Rocanville, Sask. — Twenty miners who sought refuge in a safe area at Potash Corp. of Saskatchewan Inc.’s Rocanville potash mine in Saskatchewan last week were safely evacuated. The miners moved to a refuge area in the mine after fire broke out on a cable spool at 1:56 a.m. CST Sept. 25. At the time, there were 29 miners underground; nine were able to make it to the surface. The fire was put out around 1 p.m. CST, and the remaining miners were able to return to the surface on Tuesday evening, about 18 hours after the fire started. There were no injuries. PotashCorp said the mine would likely resume production sometime on Sept. 26.
