how to feel about strip mining - quora,mining companies are made to record the habit where they want to mine so when the have removed all of the resources the are meant to put back the dirt the have dug up that has no value and then replant the habitat that was there before the starting mining but so far no strip mine has actually removed all the resources yet so they haven't had to do anything as yet because nearly all strip mines have so much resources that the could easily continue to mine for decades. some strip mines.strip mining | britannica,strip mining, removal of soil and rock (overburden) above a layer or seam (particularly coal), followed by the removal of the exposed mineral. the common strip-mining techniques are classified as area mining or contour mining on the basis of the deposit geometry and type. the cycle of operations for both techniques consists of vegetation clearing, soil removal, drilling and blasting of overburden (if needed),.impact on birds of tar sands boreal forest - pembina,† tar sands mining causes bird habitat loss: the projected strip-mining of 740,000 acres (300,000 hectares) of forests and wetlands in the tar sands will result in the loss of breeding habitat for between 480,000 and 3.6 million adult birds. the corresponding impact on breeding will mean a loss of 4.8 million to 36 million young birds over.minerals and mining - weebly,mining and the environment • mining has an impact because minerals are removed from the earth by undergroundorsurface excavations. • the impact depends on the land, the water, the depth of mineral, the amount removed, method used, soil type, and surrounding rock..

an example is strip mining, which removes the vegetation from an area, making the area more susceptible to erosion. ein-2.l. describe ecological and economic impacts of natural resource extraction through mining. ein-2.l.1. mining wastes include the soil and rocks that are moved to gain access to the ore and the waste, called slag and tailings,7 effects of mining and processing of mineral resources on,some of the major environmental effects of mining and processing of mineral resources are as follows: 1. pollution 2. destruction of land 3. subsidence 4. noise 5. energy 6. impact on the biological environment 7. long-term supplies of mineral resources.
it accounts for a small fraction of the oil extracted from the athabasca tar sands. most of it comes from a process that looks like this: and like this: gosh, you know what that looks like? mining.,5 pros and cons of strip mining | flow psychology,materials such as coal and tar sand are located relatively near the surface of the earth. the method to recover such materials is called strip mining, a form of surface mining where surface vegetation, soil and rocks are removed in strips and often times together with controlled explosions in order to make the removal process more efficient.
mining companies extract bitumen through two standard, destructive methods. strip mining – traditional operations clear-cut trees and brush, and then strip top soil and clay to access the layers of oil sand beneath. the process involves massive trucks and and earth movers to extract 1 to 20% bitumen by total volume. once filtered, the upgraded crude goes directly to refineries where it becomes,5.1.1: types of fossil fuels and formation - biology,thus, injections of steam and solvent or mining of the tar sands for later processing can be used to extract the tar from the sands. (see related information about strip mining with respect to coal in mining, processing, and generating electricity.) alberta, canada is known to have the largest reserves of tar sands in the world.
the emissions from the average tar sands operation are up to 15% higher than in standard crude oil processing procedures. this increase is due to the depth of the oil in tar sands and the separation process that is required to separate the bitumen from the other components. 3. dependence on tar sands may just prolong the inevitable.,what is the difference between strip mining and open pit,open-pit mining' refers to a method of extracting rock or minerals from the earth through their removal from an open pit or borrow. although open-pit mining is sometimes mistakenly referred to as 'strip mining', the two methods are different (see above).
types of surface mining. open-pit mining – machines dig holes and remove ores. strip mining – gigantic earthmovers strip away the overburden, and power shovels remove the mineral deposit. contour mining – is used mostly to mine coal on hilly or mountainous terrain. mountaintop removal,chapter 15: geology and nonrenewable mineral resources,surface mining type of resource and topography determines strategy • open-pit mining • strip-mining (horizontal beds) • area strip mining (flat terrain) > dig trench > strip mineral > fill trench with overburden > *leaves spoil banks – highly erodible – *susceptible to chemical weathering and erosion – *restoration difficult (no top soil)

strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. the pits are parallel and adjacent to each other. strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling.,non renewable energy pros & cons flashcards | quizlet,produced: its extracted by strip mining or open pit mining oil,coal,natural gas, oil sand and oil shale how it generates:they burn, heat up water, and that turns a turbine.the turbine spins large magnets inside of large numbers of metal coils and this move the electrons, thus producing electricity.
type of surface mining used where the terrain is flat. an earth mover strips away the overburden, and a power shovel digs a cut to remove the mineral deposit. after removal of the mineral, the trench is filled with overburden, and a new cut is made parallel to the previous one.,is strip mining good or bad? - answers,mining. is strip mining good or bad? asked by wiki user. see answer. top answer. wiki user answered 2011-10-25 21:44:59. its is bad dont you know that.. 0 0 1.

mining. surface mining falls into two categories. open-pit mining is used when a bed of coal is wide and deep. overburden is removed from the top of the ore and digging is continued until the ore is gone. strip mining is the second type of coal mining. this is used when the bed is wide but not deep.,digging deeper: mining methods explained | anglo american,open-pit is one of the most common mining methods used and starts from the earth's surface, maintaining exposure to the surface throughout the extraction period. the excavation usually has stepped sides to ensure the safety of the miners and a wide ramp where equipment can travel, allowing the product to be removed efficiently from the site.
