Investigator narrative
Two miners working in an underground bin excavation were attempting to level the muckpile by blowing muck down a hole at the brow. They were both tied to retractable fall restraints when the muckpile slid down the repose angle unexpectedly. One employee manually pulled his line and engaged his restraint but the second man was engulfed and suffocated by the finely broken muck.
