Workers now out after being trapped by fire in Manitoba mine
All had been safely brought to the surface by 1:30 p.m. Monday.
The fire broke out at the Vale Inco mine in a piece of equipment called a scoop tram, according to the workers' union.
The flames were contained but a handful of miners spent the night in safe rooms to protect themselves from smoke and gas.
The miners were not injured and are doing fine, said Murray Nychyporuk, president of the United Steelworkers Local 6166.
"For some of them to spend the night and into the morning in a safe is uncomfortable and obviously something you don't want to do. But it's part of the protocol to remain in a safe room until you get the all clear," Nychyporuk said.
A Vale spokesperson said mine operations were expected to be back up and running Monday night.
Vale and the union plan to carry out a joint investigation to determine what went wrong and how to prevent similar incidents from happening in the future.
