Description:A 42 year old male trona miner died from injuries received when the roof of a cave fell on him. The victim was part of an eight man team removing styrofoam stoppings with a two-man 6' drill auger to establish ventilation in preparation to drive a bleeder system to the south of the area. As he and his co-worker were moving into place to remove the stopping, a slab dropped from the ceiling, striking the victim and knocking him down. A co-worker that was in the process of being relieved was struck by falling rock which pinned his legs to the floor. Other workers who were waiting their turn at the operation called for help and crew members quickly began trying to remove the injured workers from the debris. Within a few minutes after the cave-in, porta-power devices and a mechanical jack were brought in to remove debris, and the victim was freed about 50 minutes after the incident occurred. CPR was started after the victim had been removed from under the slab and was continued until he had been brought to ground surface approximately 30 minutes after having been freed from the debris. He was pronounced dead at the scene, from thoracic trauma due to crushing impact to the chest. Employers may be able to minimize the potential for occurrence of this type of incident through the following precautions: 1. Increase the size and strength of pillars and roof bolts used to secure ceilings in tunnels. 2. Install temporary supports to supplement permanent braces when removing or replacing stoppings. 3. Enhance safety briefings and training programs to place more emphasis on preventions and hazards of potential roof cave-ins.
