Two main types of mines Open pit mining Roughly ten times lower in cost per ton compared to under ground mining Slope stability decide waste/ore ratio With low grades a high production rate is needed Big equipment for high volume production Under ground mining Under ground mines commonly have lower production rate Increased cost to infrastructure and ground support
Jul 31, 2017· Open pit mining is the process of mining a near surface deposit by means of a surface pit excavated using one or more horizontal benches. The term open pit mining is usually used for metallic or non-metallic deposits and sparingly used for bedded deposits like coal.

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments. In-situ mining ...
however, for large-scale open pit mining in particular, the truck and loader" material movement practice is the preferred method of materials handling (Czaplicki, 1992; Ta et al., 2005). Throughout this paper, we consider a loader" to be any type of high productivity excavating equipment, which may include a mining loader, shovel or excavator.

Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
Multiple benches are employed to reach greater depths than normally achieved in area stripping. Open pit mining does not allow for refilling of the coal voidage and because of the thick seams, a permanent depression is left . Open pit mining has been practiced extensively in Germany for the mining of lignite. Open Pit Mining

Mar 13, 2012· What is Opencast Mining• Opencast mining is also known as Open pit mining, Open cut Mining, Surface or Strip Mining.• The coal upto economical depth will be excavated by OC Method.• The current operating depth of OC mines in SCCL is about 200m and SCCL proposed to operate OC mines upto a depth of 420m. Ex: MNG OC II Extension Project.•
Open-pit Mining Open-pit mining, also known as opencast mining, open-cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from .
