c04On Monday, March 16, 2015, a 34-year-old section foreman with 10 years of mining experience was killed when a coal/rock rib approximately 90 inches long, 45 inches high, and 15 to 18 inches thick fell and pinned him against the side of a shuttle car.

Best Practices

  • Be aware of potential hazards at all times when working or traveling near ribs.
  • Avoid areas of close clearance between ribs and equipment.
  • Know and follow the approved roof control plan and provide additional support when cracks or other abnormalities are detected.  Remember, the approved roof control plan contains minimum requirements.
  • Install rib bolts on cycle and in a consistent pattern for the best protection against rib falls.
  • Train all miners 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 alert for changing conditions.  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.

c03On March 8, 2015, a 45-year old assistant longwall coordinator with twelve years of experience was killed while working a longwall section.  The victim was shoveling loose material between the longwall face and the pan line when a large piece of rock, 12 feet long by 5 feet wide by 1 foot thick, fell from the face and struck him.

Best Practices

  • Conduct thorough and more frequent examinations of the roof, face, and ribs, when abnormal conditions are present.  Watch for frequently changing conditions.
  • Scale hazardous roof, face, or rib conditions and adequately support the areas before any work or travel is permitted.  Ensure that a bar of suitable length and design is used when removing loose or unconsolidated material.
  • Install longwall shield extensions to cover a portion of the face and minimize unsupported areas.
  • Implement policies, programs, procedures, and controls to protect miners working in the face conveyor areas.
  • Reinstruct all miners in hazard recognition, adequate support methods, and safe work practices when abnormal conditions or circumstances are present on the longwall face.

Fatality #2 for Coal Mining 2015

renewcomerLeave a comment

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.

Fatality #1 for Coal Mining 2015

renewcomerLeave a comment

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.

renewcomerLeave a comment

m04On January 26, 2015, a 57-year old heavy equipment operator with 36 years of experience was seriously injured at a phosphate mine.  He was operating an excavator near a water filled ditch when the excavator tipped forward and went in the water, submerging the cab.  The victim was removed from the cab and transported to a hospital where he died later that day.

Best Practices

  • Task train all persons to recognize all potential hazardous conditions and safe job procedures to identify and eliminate all hazards before beginning work, specifically the limited visibility of large equipment.
  • Discuss safe work procedures before beginning work.  Identify and control all hazards associated with the work to be performed and the methods to properly protect miners.
  • Provide traffic patterns and roads that minimize the danger of machines traveling near bodies of water.
  • Conduct examinations of travelways to evaluate hazards.
  • Install barriers, markers, or other warning devices to aid equipment operators where travelways are not recognizable or hazards are not apparent.  Limit travel of mobile equipment and inform mobile equipment operators of hazards.
  • Do not travel into areas where ground conditions can’t be verified.  If necessary, use the bucket of the machine to probe the travel/work area to check the ground conditions.

m03On January 21, 2015, a 54-year old miner (ground support) with 4 years of experience was killed at an underground lead mine.  The victim was operating a mechanical scaler in an intersection when a roof fall (55 feet long x 20 feet wide x 6 feet thick) occurred, covering the machine.

Best Practices

  • Establish safe work procedures that ensure a safe work location for miners conducting scaling operations, and train all miners to recognize and understand these procedures.
  • Discuss safe work procedures before beginning work.  Identify and control all hazards associated with the work to be performed and the methods to properly protect miners.
  • Always examine and test areas for loose ground before starting to work, after blasting, and as ground conditions warrant.
  • Identify and scale loose material from a safe position which will not expose miners to falling material.
  • Test for loose material frequently during work activities.  Be alert to any change of ground conditions.
  • Install ground support in roof and ribs where conditions warrant.
  • Use equipment with a reach that reduces the possibility of the equipment being struck by falling material.
