan and the coastal plain near the cities of Swansea, Cardiff, and Newport. History Until the mid-19th century, the South Wales valleys were sparsely inhabited. The industrialisation of the Valleys occurred in two phases. First, in the second half of the 18th century, the iron industry was established on the northern edge of the Valleys, mainly by English entrepreneurs. This made South Wales the most important part of Britain for ironmaking until the middle of the 19th century. Second, from 1850 until the outbreak of the First World War, the South Wales Coalfield was developed to supply steam coal and anthracite. The South Wales Valleys hosted B ...

Copper Mining
Copper extraction is the multi-stage process of obtaining copper from list of copper ores, its ores. The conversion of copper ores consists of a series of physical, chemical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental law, environmental regulations, and other factors. The copper smelters with the highest production capacity (metric tons of copper yearly) lie in China, Chile, India, Germany, Japan, Peru and Russia. China alone has over half of the world's production capacity and is also the world's largest consumer of refined copper. Precious metals and sulfuric acid are often valuable by-products of copper refining. Arsenic is the main type of impurity found in copper concentrates to enter smelting facilities. There has been an increase in arsenic in copper concentrates over the years since shallow, low-arsenic copper deposits have been progressively depleted. History Prehistory The Old Copper Compl ...
