What is subsurface mining? Mining: There are many useful rocks and minerals found on or below the surface of the Earth. Mining is the way that humans extract these resources. There are several ...
Mining processes accumulate a large amount of overburden that can eventually bury or pollute waterways Mining resources are used in the construction of roads and buildings The mining process depends on the renewable resources found in the Earth''s lithosphere Health hazards, oil spills, and soil degradation are all side effects of mining.
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 largerscale mining equipment offering higher production rates.
Subsurface Mining. When mineral ores are too deep to get at with the surface mining techniques, subsurface mining methods are used instead. An advantage of subsurface mining is that it disturbs much less land than surface mining. In fact, it disturbs less than onetenth the amount of land as surface mining.

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 [.]

Environmental Impacts Laws Details about how the topsoil will be affected and how it will be replaced must be stated before mining begins. All affected water must be processed and cleaned before leaving the mining site. Procedures for public notice, public participation and
Open pit mining does offer some advantages over traditional deep shaft mining. Pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly. The working conditions are safer for the miners because there is no risk of cave in or toxic gas. Open pit mining .
Surface mining, including strip mining, openpit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.
