With a view to shortening construction time of deep-level copper–pyrite mines and in order to enhance their efficiency in new economic conditions, a new approach to mine design, planning, construction and accelerated commissioning is proposed. This approach includes arrangement of an ore drawing shaft in the immediate vicinity of an ore body, i.e. in the expected mining-induced straining zone in overlaying rocks, and in selection of bottom-up mining sequence. In this manner, it is possible to shorten the mine commissioning period, to reduce borrowed funds for shafting under the project due to the by-production and capitalization of profits, as well as to cut-down the cost of production in the bottom-up mining. The trial of the proposed solutions in terms of a standard deep-lying deposit shows the possibility of reducing the periods of mine construction and commissioning by two to three years.
Participation of G. V. Mikhailova, Nosov Magnitogorsk State Technical University, in this study is highly appreciated.
