Abstract
The theory of the lag modeling approach to optimizing design capacity of an open pit gold mine by the criterion of maximized integrated economic performance over the mine life is given. The geology of Brekchia gold field in the Altai Krai is described, and the open pit mine design is shown. The optimization results on the open pit mine design capacity by the integral criterion of maximum economic indices using the lag modeling approach are given. The influence of the market prices of gold on the optimized design capacity of the open pit mine is analyzed.
