Hunedoara Steel Works
The Hunedoara steel works, formally ArcelorMittal Hunedoara and formerly the Hunedoara Ironworks ( ro, Uzinele de Fier Hunedoara), Hunedoara Steel Works (''Combinatul Siderurgic Hunedoara''), Siderurgica Hunedoara and Mittal Steel, is a steel mill in the Transylvanian city of Hunedoara, Romania. History Beginnings in Austria-Hungary Several factors led to the establishment of the works, which were located in an area that was then part of Austria-Hungary: late 19th-century technological development that resulted in increased steel production through new techniques, spurred by the serious need of metal for the Austro-Hungarian Army; the aged and unprofitable methods used by the area's iron workshops; the building of a railroad; and the enlargement of the market due to increased metal consumption in Transylvania's mechanical plants.

Hunedoara (5)
Hunedoara (; german: Eisenmarkt; hu, Vajdahunyad ) is a city in Hunedoara County, Transylvania, Romania. It is located in southwestern Transylvania near the Poiana Ruscă Mountains, and administers five villages: Boș (''Bós''), Groș (''Grós''), Hășdat (''Hosdát''; ''Hochstätten''), Peștișu Mare (''Alpestes''), and Răcăștia (''Rákosd''). The city includes the most important Gothic-style secular building in Transylvania: the Hunyad Castle, which is closely connected with the Hunyadi family. The castle was destroyed by fire five times, but underwent many reconstructions from Austro-Hungarian and later Romanian authorities. Besides the castle, the town developed as a production center for iron and a market for the mountain regions nearby. During the 20th century, Hunedoara's population increased to 86,000 inhabitants. The city contained the largest steel works in Romania (until Galați took the lead), but activity gradually diminished after the fall of the Iron Curtain ...

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] |
