Fatality #9 for Coal Mining 2016

On December 2, 2016, a technical representative for a shield manufacturer, with 13 years of experience, received fatal injuries while adding components to the hydraulic system of a longwall shield.  The victim was positioned inside the shield near the hinge point when the shield collapsed and crushed him.

Best Practices

  • Ensure that miners who install, remove, or maintain shields are trained on proper procedures.
  • Never remove hydraulic components without first determining if they are pressurized and/or supporting weight.  Ensure all stored energy is released or controlled before initiating repairs.
  • Never work on hydraulic components of both supporting cylinders of longwall shields simultaneously.  A shield can collapse if hydraulic components from both cylinders are removed, even if both cylinders have functioning pilot valves.
  • Never work on a component that supports a raised portion of the shield unless the shield is blocked against motion.
  • Be aware of potential pinch points when working on or near hydraulic components.  Examine work areas for hazards that may be created as a result of the work being performed.
  • Maintain good communication with co-workers.  Make sure those around you know your intentions.

Fatality #6 for Coal Mining 2016

c06On Monday, May 16, 2016, a 50-year-old motorman, with over 14 years of mining experience, was fatally injured when the diesel locomotive he was operating crashed through a closed airlock door.  The diesel locomotive was pulling six drop deck cars and had stopped to allow another motorman operating a trailing locomotive to separate the cars to provide the clearance needed to pass through the airlock.  As the other motorman was preparing to couple his locomotive to the cars, the train unexpectedly moved forward and continued away from him towards the slope bottom where it crashed through the closed outby airlock door.

Best Practices

  • Communicate your position and intended movements to other locomotive operators and other miners that may be in the area.
  • Always look in the direction of equipment movement and ensure travelways are clear.
  • Exercise caution in low clearance work areas and maintain adequate clearance for equipment.
  • Keep all body parts within the operator’s compartment while the equipment is in motion.
  • Maintain control of equipment so that it can be safely stopped.
  • Assure dead-man controls are fail-safe and maintain brakes and dynamic retarding controls.

Fatality #5 for Coal Mining 2016

c05On June 6, 2016, a 34-year-old contract laborer with 7 years of mining experience was fatally injured when a diesel-powered front-end loader fell on him.  Working together, another miner and the victim lowered the bucket and put downward hydraulic pressure on the bucket to raise the middle of the loader. Both miners then crawled under the loader.  The hydraulic pressure released, allowing the loader to lower, pinning both miners.  A mine examiner, who was nearby, lowered the bucket again to raise the loader off the miners.  One miner was freed and assisted in removing the unresponsive victim from under the loader.  Cardiopulmonary resuscitation (CPR) was performed, but the victim could not be revived.

Best Practices

  • Do not work under a suspended load.
  • Never depend on hydraulics to support a load.  Use the manufacturer’s recommendations to lift and block equipment against hazardous motion BEFORE starting any repairs.
  • DO NOT proceed with repairs until all safety concerns are adequately resolved, especially if potential hazards or prescribed procedures are unclear,.
  • Conduct examinations, from safe locations, to identify hydraulic leaks and assure repairs are conducted in accordance with the manufacturer’s recommendations.  Verify the release of, or fully control, all stored energy before initiating repairs.
  • Treat the suspended load as unblocked until blocks or jack stands are in place, fully supporting the weight, and equipment stability has been verified.
  • Establish and discuss safe work procedures before beginning work.  Identify and control all hazards associated with the work to be performed to ensure miners are protected.  Use the proper tools and equipment for the job.
  • Train all miners in the health and safety aspects and safe work procedures related to their assigned tasks.

c04On Friday, March 25, 2016, a 48-year-old continuous mining machine operator, with 30 years of mining experience, was fatally injured when an overhanging section of a rock rib fell and pinned him against the haulage equipment. The fallen rib was approximately 44 feet long, 4 feet wide, and 2 feet thick. The victim was remotely operating a continuous mining machine that was being used to excavate material during the construction of a coal transfer shaft. The area where the accident occurred had a depth of cover of approximately 1,950 feet and a height of approximately 17 feet.

Best Practices

  • Be aware of potential hazards at all times when working or traveling near mine ribs, especially when conditions exist that could cause roof or rib disturbance. Take additional safety precautions in these conditions and when mining heights increase.
  • Do not stand between ribs and remotely controlled face equipment.
  • Know and follow all provisions of the approved roof control plan.  Recognize that this plan has minimum requirements and additional measures must be taken as mining conditions warrant.
  • Train all miners to conduct thorough examinations of the roof, face, and ribs where miners will be working or traveling. Correct all hazardous conditions before allowing miners in such areas. Continuously watch for changing conditions and conduct more frequent examinations when abnormal conditions are present.
  • Pay particular attention to deteriorating roof and rib conditions when working in, or traveling through, older areas of the mine.  Provide additional training for specialized work, such as outby construction, emphasizing best practices for each specific task.
  • Perform a site-specific risk assessment for underground construction projects since unusual hazards may be encountered.  Identify and correct hazardous conditions related to falls of the roof, face, and ribs.
  • Install rib bolts on cycle and in a consistent pattern for the best protection against rib falls.
  • Provide additional support when fractures or other abnormalities are detected and use appropriate standing support beneath overhanging brows if they cannot be taken down or adequately bolted.
  • Adequately scale any loose rib material from a safe location with a bar of suitable length.
  • Historically, rib related accidents occur in areas where the mining height exceeds 7 feet and the cover is more than 700 feet. In such areas, make frequent examinations and take proactive measures to assure adequate, effective rib support is installed and maintained.

c02On January 16, 2016, a 31 year old continuous mining machine operator with 12 years of mining experience was fatally injured when a section of coal/rock rib measuring 4.5 feet long, 3 feet high, and 3 feet thick fell and pinned him to the mine floor. The victim was remotely operating the continuous miner in the number 2 entry of the advancing section when the accident occurred.

Best Practices

  • Train all miners and supervisors to conduct thorough examinations of the roof, face, and ribs where persons will be working and traveling. Correct all hazardous conditions before allowing persons to work or travel in such areas.
  •  Be aware of potential hazards at all times when working or traveling near ribs. Take additional safety precautions when mining heights increase to prevent development of rib hazards.
  • Avoid areas of close clearance between ribs and equipment.
  • Know and follow the approved roof control plan and provide additional support when roof or rib fractures, or other abnormalities are detected.  Remember, the approved roof control plan only contains minimum requirements.
  • Install rib bolts with adequate surface coverage hardware on cycle and in a consistent pattern for the best protection against rib falls. In addition to rib bolts and mesh, setting post on 4 foot centers along questionable rib lines will provide additional protection against rib rolls.
  • Be alert for changing conditions, especially after activities that could cause roof disturbance. Report abnormal roof or rib conditions to mine management.
  • Adequately support or scale any loose roof or rib material from a safe location.  Use a bar of suitable length and design when scaling.
  • Danger off hazardous areas until appropriate corrective measures can be taken.
