Abstract: Underground power supply system is an indispensable key component of coal mine production, and its operational
effectiveness has a significant impact on mine production. Taking this as a starting point, the design and analysis of underground
power supply monitoring and override trip prevention system were carried out. Combining with specific engineering practice, based
on the analysis of the principle of the override trip prevention system, this paper studied the whole monitoring design, and
analyzed the main functions and operation characteristics of the system one by one.

Key words: mine; power supply system; power supply monitoring; override trip
