Feb 01, 2013#0183;#32;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 finished.
Sep 06, 2006#0183;#32;What is the difference between an opencast mine and an open pit mine? open pit and open cast mines are basically the same things. they refer to any mining for minerals located near the surface and extracted from an open pit. an example would be a quarry. 0 0.
In practice, this difference manifests itself in the type of operation; opencast quarries (termed opencast mines) clearly differ from underground mining, which is never described as quarrying (at least in the UK). Mining, at least from a geological perspective, is typically far more complex.
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
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.
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...

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.

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.
because opencast mining doesnt require shafts and tunnels to be built unlike other approaches such as deep mining. it is on the surface so transportation costs from underground to ground level do
Openpit Mining: Removing ore to leave a crater. 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.
Difference between surface and subsurface mining. Pros and Cons classified as open pit, opencast, quarrying or underground. An open pit mine is the mine to exploit the deposits which are outcropping to the surface, or those which are confined to a shallow depth, and the waste Open Cast Mining/Strip Mining Introduction
Aug 22, 2017#0183;#32;Theres an obvious distinction between open pit mines and underground mines that leads to the main differences from the miners perspectives. Open pit mines allow for heavy machinery and workers to do their jobs in the open and usually with more maneuverability.
Underground mining only involves a small surface disturbance area and only the coal seam is mined, thereby leading to significantly lower impacts than an open cut mine. Due to the limited surface activity there is a dramatic reduction in impacts from dust, lighting and noise, whilst retaining the many benefits from a coal mining operation, including jobs, community investment, and support for local suppliers.
