SINOPSIS

The present paper is focused on comparison and analysis of two different main fan units (MFUs) for the "Internatsionalnyi" mine from the viewpoint of ensuring energy efficiency of mining equipment. The mathematical models of the two unit systems were created in terms of the MatLab/ Simulink package to analyze the energy efficiency. The results of calculations were compared with the real parameter obtained with the help of instrumental control. Graphical relationships were established between the static pressure, volumetric flow rate, power, and angular speed. The annular power consumption has been computed.
It has been proven that replacement of MFU resulted in a higher reliability of the mine ventilation system. At the same time, it brought about a significant increase in the energy efficiency of the unit due to the more advanced equipment and adequate management system.
