On Friday, October 28, 2011, a 47-year old lead blaster and 23-year old blaster helper were killed when the 1-ton truck they were riding was struck and completely covered by fallen rock from a failed highwall. The victims were driving in the pit, past a trackhoe loading coal as they approached their work area. The rock reached approximately 80′ across the 100′ wide pit and struck the trackhoe and a haulage vehicle being loaded at the time of the accident.

Best Practices

  • Train all miners to recognize hazardous highwall conditions.
  • Look, Listen and Evaluate your highwall and pit conditions daily, especially after each rain, freeze, or thaw.
  • Be your own examiner and find hazards before they find you.
  • Maintain adequate lighting to aid in examinations of highwalls and pit during no light or low light situations.
  • Observe and communicate highwall hazards immediately.
  • Insure appropriate action is taken to remove the hazards associated with any anomaly that may appear in the highwall or pit.
  • Ensure that personnel’s work or travel areas and mining systems or equipment are operating are a safe distance from the toe of the highwall.
  • Follow safe job procedures.

Fatality #14 for Metal/Nonmetal Mining 2011

renewcomerLeave a comment

On November 17, 2011, a 26 year-old contract underground miner with 3½ years of experience was seriously injured in a silver mine. He died at a hospital on November 19, 2011. The victim and a coworker were attempting to dislodge muck in a bin excavation when the muck they were standing on started to flow. The victim was wearing a safety harness attached to a self-retracting lanyard; however, the lanyard extended and did not lock before he became engulfed. The other miner was freed immediately, treated, and released from the hospital.

Best Practices
 

  • Wear a safety harness and attach it to a securely anchored lanyard, where there is a danger of falling.
  • In applications where the danger is not limited to a free-fall, do not use lanyards that depend on free-fall speed to lock. Follow the manufacturer’s recommendations.
  • Ensure that persons working on material in bins, silos, hoppers, tanks, and surge piles are properly tied-off, with one line tender per person. No persons should enter the facility until the supply and discharge equipment are locked out.
  • Establish policies and procedures for safely clearing muck in a bin excavation and ensure that persons follow these safe procedures.
  • Ensure that persons are task-trained and understand the hazards associated with the work being performed and the proper use of their personal protective equipment.
