## Narrative

The miner & drill operator were changing the striker bar on a top hammer drill. After  replacing the striker bar, they stepped away from the assembly at which time the drill operator lowered the drifter onto the head & exited the cab. The miner approached the assembly & proceeded to align the bolts. The assembly shifted causing his hands to slip up & pinch his left thumb.
