Trapped Ontario miners will all be freed after a grueling climb over 10 hours

With main route to the surface blocked trapped miners forced to climb 1,000 meters on ladders to the surface

The 39 miners trapped underground in a north Canadian mine are expected to be freed on Tuesday, after completing a grueling, half-day climb up more than 1,000 meters of ladders to the surface.

Workers at the Totten mine in northern Ontario were trapped deep underground on Sunday after a scoop bucket detached, blocking the mine's main transport shaft.
