According to relevant information, in recent years, the average coal mine in the country burned 14,452 electric motors a year, requiring only 6.65 million yuan for repairs. If coupled with on duty or the day should be out of coal due to burning out of the motor and not caused by the economic losses, it is even more impressive.
