Fatality #8 for Coal Mining 2011

renewcomerLeave a comment

On Monday, June 27, 2011, a 33 year old miner was killed when a portion of coal and rock fell from the upper portion of a pillar rib. The material that fell was approximately 8 feet long, by 32 inches thick, by 3 feet high.

Best Practices

  • Conduct a thorough visual examination of the roof, face, and ribs immediately before any work or travel is started in an area and thereafter as conditions warrant.
  • Perform careful examinations of pillar corners, particularly where the angles are formed between entries and crosscuts are less than 90 degrees.
  • Support any loose rib or roof material adequately or scale before beginning work.
  • Take additional safety precautions when mining heights increase to prevent development of rib hazards.
  • In areas prone to deterioration, install rib support when the area is mined initially.
  • Be alert to changing geologic conditions which may affect roof/rib conditions.

Fatality #7 for Coal Mining 2011

renewcomerLeave a comment

On Thursday, June 9, 2011, a 53 year-old contract steelworker, with over 16 years of coal mine experience, was killed when he fell approximately 8 feet from a steel beam. He hit a lower cross beam before he landed on a conveyor belt cover located about 32 inches below the cross beam. The victim had been engaged in cutting operations just prior to the fall, and was repositioning when he removed his lanyard tie-off safety device from the location where it was secured.
Best Practices

  • Wear and use fall protection, maintaining 100 per cent tie off, when fall hazards exist.
    See TieOff.asp
  • Ensure workers are trained and understand the proper use of restraint devices.
  • Provide self retracting lanyard mechanisms when possible.
  • Ensure secure footing in all work areas.
  • Examine tools and personal protective equipment routinely and replace when defects or wear is evident.
  • Conduct a risk assessment of the work area prior to beginning any task and identify all possible hazards. Use the SLAM; Stop, Look, Analyze, and Manage approach for work place safety.

Humphreys Enterprises Inc. – No 5 Strip
Based on MSHA’s investigation and the finding of the death certificate, MSHA concluded that the miner died from natural causes and that the fatality should be de-listed and not charged to the mining industry. The death certificate indicated that the death was natural and was due to a cardiac arrhythmia due to a myocardial infarction which in turn was due to coronary artery atherosclerosis.”

Fatality #6 for Metal/Nonmetal Mining 2011

On June 4, 2011, a 39 year-old mill operator with 1 year and 14 weeks of experience was killed at a surface gold operation. The victim was sweeping in a crusher building when he fell through an opening approximately 60 feet to the floor below. The cover for the opening was not secured in place.

Best Practices

  • Establish and discuss safe work procedures. Identify and control all hazards. Train all persons to recognize and understand safe job procedures before beginning work.
  • Always use fall protection when working where a fall hazard exists.
  • Protect openings near travelways through which persons may fall by installing railings, barriers, or covers.
  • Keep temporary access opening covers secured in place at all times when the opening is not being used.
  • Ensure that areas are barricaded or have warning signs posted at all approaches if hazards exist that are not immediately obvious.

On Saturday, May 14, 2011, a 37-year old mechanic with 14 years of mining experience and 1½ years of experience as a mechanic, was killed while removing a counter weight fuel tank assembly from a front-end loader. He was positioned beneath the front-end loader when he removed 14 of the 16 mounting bolts that secure the counter weight. When the victim attempted to remove the next to last bolt, the remaining two bolts failed allowing the 11,685 pound counterweight to fall on him. The counter weight had not been blocked to prevent it from falling.

Best Practices
  • Install blocking materials before removing mounting bolts from machinery components which can fall during disassembly.
  • Follow known safe maintenance procedures.
  • Follow the equipment manufacturers recommended maintenance procedures when performing repairs to machinery.
  • Train new mechanics in the health and safety aspects and safe work procedures related to their assigned tasks.

On April 25, 2011, a 31 year- old drill operator with 6 weeks of experience was killed at an underground crushed stone operation. He was walking in a crosscut when a slab of roof, approximately 5 feet wide by 6 feet long by 10 inches thick, struck him.

Best Practices

  • Train persons to identify work place hazards and take action to correct them.
  • Design, install, and maintain a support system to control the ground in places where persons work or travel.
  • Examine and test ground conditions in areas where work is to be performed prior to work commencing and as ground conditions warrant during the shift.
  • When ground conditions create a hazard to persons, install additional ground support before other work is permitted in the affected area.
  • Be alert to any change of ground conditions.

On Friday, March 25, 2011, a 54-year old continuous mining machine operator with 35 years of experience was killed when he was caught between the coal rib and the conveyor boom of the remote controlled continuous mining machine he was operating.

Best Practices
  • AVOID “RED ZONES”!!! Prior to tramming the continuous mining machine to a new place, ensure the machine operator is positioned outside the turning radius of the machine. MSHA Red Zone webcast (pdf)
  • Prior to tramming the continuous mining machine to a new place, ensure the tip of the conveyor boom is positioned on the side of the mining machine opposite to the side where the machine operator is located.
  • Install MSHA approved Proximity Detection Systems on continuous mining machines. Proximity Detection Single Source
  • Assign another miner to assist the continuous mining machine operator. Train all persons in the programs, policies, and procedures for operating or working near remote controlled continuous mining machines. Additional information on preventing these types of accidents can be found at: MSHA’s Safety Targets Program Hit By Underground Equipment.
