## Narrative

Employee climbed into the locked-out longwall pan line, under the protection of a shield, to relieve the ranging arm hydraulic pressure buildup so a broken cutter shaft could be safely removed. A rock fell from the top in front of the shield tip, deflected off the shearer drum, and struck employee in the shin.
