Miners And Stockmen's Steakhouse
A miner is a person who extracts ore, coal, chalk, clay, or other minerals from the earth through mining. There are two senses in which the term is used. In its narrowest sense, a miner is someone who works at the rock face; cutting, blasting, or otherwise working and removing the rock. In a broader sense, a "miner" is anyone working within a mine, not just a worker at the rock face. Renowned as one of the most dangerous jobs in the world - and for good reason. Cave-ins, explosions, toxic air, and extreme temperatures are some of the most perilous hazards observed to take place in underground mining, as well as the overall long-term health effects of underground mining conditions. In some countries, miners lack social guarantees and in case of injury may be left to cope without assistance. In regions with a long mining tradition, many communities have developed cultural traditions and aspects specific to the various regions, in the forms of particular equipment, symbolism, m ...

Health And Environmental Impact Of The Coal Industry
The health and environmental impact of the coal industry includes issues such as land use, waste management, water and air pollution, caused by the coal mining, processing and the use of its products. In addition to atmospheric pollution, coal burning produces hundreds of millions of tons of solid waste products annually, including fly ash, bottom ash, and flue-gas desulfurization sludge, that contain mercury, uranium, thorium, arsenic, and other heavy metals. Coal is the largest contributor to the human-made increase of carbon dioxide in Earth's atmosphere. There are severe health effects caused by burning coal. Worldwide 25 people die early for each terawatt hour of electricity generated by coal, around a thousand times more than nuclear or solar. In addition, there have been many coal mining disasters, although work related coal deaths has declined substantially as safety measures have been enacted and underground mining has given up market share to surface mining ...

Brown Coal
Lignite (derived from Latin ''lignum'' meaning 'wood'), often referred to as brown coal, is a soft, brown, Combustion, combustible sedimentary rock formed from naturally compressed peat. It has a carbon content around 25–35% and is considered the Coal rank, lowest rank of coal due to its relatively low Heat of combustion, heat content. When removed from the ground, it contains a very high amount of moisture, which partially explains its low carbon content. Lignite is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation. Lignite combustion produces less heat for the amount of carbon dioxide and sulfur released than other ranks of coal. As a result, lignite is the most harmful coal to human health. Depending on the source, various toxic heavy metals, including naturally occurring radioactive materials, may be present in lignite and left over in the coal fly ash produced from its combustion, further increasing health risks.

Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly Dolomite (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

East Germany
East Germany, officially known as the German Democratic Republic (GDR), was a country in Central Europe from Foundation of East Germany, its formation on 7 October 1949 until German reunification, its reunification with West Germany (FRG) on 3 October 1990. Until 1989, it was generally viewed as a communist state and described itself as a Socialist state, socialist "workers' and peasants' state". The Economy of East Germany, economy of the country was Central planning, centrally planned and government-owned corporation, state-owned. Although the GDR had to pay substantial war reparations to the Soviets, its economy became the most successful in the Eastern Bloc. Before its establishment, the country's territory was administered and occupied by Soviet forces following the Berlin Declaration (1945), Berlin Declaration abolishing German sovereignty in World War II. The Potsdam Agreement established the Soviet occupation zone in Germany, Soviet-occupied zone, bounded on the east b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electric Power
Electric power is the rate of transfer of electrical energy within a electric circuit, circuit. Its SI unit is the watt, the general unit of power (physics), power, defined as one joule per second. Standard prefixes apply to watts as with other SI units: thousands, millions and billions of watts are called kilowatts, megawatts and gigawatts respectively. In common parlance, electric power is the production and delivery of electrical energy, an essential public utility in much of the world. Electric power is usually produced by electric generators, but can also be supplied by sources such as Electric battery, electric batteries. It is usually supplied to businesses and homes (as domestic mains electricity) by the electric power industry through an electrical grid. Electric power can be delivered over long distances by electric power transmission, transmission lines and used for applications such as Electric motor, motion, Electric light, light or Electric heat, heat with high ...

Mining Engineering
Mining engineering is the extraction of minerals from the ground. It is associated with many other disciplines, such as mineral processing, exploration, excavation, geology, metallurgy, geotechnical engineering and surveying. A mining engineer may manage any phase of mining operations, from exploration and discovery of the mineral resources, through feasibility study, mine design, development of plans, production and operations to mine closure. History of mining engineering From prehistoric times to the present, mining has played a significant role in the existence of the human race. Since the beginning of civilization, people have used stone and ceramics and, later, metals found on or close to the Earth's surface. These were used to manufacture early tools and weapons. For example, high-quality flint found in northern France and southern England were used to set fire and break rock. Flint mines have been found in chalk areas where seams of the stone were followed underground ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Breaker Boy
A breaker boy was a coal-mining worker in the United StatesHindman, Hugh D. ''Child Labor: An American History.'' Armonk, N.Y.: M.E. Sharpe, 2002. and United Kingdom whose job was to separate impurities from coal by hand in a coal breaker. Though boys were primarily children, elderly coal miners who could no longer work in the mines because of age, disease, or accident were sometimes employed as breaker boys. The use of breaker boys began in the mid-1860s. Although public disapproval of the employment of children as breaker boys existed by the mid-1880s, the practice did not end until the early 1920s. Coal breaking Coal came into wide use in the late 1590s in the United Kingdom after the island nation was widely deforested and a ban was placed on the harvesting of wood by Charles I of England, so that forests could be used solely by the Royal Navy.Burke, James.

Winding Engine
A winding engine is a stationary engine used to control a wire rope, cable, for example to power a hoist (mining), mining hoist at a pit head. Electric hoist controllers have replaced proper winding engines in modern mining, but use electric motors that are also traditionally referred to as ''winding engines''. Early winding engines were hand, or more usually Horse engine, horse powered. The first powered winding engines were stationary steam engines. The demand for winding engines was one factor that drove James Watt to develop his rotative beam engine, with its ability continuously to turn a winding drum, rather than the early Reciprocating engine, reciprocating beam engines that were only useful for working pumps. They differ from most other stationary steam engines in that, like a steam locomotive, they need to be able to stop frequently and also reverse. This requires more complex valve gear and other controls than are needed on engines used in mills or to drive pumps. E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
