Justification criteria for open pit mine depth and mining/haulage machinery parameters

Abstract

The paper presents results of studies into criteria for joint justification of open pit mine depth and mining/haulage equipment parameters. New indexes of mineral reserves appraisal are obtained, and a classification of mineral reserves by value is proposed. In terms of a specific deposit, the relations are given for prompt determination of shovel bucket and dump truck capacities, and for justification of rational pit depth under conditions of unstable market of mineral reserves.
