As the name suggests, open pit mining involves mining minerals or ore that can be found near the surface layer of the site. That being said, some quarries can be over 1000 meters deep. This form of mining doesnt require tunnelling into the earth and is a simple method of mining that yields high production rates.
Quarrying: An openpit 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: Room and Pillar Mining: Removing ore, while leaving behind some for roof support.
Open pit mining. Quarry. Underground mining with shaft. Done for those minerals which lie close to the surface of the earth. Used for mining minerals at shallow depths. Minerals which lie at great depths below the surface of the earth. Used where commercially useful minerals are found near the surface.
Expert Answer: Open pit mining. Quarry. Underground mining with shaft. Done for those minerals which lie close to the surface of the earth. Used for mining minerals at shallow depths. Minerals which lie at great depths below the surface of the earth.
What is the difference between openpit mining and underground Open pit mining involves the surface removal of material which lies over the ore deposit, and the extraction of the ore with the use of explosives and excavation...
To me as a mining engineer with many years experience in both types of mining, open cast mining means that the deposit is mined in a series of strips with the overburden from each successive strip moved or cast into the preceding strip. The meth...
Open Cut Mining. There are many differences between open cut and underground mining. When minerals and deposits are found close to the surface and spread across a large distance, the best way to mine is to use the open cut mining method. In this process, the area is cleared of all topsoil and vegetation, this material is stockpiled and used
Differences between open pit and underground mining Main Difference. In surface mining, the ore is accessed directly from the Earth''s surface, and contact is maintained with the surface throughout the operation. Underground or subsurface mining is accomplished with the help of tunnels going into the Earth, and does not occur on the surface. Working Principle
Underground mining uses different underground mining techniques to excavate hard minerals, such as ore which contains, gold, copper, silver zinc. Underground mining not only produces gold, copper amp; silver but also precious gems like diamonds amp; rubies. The advantages of underground mining:
Openpit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Openpit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels. This surface mining technique is used when mineral or ore deposits are
Oct 21, 2017#0183;#32;Overall when compared to other methods, opencut is much safer. Opencut mining is responsible for 65 percent of the raw coal production in New South Wales. Opencut is also a good method for gold and copper. Underground mining. Underground mining occurs underground through the creation of tunnels. These tunnels go deep into the mineral seam.
Apr 21, 2014#0183;#32;The Difference Between Underground Mining And Surface Mining 1. The Difference Between Underground Mining And Surface Mining The process of removal of essential mineral ores or geological substances from soil or sand is called mining. These minerals are of great value and are abundantly available in rocks and earths surface.
Differences between underground mining and open pit mining. Apr 02, 2018#183; The Witwatersrand gold mine in South Africa is an excellent example of underground mining that exploits gold from ancient rocks at depths of up to 4 km underground. What is open pit mining.
Apr 02, 2018#0183;#32;The Witwatersrand gold mine in South Africa is an excellent example of underground mining that exploits gold from ancient rocks at depths of up to 4 km underground. What is open pit mining On the other hand, openpit mining is the most common mining and ranges from very lowpriced minerals to finely disseminated gold deposits.
Open Cut Mining. There are many differences between open cut and underground mining. When minerals and deposits are found close to the surface and spread across a large distance, the best way to mine is to use the open cut mining method. In this process, the area is cleared of all topsoil and vegetation, this material is stockpiled and used later when rehabilitating the area once mining is
Aug 22, 2017#0183;#32;Working underground is usually a hot, noisy, humid, and dark business, but working in an open pit mine can expose workers to weather conditions, which can cause problems as well. Working in the mining industry in any capacity is hard work that demands exceptional concentration and talent in order to stay safe in the environment of heavy materials, heavy equipment, and hard work.
Dec 10, 2012#0183;#32;Open pit mining is just digging a large area like a quarry amp; coal taken out from the pit. Underground mining is where they sink shafts into the ground amp; tunnels run off from that point. Strip mining is a form of surface mining. The ore is close to the surface of the land but has one or more layers of rock and dirt on top of it.

Oct 21, 2017#0183;#32;Both opencut and underground mining is used in modern mining. The approaches are different, and there are advantages to each. Opencut mining. Opencut mining gets its name because thats exactly what this type of mining looks like, a big open pit. This type of mining allows for the extraction of minerals that arent very far under the surface.
Unlike open pit, underground mining requires that you take into account a wide variety of added requirements. These include complex ventilation systems, area and local ground support, and of course finding a consistent, safe, and costeffective way to get your materials to the surface.
In general, underground mining is more expensive than open pit mining as with open pit mining the minerals are found near the surface at a maximum of approximately 200400 meters depth in bulk tonnage.. The mining costs are estimated in a mining companys feasibility study which, when available, can be found on the companys website (often hidden between the news releases).
