Openpit Mining Openpit mining, also known as opencast mining, opencut 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 .
Pit mining. Sometimes valuable geologic resources appear at the surface of the Earth but extend deeper into the Earth — sort of a tipoftheiceberg kind of thing. In this situation, pit mining (also called openpit mining) is an option. Pit mining involves digging a large hole to .
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 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.

Oct 02, 2015· This is a very basic idea of how the Open Pit Mining process takes place. This was a very new mine when the footage was shot, and using very small machines.
Determining an optimum long term production schedule is an important part of the planning process of any open pit mine; however, the associated optimization problem is demanding and hard to deal with, as it involves large datasets and multiple hard and soft constraints which makes it a large combinatorial optimization problem. In this paper a procedure has been proposed to apply a relatively ...
The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines are also in operation around the globe. The decision for employing surface mining or underground mining is dependent on the proximity of the ore body to the surface.
