Abstract: The article considers the issue of determining the amount of emergency and technological standby reserve of power supply in coal mines. It is noted that the regulatory documents do not define clearly the procedure for its determination. In this regard, consumers use the simplest coefficient methods (demand coefficient method and utilization method) for calculations. The authors note that the coefficient methods do not allow to correctly determine the amount of emergency and technological standby reserve of power supply, since they do not take into account the technical and organizational possibilities of using consumer regulators, and also do not take into account the specifics of the operation of the equipment when the process is stopped. On the example of one of the coal mines of Kuzbass, the calculation of the amount of emergency and technological standby reserve of power supply using coefficient methods has been performed. As a result, it was found that the methods of the demand and utilization factors give almost identical results. As a conclusion, it was noted that to determine the amount of emergency and technological standby reserve of power supply, the method of the technological schedule should be applied with simulation modeling of the mine’s operating mode after the technological process was stopped.

Key words: coal mines emergency and technological standby reserve power supply methods of calculating electrical loads utilization factor demand coefficient technological schedule method
