c1810-fatalOn Thursday, December 20, 2018, a mobile bridge carrier (MBC) operator, with 5 years and 21 weeks of mining experience, was fatally injured while operating his detached, remote-controlled machine during the mining process.  As the continuous haulage system pulled forward in preparation of mining, he was crushed between the coal rib and the No. 2 mobile bridge conveyor that was between both mobile bridge carriers.
Best Practices: 

  • Maintain communications between equipment operators of a continuous haulage system prior to starting or tramming any component of the system.
  • Institute and maintain a high level of equipment-specific training for all operators, which includes proper operator positioning during machine operation and also protocols for certain scenarios.
  • Do not position yourself in pinch-point areas while remotely operating equipment.  Ensure that equipment operators remain in the confines of the equipment cab, if equipped, while the machine is running.
  • Always perform thorough pre-operational examinations on mobile equipment to identify any defects that may affect the safe operation of equipment before it is placed into service.
  • Be familiar with the de-energizing switches on your machine and remote-control unit. “Panic-out” at the first sign of a hazardous situation.

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.
