Did you know?
Mines don’t always stick to one method. Shallow deposits are usually mined from the surface using open-pit methods, but once the ore gets deeper, underground mining takes over or both methods are used together.
Smart mining is about knowing when to make the switch.![]()

Underground – The deeper section mined through tunnels when going deeper becomes more efficient.

Well both are used depending on the nature of the ore body, most start with open surface mining and when they mine to certain depths switch to underground : so they switch if mining with the open methods isn’t economically favorable as compared to the underground method.
