## Narrative

Miners were rehab bolting in P14/ vent crosscut. They were cleaning up to do additional bolting when they noticed the ground starting to move. They backed out and ""flagged off"" the entry. Shortly after, the roof caved in above the anchor zone. Ventilation was not interrupted. MSHA was on sight and issued no citations.
