Abstract
To determine the most energy-intensive components of the production potential of underground enterprises of the iron ore industry in the Kryvyi Rih region. Research of interaction and carrying out of the comparative analysis of the selected constituent elements. To study this task, the methodology of the system approach and methods of system analysis are used to identify energy-intensive elements of a complex production system. A comparative analysis based on the methodology of multifactor regression analysis. The most energy-intensive components at the underground enterprises of the iron ore industry are allocated, according to conceptual provisions concerning administrative processes of consumption of the electric power at the enterprises of the iron ore industry. It is proved that such energy-intensive elements for iron ore enterprises of Kryvbas are skip lifting installations, crushing and sorting factory, drainage installations, ventilation installations. The interaction of the selected system elements of the production system of the iron ore enterprise is shown. The built regression models allowed to study in more detail the energy-intensive components of iron ore enterprises. The conducted comparative analysis allowed to outline the problematic issues regarding the practical application of the simulation results. for w "Guards". It was found that the specific technological processes that occur on the road. "Guards" need to check the constituent factors of influence. In general, the underground enterprises of Kryvbas are characterized by a negative impact on the overall electricity consumption of the factors that characterize the operation of the component of the crushing and sorting plant. On the basis of the analysis of the received models the corresponding administrative decisions concerning extraction of iron ore raw materials at the enterprises of Kryvbas are formed. Relevant quantitative indicators of factors influencing the energy intensity of the components of the production system of iron ore enterprises in Kryvbas were obtained. Negative and positive impact on the total electricity consumption of the components of the production system, namely: skip hoists, crushing and sorting plant, drainage systems, ventilation systems. All the analyzed enterprises are characterized by a negative impact on the total electricity consumption of the component that determines the crushing and sorting plant. It is considered expedient to increase the amount of information space for a more thorough description and determination of the characteristics of energy-intensive components that affect the extraction of iron ore at the enterprises of Kryvbas.
