opencast mining selection

Opencast Mining - an overview ScienceDirect Topics

The open pit or open cast mining method is the obvious choice for a property with a wide area of mineralization exposed or existing close to the surface and continuing to greater depths. The open pit exposes the orebody from the surface by separate removal of ore and associated waste rocks. It is the most economic option for a deposit up to that depth where the economic ratio of ore and waste ...

Opencast Mining (Quarrying): Methods, Advantages ...

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. 2. Methods of Quarrying: ADVERTISEMENTS: The operation of removing ...
