renewcomerLeave a comment

On January 7, 2022, a 35 year-old continuous mining machine (CMM) operator was fatally injured when he was pinned between the remote controlled CMM and the coal rib. 

Best Practices: 

  • Operate equipment from a safe location. Stay out of “Red Zone” areas including pinch points, the CMM turning radius, and areas close to the ribs.
  • Maintain proximity detection systems (PDS) in the approved operating condition.
  • Perform the manufacturer’s recommended static and dynamic tests to assure the PDS is functioning properly. Verify that the shutdown zones are at sufficient distances to stop the CMM before contacting a miner.
  • Wear miner wearable components in accordance with PDS manufacturer’s recommendations so warning lights and sounds can be seen and heard.
  • Develop and implement procedures for tramming, repositioning, cable handling and moving remote controlled CMMs safely.
  • Train miners on the function of PDS.

This is the second fatality reported in 2022, and the first classified as “Machinery.”

On July 21, 2021, a 31 year old millwright with 13 years experience* received fatal injuries at a mine in Wright, WY with 899 employees* while adding a boom extension to a crane.  The miner was working under the boom to remove the boom pins when he was struck by the boom.

Best Practices: 

  • Never perform work under raised machinery or equipment until such machinery or equipment has been securely braced in position, blocked and  secured against motion.  Be alert for hazards that may be created while the work is being performed. 
  • Conduct repairs from a safe location per manufacturer’s recommendations.  Verify the release of all stored energy before initiating repairs.
  • Use a lifting device compatible with the load being lifted and ensure blocking material is competent, substantial, and adequate to support and stabilize the load.  Always use the manufacturer’s safety devices or features to secure components against motion, and secure assemblies that rotate to prevent movement.
  • Establish and discuss safe work procedures before starting any task.  Train miners in safe work procedures and hazard recognition.  Monitor personnel routinely to ensure safe work procedures are being followed.

Additional Information: 

This is the 19th fatality reported in 2021, and the fourth classified as “Machinery.” (*details added by safeminers.com from MSHA data.)

On May 18, 2021, a telehandler at an underground mine with 113 employees and 7 contract employees* was towing a trailer with a diesel pump onboard up an inclined underground roadway when the tow hitch suddenly broke. The trailer rolled down the roadway, striking and fatally injuring a 35 year old* contract laborer with 1 year experience*.

Best Practices: 

  • Use towing hardware (hitches, tow bars, receivers, couplers, pins, pintles, safety chains/cables, etc.) which is properly designed and rated. Before each use, examine towing hardware for wear, cracks and other damage. 
  • Never exceed the recommended maximum towing capacity of a tow vehicle or trailer. Follow the manufacturer’s recommendations and only use equipment designed for towing.
  • Always use properly sized safety chains in conjunction with hitches. Safety chains keep the trailer connected to the tow vehicle in case the other tow hardware fails.
  • Never position yourself directly behind equipment being towed uphill.
  • Establish procedures for safe and proper towing. Train miners to follow these procedures and identify hazards associated with towing.

Additional Information: 

This is the 12th fatality reported in 2021, and the third classified as “Machinery.” (*details added by safeminers.com from MSHA data.)

On March 5, 2021, a 63 year old mine manager* was fatally injured when the excavator he was operating rolled over into a body of water at a sand and gravel mine with 5 employees in Mount Sterling, IL*.

Best Practices: 

  • Construct berms or install guardrails on roadways where a drop-off exists.  Ensure berms and guardrails are at least as high as the mid-axle height of the largest equipment using the roadway.
  • Examine and maintain roadways to prevent slope instability such as over steepened banks, sloughs, and cracking on the roadway and bank.
  • Install locked gates at the entrances of roadways that are infrequently traveled.  Post speed limit signs and install delineators at the edges of roads.
  • Always wear seatbelts when operating mobile equipment.
  • When working near water, wear flotation devices and ensure combination seat belt cutter/window breaker tools are installed in equipment.  See safety alert https://www.msha.gov/news-media/alerts-hazards/mnm-safety-alert-water-related-safety.
  • Train equipment operators in the safe performance of their tasks, potential hazards, and the use of alternative/emergency exits in cabs.  Examine these exits during pre-operational examinations.
