On Friday, November 30, 2012, a 58-year old bulldozer operator with 37 years of experience was killed when an upstream slope failure occurred at a coal slurry impoundment. The victim was grading the upstream slope at the time of the accident. The bulldozer was carried into the pool area during the slide and sank with the victim on board.

Best Practices
  • Provide hazard training to all personnel working on or near an impoundment for recognition of hazards associated with the impoundment and pushout work, such as surface cracks or bubbling in water/slurry.
  • Review safety precautions for upstream construction with equipment operators, along with material handling safety policies and designated storage areas for safety equipment.
  • Provide oversight by knowledgeable personnel at the work site. Assure that a person is present who is familiar with the mechanics of upstream construction and can recognize and have unsafe work practices and conditions corrected immediately.
  • Remove all personnel to a safe location when unsafe impoundment conditions are present.
  • Prior to initiating push-outs, expose the slurry delta by pumping excess surface water down to the maximum extent possible, and for as long as possible.
  • Use two-way radios or similar devices on all equipment during impoundment related construction, so that potential hazards can be communicated quickly with equipment operators and personnel.
  • Maintain a work skiff with oars and life jackets near the pushout area.

On Friday, November 30, 2012, a 27-year old electrician was killed when he was caught between a battery-powered maintenance scoop and the cutting head of a continuous mining machine. The accident occurred on a working section while the electrician was performing maintenance work on the cutting head of the continuous mining machine, which was parked in an entry.

Best Practices
  • Be aware of your location relative to mobile equipment movement and never position yourself between equipment in motion and a stationary object.
  • Mark the area where equipment is parked for maintenance with conspicuous reflective material, flashing lights, or other warning signs on both sides of the entry or crosscut to warn mobile equipment operators of a parked machine or the presence of other miners.
  • Train miners to establish and use effective communications working around equipment. Ensure that mobile equipment operators are aware of your location at all times.
  • Use approved translucent or transparent ventilation curtains for better visibility. Never put extraneous material or supplies on mobile equipment where it can obstruct the visibility of the machine operator.
  • When operating equipment, sound audible warnings while traveling around turns or blind spots, through ventilation curtains, and at any time the operator’s visibility is limited or obstructed.
  • Install proximity detection systems on all mobile face equipment.

On Saturday, November 17, 2012, a 30-year-old continuous mining machine operator was killed when he was pinned between the head of the remote controlled continuous mining machine and the coal rib. The victim had 3 years of mining experience, with 20 weeks of experience as a continuous mining machine operator. The victim had mined the left side of an entry and was repositioning the continuous mining machine to mine the right side when the accident occurred.

Best Practices

  • Install and maintain proximity detection systems. See the proximity detection single source page on the MSHA website.
  • Develop programs, policies, and procedures for starting and tramming remote controlled continuous mining machines.
  • Frequently review, retrain, and discuss avoiding the “RED ZONE” areas when operating or working near a remote controlled continuous mining machine.
  • Train all production crews and management in the programs, policies, and procedures and ensure that they are followed.
  • Ensure that mining machine operators are in a safe location while tramming the continuous mining machine from place to place or repositioning in the entry during cutting and loading.
  • Ensure everyone is outside the machine turning radius before starting or moving the equipment.
  • When moving continuous mining machines where the left and right traction drives are operated independently, low tram speed should be used.
  • Assign another miner to assist the continuous mining machine operator when it is being moved or repositioned. Train all persons in the programs, policies, and procedures for operating or working near remote controlled continuous mining machines.
