Moroz S. Efficiency of a capital investment in updating quarry of a vehicle of the ore enterprises.

The thesis is devoted to the decision of the important task of updating of a fixed capital of a vehicle of ore dressing combines on production ore of raw material. In work is determined and the system of an estimation of a condition, replaceable productivity, deterioration quarry of a high-power vehicle is constructed. Is revealed and the influence of a deterioration vehicles on parameters of their use is proved. The parameters and analytical dependencies connected to the forecast of volumes of transportation in conditions of constant deterioration of machines are developed. The methodical recommendations by definition of productivity quarry vehicles are offered. The problem of definition of volumes of financing of a capital investment for updating park vehicles is investigated. The structure of the economic mechanism of an estimation of efficiency of capital investments in updating park of machines is determined. The laws of change of a level of expenses are investigated depending on volume of transportation and in a complex with gradual deterioration vehicles. The basic results of researches have found practical realization and introduction on Poltava and Оrdjonikidze ore dressing combines.
