A miner was repairing a personnel carrier while standing between a rib and the carrier. A section of the adjacent rib corner, weighing approximately 1,250 pounds, fell on the miner causing severe injuries. The miner died 16 days later.

Best Practices: 

  1. Make roof control plans that contain safety requirements. Rib support may be necessary when the mining height increases, when rock partings are present in the rib, or when encountering deeper cover.
  2. Mine operators must control roof and rib conditions. Plans should include provisions requiring that mine operators recognize adverse or changing roof and rib conditions.
  3. Be aware of potential hazards when working or traveling near mine ribs, especially when geologic conditions could cause rib hazards.
  4. Pay attention to deteriorating roof and rib conditions when working in, or traveling through, older areas of mines.
  5. Avoid areas of close clearance between ribs and equipment.
  6. Train all miners to conduct thorough examinations of the roof, face and ribs where miners will be working and traveling.
  7. Conduct frequent examinations in areas where mine conditions change.
  8. Correct all hazardous conditions before allowing miners to work or travel near them.
  9. Adequately support loose ribs or scale loose rib material from a safe location using a bar of suitable length and design.
  10. Install rib bolts on cycle, with adequate surface coverage, and in a consistent pattern.

This is the 26th fatality reported in 2019, and the third fatality classified as “Fall of Face, Rib, Pillar or Highwall.”

2019 Fatality #24 / Coal #11

renewcomerLeave a comment

On December 23, 2019, a miner was fatally injured while attempting to remove a splice pin from a 72-inch mainline conveyor belt splice.  A belt clamp and racket-style chain come along failed, releasing stored energy and causing the belt to shift upward and pin the miner against the frame of the belt tailpiece.

Best Practices: 

  • Identify, isolate, and control stored energy: mechanical, electrical, hydraulic and gravitational. Relieve belt tension by releasing the energy at the take-up/belt storage system.
  • Check your environment. Always be aware of an object in your work location that could move if stored energy is released.
  • Check your equipment. Ensure belt clamps and other blocking equipment are substantial and properly rated for preventing conveyor belt movement.
  • Securely install, anchor, inspect, and test blocking equipment to ensure that it is able to prevent movement.
  • Conduct complete and thorough examinations from safe locations to identify hazards and items needing maintenance or repair.
  • Ensure miners are trained on safe work procedures. Develop step-by-step procedures and review them with all miners before they perform non-routine maintenance tasks such as adding or removing conveyor belt.
  • Properly block belts to secure components against motion.
  • De-energize electrical power and lock and tag the visual disconnect before beginning a belt splice.
  • Never use the start and stop controls (belt switches). This switch does not disconnect the power conductors.
  • Lock out and tag out disconnecting devices. Only the person who installed them can remove the lock and tag, and only after completing the work.
  • Talk to your coworkers. After the splice has been completed and before removing your lock and tag, ensure everyone is clear of the conveyor belt and communicate to others that you will be restarting the belt.
