[0002] The coal mine environment is particularly complex, with flammable and explosive gas and coal dust, so power supply safety is crucial. This requires that the mine power grid must have explosion-proof, dust-proof, waterproof and earthquake-resistant characteristics. The insulation performance of electrical equipment and lines must be good to prevent electrical fires and electrical failures. At the same time, the monitoring system must be able to monitor electrical parameters in real time to detect and handle electrical failures in a timely manner.

[0003] Since mine operations are highly dependent on electricity, the reliability of power supply directly affects the production efficiency of coal mines and the safety of workers. To this end, the mine power grid needs to have sufficient redundancy and fast fault switching mechanisms to ensure that major equipment and key areas can quickly switch to backup power when power problems occur. In addition, regular maintenance and inspections are also important measures to ensure the reliability of the power grid. High-quality power supply is essential to ensure the normal operation of mine equipment and extend the life of equipment. This includes voltage stability, frequency stability and low harmonic pollution.
