Open-Pit Mining | Method and Process | Epiroc US
Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.

Opencast Mining (Quarrying): Methods, Advantages & Disadvantages
Glory hole mining is a method where the mineral is excavated in small open pits but is transported to the surface through underground excavations and transport system. Nearly 70% of the mineral production in the world comes by opencast mining and in India this method of mining accounts for nearly 75% of our mineral output.
Beginners Guide to Stope Mining
The open stoping mining method can be used in projects that do not require artificial support and can support its own weight and remain stable. There are several types of open stope mining, including sublevel stoping and overhand stoping, in which the ore is promptly removed after it is mined and the stope can remain open. ...

Open-Pit Mining Definition | Anglo American
Open-pit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels. This surface mining technique is used when mineral or ore deposits are found relatively close to the surface of the earth. Open-pits are sometimes called 'quarries' when they produce building materials ...
2. Mining Methods

Mining Methods
Open pit mining is a process of fully opening an ore body and excavating it from the topographic surface (Fig. 2.1).The open pit is mined using steps, called benches (Fig. 2.1a). A bench is a horizontal slice of an open pit which is mined as a unit.
