On Tuesday, December 11, 2018, a 38-year-old miner was fatally injured at a surface coal mine.  The miner was operating a front-end loader to move shot rock near the toe of a 63-foot-high highwall.  A large portion of the highwall collapsed onto the front-end loader, crushing the operator cab and fatally injuring the miner.
Best Practices: 

  • Safely examine highwalls from as many perspectives as possible (bottom, sides, and top/crest).  Look for signs of cracking and other geologic features that could lead to instability and secure or remove hazardous conditions.  Conduct additional examinations as ground conditions warrant, especially during periods of changing weather conditions.
  • Follow the approved ground control plan at all times to ensure the safe control of highwalls.
  • Use mining methods that ensure highwall stability and safe working conditions and do not excavate the base of the highwall.
  • Train all miners to recognize hazardous highwall conditions.
  • Operate mobile equipment perpendicular to the highwall or with the operator’s cab positioned away from the highwall.  Ensure that miners work, travel, and operate mining equipment at safe distances from the highwall.
  • Use proper blasting techniques for forming highwalls and thoroughly examine the highwall after each blasting operation.

On Wednesday, October 17, 2018, a 33-year-old auger helper with 3 days of total surface mining experience received fatal injuries during auger mining activities. The victim was attempting to move a section of auger steel by using the onboard crane when he was struck in the chest.
Best Practices: 

  • Maintain equipment in safe operating condition. Excessive pressure in a hydraulic circuit can drastically alter the control of booms, etc., creating serious hazards.
  • Establish policies and procedures for auger mining including, safe work procedures for removing auger steel from the auger tray.
  • Task train miners to recognize all potential hazards and understand safe job procedures before beginning work.
  • Monitor personnel routinely to ensure safe work procedures are being followed. Unauthorized persons should be kept clear of the work area.
  • Do not place yourself in a position that exposes you to hazards. Stand clear of suspended loads having the potential of becoming off-balanced while being moved.
