Stellarton Surface Coal Mine
The Stellarton Surface Coal Mine is an open pit reclamation coal mine located in Stellarton, Nova Scotia. It is owned and operated by Pioneer Coal Limited. Operations The mine began operations in 1980 and coal is extracted using truck and shovel mining. Coal mining has taken place in this area of Pictou County for more than 400 years, and until the Donkin Mine reopened in 2017, the pit was the only operating coal mine in Nova Scotia. Underground mining previously took place in the area where the Stellarton pit is located and occasionally remnants of the abandoned tunnels from underground mining can be seen on the pit walls. Once coal has been extracted, the surface is restored through reclamation. In 2014 Pioneer Coal applied to modify the "method of extraction" to include explosives, allowing them to blast through of rock to access a seam of coal. The application has raised concerns with the local community. The mine produces about 300,000 tonnes of coal per year. Its princip ...

Underground Mining (soft Rock)
Underground soft-rock mining is a group of underground mining techniques used to extract coal, oil shale, potash, and other minerals or geological materials from sedimentary ("soft") rocks. Because deposits in sedimentary rocks are commonly layered and relatively less hard, the mining methods used differ from those used to mine deposits in igneous or metamorphic rocks (see underground hard-rock mining). Underground mining techniques also differ greatly from those of surface mining. Methods of underground soft rock mining * Longwall mining – A set of longwall mining equipment consists of a coal shearer mounted on a conveyor operating underneath a series of self-advancing hydraulic roof supports. Almost the entire process can be automated. Longwall mining machines are typically 150–250 metres in width and 1.5 to 3 metres high. Longwall miners extract "panels" - rectangular blocks of coal as wide as the face the equipment is installed in, and as long as several kilometres. Powe ...

Coal Mines In Canada
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Surface Mines In Canada
A surface, as the term is most generally used, is the outermost or uppermost layer of a physical object or space. It is the portion or region of the object that can first be perceived by an observer using the senses of sight and touch, and is the portion with which other materials first interact. The surface of an object is more than "a mere geometric solid", but is "filled with, spread over by, or suffused with perceivable qualities such as color and warmth". The concept of surface has been abstracted and formalized in mathematics, specifically in geometry. Depending on the properties on which the emphasis is given, there are several non equivalent such formalizations, that are all called ''surface'', sometimes with some qualifier, such as algebraic surface, smooth surface or fractal surface. The concept of surface and its mathematical abstraction are both widely used in physics, engineering, computer graphics, and many other disciplines, primarily in representing the surfaces ...

Westray Mine
The Westray Mine was a Canadian coal mine in Plymouth, Nova Scotia. Westray was owned and operated by Curragh Resources Incorporated (Curragh Inc.), which obtained both provincial and federal government money to open the mine, and supply the local electric power utility with coal. The mine opened in September 1991, but closed eight months later when it was the site of an underground methane explosion on May 9, 1992, killing all 26 miners working underground at the time. The week-long attempts to rescue the miners were widely followed by national media until it was obvious there would be no survivors. About a week later, the Nova Scotia government ordered a public inquiry to look into what caused one of Canada's deadliest mining disasters, and published its findings in late 1997. The report stated that the mine was mismanaged, miners' safety was ignored, and poor oversight by government regulators led to the disaster. A criminal case against two mine managers went to trial in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trenton Generating Station
__NOTOC__ The Trenton Generating Station or Trenton GS is a 310 MW Canadian thermal generating station located in the town of Trenton, Nova Scotia. The plant is located on the banks of the East River in the town of Trenton. There are a total of six units at the site although not all are operating at the current time. Units 1 and 2 were completed by the Nova Scotia Power Commission (later Nova Scotia Power Corporation and later still NS Power Inc.) by 1952. The third unit came on-line in 1955 and the fourth in 1960. When the 150 MW Unit 5 went into production in 1969, the Trenton plant was the largest single thermal generating station in the Atlantic Provinces at that time. Unit 6 was commissioned in 1991. The initial boilers (Units 1 to 4) were designed to burn coal mined nearby in Pictou County as well as on Cape Breton Island. Units 5 and 6 could burn either coal or Bunker C oil. The current operating units (5 & 6) burn coal or oil and feature two chimneys; one 152 m (500& ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mine Reclamation
Mine reclamation is the process of modifying land that has been mined to ecologically functional or economically usable state. Although the process of mine reclamation occurs once mining is completed, the planning of mine reclamation activities occurs prior to a mine being permitted or started. Mine reclamation creates useful landscapes that meet a variety of goals ranging from the restoration of productive ecosystems to the creation of industrial and municipal resources. In the United States, mine reclamation is a regular part of modern mining practices. Modern mine reclamation reduces the environmental effects of mining. Reclamation processes As part of the life cycle of a surface coal mine, completed mine areas must undergo rehabilitation. When mining ends, operators must restore the land to its approximate original contour (AOC) or leave the land graded and suitable for a “higher and better” post-mining land use (PMLU) that has been approved as part of the original mi ...

The Chronicle Herald
''The Chronicle Herald'' is a broadsheet newspaper published in Halifax, Nova Scotia, Canada owned by SaltWire Network of Halifax. The paper's newsroom staff were locked out of work from January 2016 until August 2017. ''Herald'' management continued to publish using strikebreaker labour, and were accused by the union of refusing to bargain in good faith with the intention of union busting. History Early years Founded in 1874 as ''The Morning Herald'', the paper quickly became one of Halifax's main newspapers. The same company also owned the ''Evening Mail'', which was published in the afternoon. Its main competitors were the ''Chronicle'' in the morning, and the ''Star'' in the afternoon. By 1949 the papers had merged to become ''The Chronicle-Herald'' and ''Mail-Star'' respectively. Graham Dennis era Graham W. Dennis took over as publisher of the newspaper in 1954, at age 26, after the death of his father, senator William Henry Dennis, who in turn had succeeded senator Wil ...

Open-pit Mining
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 or minerals from the earth from an open-air pit, sometimes known as a 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 the ground, then plotting ea ...
