Open Pit Production Planning

Term production planning in open pit mines in the presence of price uncertainty by m. rahmanpour and m. osanloo .1 mine planning is a multidisciplinary procedure that aims to guarantee the profitability of a mining operation in changing and uncertain conditions. mine plans are normally classified as long-term intermediate-term.

Risk averse approaches in open

Extends over several decades it is clear that open-pit production planning is a risky endeavor. in this work we take a risk-averse approach on tackling uncertainty in the ore-grades. we consider an extended ultimate-pit problem, where extraction and processing decisions have to be taken.

A new algorithm for open pit mine production

Main idea behind the open pit production planning is the maximization of net present value or maximization of the total profit considering physical and economical constraints. when maximizing the net present value, determining ultimate open pit limit and production scheduling are decisive parameters.
