What is Open Cut Mining? How does it work? What jobs are there?

Open cut mining, also known as open-pit or open-cast mining, is a method employed to extract valuable minerals or rocks from the earth. This type of mining is characterised by the creation of a large visible pit or hole in the ground, as opposed to tunnelling into the earth, which is typical of other forms of mining.
