c07On Tuesday, March 17, 2015, a 52-year-old contract truck driver was killed while driving a fuel truck on a mine haulage road.  The tandem axle truck was found on its top near the bottom of a long descending grade which included a sharp curve to the right.  The fuel truck was fully loaded with approximately 3,500 gallons of diesel fuel.  After interviews, investigators could not determine if the victim was wearing a seatbelt at the time of the accident.

Best Practices

  • Always wear your seatbelt while operating mobile equipment.
  • Incorporate engineering controls that require seat belts to be properly fastened before equipment can be put into motion.
  • Monitor employees regularly to ensure seat belts are worn.
  • Maintain full control of equipment at all times while it is in motion.  Take into account weather and road conditions (steep grades, inclement weather, low visibility, etc.).  Ensure work areas are properly illuminated at night.
  • Never exceed a vehicle’s design capabilities, operating ranges, load limits, and safety features.  Always select the proper gear and shift to this lower gear well in advance of descending grades.
  • Maintain equipment braking systems in good repair and adjustment.  Never rely on engine brakes and transmission retarders as substitutes for keeping brakes properly maintained.
  • Conduct thorough pre-operational examinations to identify and repair defects that may affect the safe operation of equipment before it is placed into service.
  • Post conspicuous signs along haulage roads to inform operators of speed limits, approaching grades and curves, and the use of an appropriate gear to maintain a safe speed.

c02.jpgOn February 20, 2015, a 29-year-old roof bolter helper with 3 years and 48 weeks of mining experience was killed when a piece of rock approximately 3 feet wide, 11½ feet long, and 3 to 16 inches thick fell and pinned him against the top of the drill canopy of a roof bolting machine.  The roof bolting machine was positioned to install the next row of permanent supports when the accident occurred.

Best Practices

  • Visually examine the roof, face, and ribs immediately before any other work is started in the area.
  • Be alert to changing conditions, especially after activities that could cause roof disturbance.
  • While under supported roof, perform sound and vibration tests where roof supports are to be installed.
  • Establish in the roof control plan a bolt installation pattern that effectively supports the roof strata.
  • Adequately support or scale down any loose roof or rib material from a safe location.
  • Ensure that ATRS systems on all roof bolting machines are maintained in good working condition.  Ensure the ATRS sets firmly against the mine roof, as specified by the manufacturer, before installing new roof supports.
  • As much as possible, stay under the roof bolting machine’s drill canopy when working in the area between the ATRS and the last row of permanent roof supports.
  • Take additional measures when hazards associated with draw rock are encountered, such as mining shorter cuts and decreasing roof bolt spacing.
  • When using roof screen, implement work procedures that incorporate positioning and securing the mesh from a safe location.
  • Know and follow the approved roof control plan.  Install and examine test holes regularly to check for changes in roof strata.
  • Add additional supports at any indication of adverse roof conditions.

c01.jpgOn Wednesday, January 28, 2015, a 43-year-old continuous mining machine operator with 10 years of mining experience was killed when he was pinned between the conveyor boom of a remote controlled continuous mining machine and a coal rib.  The victim was operating the continuous mining machine from a remote position in the entry and was preparing for the next mining cycle when the accident occurred.

Best Practices

  • Install and maintain proximity detection systems to protect personnel and eliminate accidents of this type. See the proximity detection information page on the MSHA website (Proximity Detection Single Source).
  • Avoid “RED ZONE” areas when operating or working near a continuous mining machine, especially when moving a remote controlled continuous mining machine.  Frequently review, retrain, and discuss avoiding “RED ZONE” areas (http://www.msha.gov/Alerts/20040407REDZONE2.pdf).
  • Ensure all miners, including the continuous mining machine operator, are outside the machine’s turning radius before starting or moving equipment.
  • Stay behind moving mobile equipment when traveling in the same entry, and maintain a safe distance from any moving equipment.
  • Use low tram speed when moving a continuous mining machine where the left and right traction drives are operated independently.  The continuous mining machine pivots quickly when the tracks tram over raised areas of the mine floor.
  • Never turn your back to a self-propelled machine or get into an area where it can swing into you.
  • Develop and follow effective policies and procedures for starting and tramming self-propelled equipment.  Train all miners regarding these policies and procedures.
  • Ensure that the continuous mining machine operator has full visibility of the area while tramming equipment.
  • Assign another miner to assist the continuous mining machine operator when the machine is being moved or repositioned.
