Abstract In the production of coal mines, the work of “one ventilation and three preventions ” is a key factor affecting the safety of mine production. After the power failure of the high voltage “double circuit ”of the substation in the mining area of the mine, Dashucun Mine cannot restore the power supply of the local ventilator in time, resulting in the shutdown of the local ventilator in the heading face and the gas accumulation exceeding the limit, which seriously threatens the personal safety. Therefore, in order to improve the stability and reliability of local fan power supply in Dashucun Mine, the research and application of backup power supply technology for local fan in mine are carried out.
