Abstract

For the mining industry, the key problem is to ensure maximum energy efficiency at each technological stage of mining production, therefore this article is devoted to assessing the results of modeling two different electric drive systems of the main fan unit of the mine from the point of view of ensuring the energy efficiency of the most energy-intensive unit equipment. In 2017, the main fan units were replaced at one of the mines for the extraction of diamond-bearing raw materials. The main reason for the replacement was the depletion of their resource, as well as an increase in the resistance of the mine network, which required an increase in the depression created by the fan. Comparison of the actual operating parameters of the existing electric drive system and the newly installed one can give an idea of the real scale and directions of development of technologies in the field of electric drive. Collection, processing, analysis and comparison of real data on two fans and electric drive systems of domestic and foreign production can contribute to the disclosure and solution of the problems of import substitution of such equipment. To analyze energy efficiency, methods were applied that involve the creation of mathematical models of two systems in the MatLab/Simulink software package, as well as a technical and economic comparison of the two options in terms of energy consumption. Based on the data obtained as a result of modeling for the TAF-36/21.5-1 and VOD-50 fans, graphical dependencies of static pressure, supply and power on the angular speed were built, and the annual electricity consumption was calculated for each option.
