Open Pit Mining - an overview ScienceDirect Topics

Open-pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow. Figure 8.8. Open-pit mine [16]. Surface mining is usually used to develop coal seams and deposits of many other minerals, but their feasibilities vary with the nature of the body ore.

2021-7-15  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 extractive methods that need tunneling into the earth.

What Is Open-Pit Mining? (with picture) - Info Bloom

The process of open-pit mining is precipitated by the analysis of the area in order to determine the presence of the desired material that may be coal or ore. If it is determined that the desired materials are present in the area, the next step would be to calculate the stripping ratio of the mining process, meaning that even though ore, coal ...
