Narrative

At 3:35/am a roof fall was found in the 1st Right section at a bore hole that had been originally drilled into the mine as a pilot hole for a raise bore. Because the area had been intended for a raise bore, there weren't any truss bolts in that area. The top fell right to the truss bolts on all sides of the fall.
