Abstract

The most important parameters, defining value of expenses in opencast and underground development of ore deposits are revealed. Regularities of varying the expenses for opencast and underground mining operations are determined. The formula for calculation of total cost of ore mining depending on the stage of mining technology is proposed. Efficiency of usage of economical and mathematical simulation of different conditions in combined development of deposit for determination of quarry depth in opencast and underground mining is proved.

keywords Quarry depth, expenses for quarry development, cost of ore mining, optimal depth of opencast rocks.
