Abstract

Topicality, concept, principles and tool of the robust control in open pit mineral mining are given. It is shown that each stage of the product quality control must have permissible range of fluctuation for coal properties and loading equipment capacity as well as spatial limits for components of the open pit work area. The goal and capabilities of the robust control is the stable operation of the production system within the set limits and constraints. The article presents methodology and implementation tool for the robust control at open pit coal mines.
