We will discuss all the major equipment you will need to start your open pit mining business, what the equipment is used for, and of course, how much it will cost you to acquire each equipment.
Open pit mines are exploited bench-by-bench from the top bench, all the way to the bottom of the pit. There is no way out of it. Diagram A below represents a big final pit (coloured in red) that has no pushbacks. As mentioned above, exploitation of open pits involves completely mining the upper bench in the pit before moving to the bench …
