Temchenko A. Scientific fundamentals of avaluation and selection of energy saving technology of open-pit mining of iron ore deposits

Thesis is devoted to the elaboration of theoretical fundamentals of mining operation energy saving technology at the iron ore quarries. The basic principle of energy saving theory is substantiated by means of technological techniques of mining operation carrying out at the quarries which provide Integral index minimum of their efficiency which is the sum of consumed energy expenses at the money equivalent and given consumed expenses to one hrivna of commodity production. The substantiation of energy saving mining operation technology which is based on great system theory consists of technological equipment choice, modes of work and schemes of its functioning for the whole complex and at certain conditions which supply the minimum of the accepted criterium of evaluation.To increase combine work efficiency as whole their productive powers are optimized by means of non-linear programming model.Transferring to the energy supplying technology at the quarries of the Kriviy Rih basin is proposed which will provide the lower energy capacity and smaller financial expenses.
