Substantiation of Mining-and-Transportation System Type and Parameters for Mining of Ore Deposits in the Conditions of the on the Kola Peninsula

Resumo

The technical approach to selection and substantiation of transportation systems for hard-to-access mineral mining in the Arctic is based on complexing computer-aided modeling and technical-and-economic assessment methods. The features of the transportation system design for mountainous and upland-and-flat terrains are described. The obtained relations of transportation cost and volume make it possible to validate the choice of transportation. In terms of the Partomchorr deposit, it is shown that under conditions of upland-and-flat terrain and minor level difference, it is efficient to use motor vehicles in case of small transportation volume (to 2.4 Mt/yr) and cable-and-belt conveying in case of large volume of transportation. For the Chinglusuai deposit situated in the upland country with large level difference, efficiency of cableway haulage with feasibility of energy recovery is substantiated.
