Abstract:

Purpose. To develop the methodology for determining energy consumption of rope vehicles in order to extend the field of its efficient implementation in mining industry.

Methodology. The solution of the tasks was executed in a complex by analyzing the existing approaches of determination of energy consumption in open cast mining, generalizing the possible schemes of cargoes haulage by the rope transport, choosing the single criterion for evaluation of energy required for moving of cargoes and making the algorithm of its calculation.

Findings. Existing methodologies for determining energy efficiency of transport systems of open cast mines have been generalized and systematized, and the most significant factors determining it have been identified.
Algorithm of determination of specific energy consumption of transportation by means of rope systems has been developed and dependence of energy consumption on the inclination angle of the mine working for recommended transport and technological delivery schemes of cargo have been set.

Originality. Dependences of energy consumption on the inclination angle of the mine working of rope transport facilities in opencast mining have been established for the first time and on the basis of this analysis the rational transport and technological schemes have been offered.
Practical value. Recommendations about introduction of the surface rope road in opencast mining have been developed. Use of surface rope roads reduces transport system energy consumption by 30%.
