Abstract

A model of performance evaluation of supplies development schemes by ramp with the transportation of ore with quarry lifts is suggested in the paper. The construction of the underground mine from the open pit space reduces the construction time and capital investments, ore transportation from the mine with the quarry lifts minimizing operating costs on the rise. These factors can significantly reduce the cost of extracting the ore mass, thereby increasing the effectiveness of mining stocks compared with the traditional way of opening through vertical shafts from the surface. With a small depth of the ore body engineering schemes considered allow to avoid supplies development from the surface and extend the scope of development schemes from the pit area using lifts installed by previous studies.

Keywords

Combined open-underground mining method, engineering schemes, conveyor, skip, the transportation cost.
