Abstract
Increasing depths of open-cast mining and the distances of rock material haulage by trucks contribute to the rise in total costs. Open-cut transport is the main source of environmental impact due to high levels of exhaust emissions as well as dusting of the motor road surface and the transported rock mass. These factors make optimization of the transport component a priority. The paper considers the specific features of mining operations in deep open-pits. It is demonstrated that in such conditions the transition to conveyor ore transportation with justification of conditions and parameters for designing of mining systems is an important scientific and practical task. Advantages and disadvantages of the truck and conveyor haulage are analyzed. Conditions that determine safe transition to the conveyor ore transportation are defined using the case of the Kostomuksha open-cast mine. It is proven that justifi-cation of conditions and parameters for the design of the mining systems in construction and operation of a complex conveyor ore transportation system will help to improve the efficiency of transition to the new technology, to ensure proper management of the mining operations during the transition peri-od and to introduce reliable smart technologies for long-term operation of complex mining transport systems in deep open-cast mines.
