Advantages And Disadvantages Of Surface Mining | ipl
Surface mines offer advantages and disadvantages when compared to underground mining. Amongst the advantages are that it is cheaper, can recover more of the resource (usually up to within the mining excavation), is safer and can use larger-scale mining equipment offering higher production rates. Disadvantages include its high visibility ...

· Subsurface mining is the removal of deposits from the earth by drilling underneath layers of rock and dirt. These deposits are difficult to reach from the surface and require the drilling of vertical or horizontal shafts for access. Solid subsurface resources are often blasted out of rock with explosives.
· In view of these limitations, adopting the principles of ground penetrating radar (GPR) presents a potential geophysical approach that could overcome all the disadvantages of the current method used in subsurface gas monitoring. Comas and Slater7 applied this technology in peatland studies and reported considerable success.
· Pro: Subsurface Mining is a faster method of mining than 60% of mining in the US; it''s cheaper. Con: Dangerous; explosions/fires, mine collapses, fumes. Processing is usually done one site before heading to the plant. This method of processing is more time efficient but seems costly. Processing usually includes crushing and flotation techniques.
Question 21 of 25 4.0/ 4.0 Points The disadvantages of using wind energy to generate electricity include all of the following except A.windmills kill birds. B.generation of sulfur dioxide, carbon dioxide, and nitrogen oxides. C gradation of an area''s scenic beauty. D.tying up large parcels of land.
· Mining disadvantages. Water pollution in the mining zone is usually found. Most mining areas lead to the drainage of acidic rock. Illegal mining has a negative impact on biodiversity. Mining affects aquatic organisms (microorganisms) and also affects terrestrial organisms (vegetation, animals) etc. mining effects.
· Mountaintop removal has both advantages and disadvantages. The key here is to continue the discussion in hopes that, one day, the government, coal companies and residents in mining areas can enjoy the pros without experiencing a lot of the cons.
Longwall Mining A more efficient way to remove coal from a Figure 8 Heavy equipment, like the subsurface seam is to use a method called longwall mining. In rotating shearer of the longwall min- longwall mining, a machine called a shearer moves back and forth ing system shown here, is used to across the face of a coal seam.

Science in Mining Introduction: There is a lot of physical strengths involved in mining. However, before people mine any landscape, they need people like: geologists, mathematicians, biologists, engineers, economists, geographers, and other experts from narrower areas (mineralogists, geophysicists& petrologists) to plan & acknowledge all of the outcomes of their decisions (how mining is going ...
· The Pros of Strip Mining. 1. High Recovery Rate. Other forms of mining do not guarantee the same rate of return as strip mining does. Materials are recovered at a rate of up to 90 percent during strip mining, which is a much higher recovery rate than most forms of mining can promise. Tunnel mining, for instance, only offers users a potential ...
Subsurface mining has less impact on the surrounding landscapes. Subsurface mining offers more employment opportunities. Identify the advantages and disadvantages of coal as a fossil fuel.
· The disadvantages of mining include harm to air pollution, water pollution, loss of usable land, destruction of animal habitat, and harm to local communities and the miners themselves. While mining produces the resources needed for fuel, electronics, and other items as well as jobs, companies often don''t factor the harm mining can do into ...

Surface mining techniques don''t work for extracting all valuable geologic resources. Diamonds and most metal ores, including gold, require extensive subsurface mines to access the rocks with these resources in them. Subsurface mines are probably what you envision when you think of mining: systems of tunnels and vertical shafts with elevators to take miners underground […]
