Abstract
The robust control over open pit mining is validated. It is shown that the current coupling of production systems based on equality of averaged capacities of mining and transportation equipment ensures no operational stability in an open pit mine. The article presents an optimization model and the modeling procedure for scheduling equipment repair halts such that to gain sustainable productivity due to uniformly distributed capacity of operational shoveling and haulage equipment. The authors have set stability limits, which imparts robustness to a controlled system and moves management to a new level.
