renewcomerLeave a comment

On November 11, 2018, a 45-year old Underground Technician with 4 years of experience was killed when the Load-Haul-Dump (LHD) machine he had been operating underground ran over him.

Best Practices

  • Ensure that all braking systems installed on mobile equipment function properly when the engine is operating and when it is shut off.  Do not depend on hydraulic systems to hold mobile equipment in a stationary position
  • Block LHDs against motion by setting the parking brake. Turn the tires toward the rib and lower the bucket onto the floor.  Use wheel chocks when parking mobile equipment.
  • Conduct adequate pre-operational examinations on all self-propelled mobile equipment and promptly correct any defects affecting safety.
  • Before beginning a task, miners should discuss the work procedures, identify all possible hazards, and ensure steps are taken to safely perform the task.

On July 31, 2018, a 62-year old foreman with 40 years of experience, was fatally injured while dismantling a portable crusher. The front-end loader was placing a 20-foot long steel tube onto the screen feed conveyor. The front-end loader operator lowered the bucket and crushed the victim against the conveyor structure.

Best Practices

  • Front-end loader operators must ensure personnel are not near the machine when in operation.
  • Use cranes with appropriate rigging and tag lines to position components.
  • When working near equipment, make eye contact with the equipment operator and directly communicate your intended movements.
  • Wear a reflective vest or clothing while working.
  • Ensure all persons are trained to recognize workplace hazards – specifically, the limited visibility and blind areas inherent to operation of large equipment.
  • Prior to starting the task, train miners on proper maintenance procedures and discuss steps that will be taken to safely perform the job.

Fatality #6 for Coal 2018

renewcomerLeave a comment

On Tuesday, September 11, 2018, a mobile bridge conveyor (MBC) operator, with 8 weeks of mining experience, was fatally injured during the mining process.  The continuous mining machine (CMM) and attached MBCs had been backed out of a completed cut.  While the CMM was being repositioned, it moved the attached MBCs and crushed the victim between his MBC and the coal rib.
Best Practices: 

  • Frequently communicate with other MBC operators before starting or tramming any component of the system.  Always be in a location where other MBC operators can readily see or communicate with you.
  • Install latching emergency stop switches so MBC operators can actuate them to prevent machine movement when they leave the operator’s cab or position.  See PIB No. P11-16 for information on man-in position switches. https://arlweb.msha.gov/regs/complian/PIB/2011/pib11-16.pdf
  • Stay out of MBC Red Zones if the CMM or any of the MBCs are energized.
  • Be familiar with how the de-energizing switches on your machine operate and immediately actuate them the moment a hazard is recognized.
  • Install man-in-position switches on mobile bridge conveyor systems so all MBC operators know everyone is in a safe position before initiating machine movement.
