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] |
