Underground mining (hard rock) - Wikipedia

Declines are often started from the side of the high wall of an open cut mine when the ore body is of a payable grade sufficient to support an underground mining operation, but the strip ratio has become too great to support open cast extraction methods. They are also often built and maintained as an emergency safety...

Open-pit mining - Wikipedia

Open-pit, open-cast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Open-pit mines are used when deposits of...

Equipment size effects on open pit mining performance ...

As equipment size increases, key dimensions of the geometry (bench height, for example) need to be modified; these changes may result in less control of dilution. In open pit mines, factors that can affect the degree of dilution can be regarded as deposit-related or mine-related. Table 2 shows these factors. Deposit-related...

Open Pit Mining and Quarrying | Pits & Quarries - TechnoMine

The bench height is usually decided by the economic reach of the mining equipment used in the mine. As a thumb rule, a bench height is equal to the economic bucket height of an excavator (like shovel or loader) plus 3 m. The thickness of the orebody and its dip and the thickness overburden also play a deciding role in the...
