A driller and offsider were preparing to move a drill rig to a new hole, however the jump-up stand and rod rack were interacting. The drill rods were moved from the rod rack up against a wall to allow the rod rack to move.
While the driller was positioning the rod rack, the offsider was using timber to level the rig. During this process the leg of the rod rack made contact with the drill rods positioned on the wall behind. As a result, the 13 drill rods where knocked over and fell onto the jump-up stand and onto the ground. The offsider was also hit by the rods. The offsider suffered bumps and contusions to his wrist and leg.
Recommendations to industry: Mine operators should:
- have procedures for the movement of drills that consider rod management
- conduct worker training in hazard identification that should include those hazards presented by gravity
- have fit-for-purpose drill rod handling equipment.
