## Narrative

Two bolter operators were re-bolting an area that was breaking up. They had bolted to a simplex jack. They decided to manually remove the jack. While one bolter started to let the jack down the other bolter pulled back on the mesh. At this time a rock fell out of the roof between the roof bolts striking the bolter pulling the mesh back on the legs causing a fracture.
