Jan 14, 2020· Strip mining is a form of surface mining that is usually employed for the recovery of materials such as coal and tar sand, which are relatively near the surface of the earth. Surface vegetation, soil, and rocks are removed in strips, often in conjunction with controlled explosions, to make removal more efficient.
Open pit mining -- or strip mining -- is an extraction process for ore or fossil fuels that takes place at the surface of a mining site. Worldwide, 40 percent of mining occurs at the surface, according to Greenpeace International. Compared with underground mining, surface mining is much more efficient.
Some say there are advantages to surface mining. The obvious advantage is that it should be safer for mine workers than being in shafts where they can be trapped. There is also a lower cost of recover (since trucks can enter the mine), but there are also many disadvantages. There have been deaths due to surface mining.
Feb 13, 2016· What are the advantages and disadvantages of underground mining? Environmental Science Land and Water Use Mining. 1 Answer Don Mac Feb 13, 2016 Economically a better option in some geological settings, but human safety a major issue. Explanation: Shallow mineral or coal deposits can be economically mined by open-pit or strip mines. ...
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.

Apr 12, 2009· Advantages. Underground mining (as compared to open pit exploitation) allows a mine operation to be largely 'hidden' having only adits or headframes protruding above the surface. This enables the land above the zone of mining to be reclaimed for other uses, after the mining has ceased, so much easier than in the case of an open pit.
Mining is an activity to take out precious natural resource to satisfy humans unending demand. This activity is carried out extensively and has caused major imbalance in our ecology. There are several other industries dependent on mining, hence an...

Sep 24, 2015· 5 Chief Pros and Cons of Strip Mining. Sep 24, 2015 Aug 29, 2015 by Editor in Chief. Surface mining refers to a category of mining where soil and rock overlying the mineral deposit are removed. There are several types of surface mining, and strip mining counts as one of them.
Surface mining is suitable for large, low-grade ore deposits which occur below a thin layer of rock, or alluvial deposits found in sand and riverbeds. Underground mining is used for small, high-grade deposits covered with a thick overburden (soil and rock above the ore), or .
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 .
In the previous topic, we saw which are some of the advantages that can make the surface open pit mining methods superior method compared to the underground mining. However, underground mining has its own advantages. And finally, the ultimate decision to mine from the surface or from underground comes down to the specific characteristics of the deposit. In particular, mineral deposits can ...
The environmental damage caused by surface mining is related to the large amount of surface material that humans remove during mining operations. The environmental effects of surface mining include Habitat destruction Soil erosion Air pollution from dust particulates Pollution (especially from sediments) All surface mining techniques negatively affect the environment, though some methods are ...
Jul 26, 2015· Strip mining is a form of resource collection that involves dirt removal from a very large area to sift through it. Instead of working underground, a pit is created deep in the ground and all work is accomplished on the surface. Here are the pros and cons of strip mining to consider. Strip Mining .
Apr 27, 2015· Historically speaking, underground mining not only saves the mining area's original form but also gives the mining company higher revenues. According to MiningGlobal, longwall mining, a type of underground mining that utilizes a longwall shearer, accounts for 50 percent of coal mines in the world and is much safer than other methods of coal mining.
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
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 ...
