Abstract: Over the past four years in the power system of the Kemerovo region there has been a number of major accidents (at the substation 220 kV Uskatskaya, the power line 110 kV Belovskay – Novo-Leninskay), that have led to blackouts of hazardous industrial facilities – coal mines and open pits. These events have demonstrated the vulnerability of the external power supply system of coal enterprises. The absence of standby power sources in most of the mines in the Kemerovo region has led to stopping of essential loads which created a threat of an accident in the coal mines themselves. The paper deals with the problem of low reliability of external power supply of coal enterprises. An overview is given of several major accidents in the power system of the Kemerovo region. The risks of total power blackout of coal mines are described. To reduce the probability of power outages and to increase the level of industrial safety, the authors suggested to conduct technical audits of external power supply networks of coal enterprises. The result of technical audits is the development of an action plan to improve the coal mines power supply reliability.
