Superstition Crushing L.L.C. · Struck by falling object
While working near the jaw crusher a rock fell and hit the miner a glancing blow to the left shoulder. The primary contributing factor was the miners location - too close to the jaw. After a trip to the clinic on his way home, it was determined that the only damage was bruising. The miner returned to work the next day to regular duty. There was no time loss, but he saw a doctor.
