Optimising Open Pit to Underground Cutover: Part Two ...
05/04/2018 · Given that underground mining profits are less dependent on depth there will likely be a point where the marginal profit of the underground exceeds that of the open pit. Using this method the cutover point is the depth at which the marginal profit from the openpit is equal to the marginal profit from the underground.
(PDF) Open Pit Transition Depth Determination Through ...
As open pit mining of a mineral deposit deepens, the cost of extraction may increase up to a threshold where transitioning to mining through underground methods is more profitable.
Openpit Mining
Openpit mining occurs on surface and is generally the cheapest way to extract ore. This is because rock doesn't have to be moved far up hill against gravity, equipment used can be larger than underground, and it doesn't require more expensive features like ventilation, communiions, etc. that underground does.
