The mine was shut down as crews battled the blaze that broke out about 10:35 a.m. Monday.
The 318 miners raced to underground refuge stations for safety.
It took around three hours for emergency rescue teams to put out the fire and another few hours for the smoke to clear.
Brad DeLori says all employees were accounted for and there were no reports of injuries.
About 5 p.m., the miners began coming up to the surface.
DeLori says a piece of mobile mining equipment was the cause of the fire.
