Strip Mining :- Stripping or strip mining is the evacuation of overburden or waste materials from open-pit surface mines. The procedure includes machines, for example, stripping scoops, basin wheel excavators, or drag lines to strip away the stone and reveal the profitable metal that is being mined.
Aug 29, 2015· List of Pros of Strip Mining. 1. It is much more efficient compared to underground mining. Those who advocate for strip mining believe that the recovery rate of materials is higher using the method. It is estimated that about 80 to 90% of the material can be recovered compared to the 50% recovered using tunnel mining.
There are five basic types of surface mining, including open-pit mining, strip mining, dredging, mountaintop removal, and high wall mining. All of these methods remove the waste material or the overburden, which is above the desired resource. Often, surface mining is preferred over underground mining, or subsurface mining, for numerous reasons.
Opencast mining is also known as open-put mining, open-cut mining, surface mining and also as strip mining, the later term being commonly used in the U.S.A. for opencast mining of coal. The overburden and the mineral, coal, are excavated in long strips of a few metres thickness and hence the operations are termed strip mining.
6. Stripping ratio . The main factor in designing a n open pit mine, which largely determines the cost of mining, is the stripping ratio.. Stripping is the removal of waste rock from above and around the orebody. Stripping ratio is defined as the tonnage of waste rock to be mined, divided by the tonnage of ore to be mined from the pit.
Apr 11, 2020· Regarding this, what are the advantages and disadvantages of surface and underground 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 …
May 19, 2014· Strip mining is a type of mining that takes place relatively close to the earth's surface. The process involves removing layers of soil and rock to expose valuable minerals. The minerals are then excavated and sold. Strip mining can destroy land and landscapes. Not aesthetically pleasing to the eye.
Disadvantages of open pit mining. One of the main disadvantages of this type of mining operation is the environmental impact it causes. Since cyanide, mercury and sulfuric acid are used to remove the wastewater, groundwater and air are contaminated as toxic dust . This is absorbed by animals and plants.
Disadvantages of open pit mining. However, disadvantages when compared to Underground Mining also exist: Very large amounts of waste rock are mined. This creates costs as well as environmental issues with waste rock disposal; Major disruption of surface: pit footprint, waste dumps. High visual impact, especially strip mining.
Nov 29, 2017· Mining thesis There are several pros and cons of mining including :- PROS Mining helps us to extract important and useful metallic ores, which we can use in our daily life for our own comfort to make useful commodities . CONS Because of mining we tend to cause soil erosion as after mining extraction is done, we don't re-assemble the soil particles again as due to intense mining activities ...
Strip mining is considered very harmful to the environment. Proponents of strip mining cite its better efficiency, cost, and safety as compared with traditional underground mining techniques. The recovery rate of materials is higher with strip mining, with approximately 80% to 90% of the material being recovered, as opposed to only approximately 50% with tunnel mining.
May 27, 2020· 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 can be accomplished by the following main methods: Open-pit Mining: Removing ore to leave a crater. Quarrying: An open-pit mine for construction materials. Strip Mining: Ore is removed in parallel strips. Mountaintop Removal: Top of a mountain is blasted to remove deep ore. Dredging: Ore is removed from a river bottom. The main methods of underground mining are:

Strip mining is only practical when the ore body to be excavated is relatively near the surface.
Jul 20, 2016· Auger mining is a mining method that recovers coal or other minerals from under the highwall when the ultimate stripping ratio has been achieved in open cast mining operations or Auger mining refers to a method for recovering coal from thin seams, 0.6 to 2.4m thick, beyond a highwall produced by conventional open cast or strip mining (area ...
Feb 13, 2016· Shallow mineral or coal deposits can be economically mined by open-pit or strip mines. However, with deeper mineral or coal deposits it becomes very costly to remove a great deal of overburden in these kinds of settings. So, in these cases underground mining is more cost effective. The downside is that human health and safety are at greater ...
