Despite collapses, improvement seen at Mont. mine
BILLINGS, Mont. (AP) — The operator of Montana’s only underground coal mine expects to resume full operations this week after being hit with multiple safety citations and two temporary shut-downs following a series of roof collapses.
No one was injured in the four collapses, which occurred between July 18 and Aug. 12 at Signal Peak Energy’s three-year-old Bull Mountain Mine near Roundup.
Mine president John DeMichiei said efforts to put in new supports to shore up damaged sections of roof were almost completed. That will allow workers assigned to repair duties to return to mining early in the week, he said.
