On Saturday, July 14, 2012, a 25-year old water truck driver with 31 weeks of experience was killed at a surface mine. The victim was driving a water truck down a grade in an active work area of the mine when he lost control of the truck. The truck struck a berm on the right side of the roadway, traveled across the roadway, struck an embankment on the left side of the roadway and overturned, ending up facing opposite the original direction of travel. The victim was found ejected from the truck.

  • Train all employees thoroughly on proper work procedures, hazard recognition and avoidance, and proper use of roadway berms.
  • Conduct pre-operational checks to identify defects that may affect the safe operation of equipment before being placed into service.
  • Never operate a truck or other mobile equipment without using a seat belt.
  • Know the truck’s capabilities, operating ranges, load-limits, and maintain the brakes and other safety features properly.
  • Construct roadway berms to appropriate strengths and geometries. Ensure all grades and haulage roads are appropriate for the haulage equipment being used.
  • Maintain control of equipment at all times, making allowances for the prevailing conditions (low visibility, inclement weather, etc).
  • Observe all speed limits, traffic rules, and ensure that grades on haulage roads are appropriate for haulage equipment being used.
  • Always select the proper gear and downshift well in advance of descending the grade.
  • Maintain equipment braking and steering systems in good repair and adjustment. Never rely on engine brakes and transmission retarders as substitutes for keeping brakes properly maintained.
  • Monitor work habits routinely and examine work areas to ensure that safe work procedures are followed.
  • Do not attempt to exit or jump from a moving vehicle .

On Monday, June 25, 2012, at approximately 11:45 AM, a 33-year-old outby foreman with 7 years of experience was killed while installing additional rib/roof support in the No. 5 belt/track entry. The victim was wedging a timber against the mine roof to support the rib, when a section of the left hand rib rolled on top of him. The rock was approximately 14 feet long, 4 feet high, and 17 inches thick.

  • Conduct thorough pre-shift and on-shift examinations of the roof, face, and ribs. A thorough exam must be conducted before any work or travel is started in an area and thereafter as conditions warrant.
  • Support any loose roof or rib material adequately or scale loose material from a safe location before working or traveling in an area.
  • Danger-off areas that have hazardous roof or rib conditions until they are made safe.
  • Take additional safety precautions when mining heights increase because rib fall injury rates increase substantially as the mining height increases.
  • Use rib bolting to control unstable ribs. Rib bolts provide the best protection against rib falls and are most effective when installed on cycle and in a consistent pattern.
  • Be alert to changing geologic conditions which may affect roof/rib conditions.
  • Ensure that the Approved Roof Control Plan is followed and is suitable for the geologic conditions encountered.
  • Revise the Approved Roof Control Plan as needed when adverse conditions are encountered.

On May 24, 2012, a 43-year-old shaft worker with 39 weeks of mining experience died from injuries he received on May 15, 2012. The victim was helping pour concrete in a 30-foot diameter shaft that was under construction. The victim and his coworkers were using a hose to direct concrete into forms that lined the shaft wall. The hose was overloaded as concrete came out of the hopper too fast, which caused the hose to surge. This sudden movement of the hose knocked the victim and his coworkers off their feet, resulting in a fracture to the left leg of the victim. The victim was treated at a local hospital and released. On May 24, 2012, he passed away at his residence as a result of complications of this injury.

Best Practices

  • Provide a means to control water, air, concrete, etc., lines when they are pressurized to prevent surges and other unintended movement.
  • Train miners on procedures and safety precautions to take if the discharge line becomes plugged or overloaded.
  • Provide positive communication between the worker controlling the flow and the workers manually handling the concrete hose.
  • Safety chains or guarding should be used at concrete hose discharge location.
  • Anchor the discharge line to prevent it from movement in the event of a surge.

On May 23, 2012, a 36 year-old foreman with about 9½ years of experience was killed at a sand and gravel operation. He was operating an excavator on a dike separating two ponds. The ground beneath the excavator tracks failed and the excavator toppled into one of the ponds.

Best Practices

  • Examine work areas to identify all hazards and remediate before starting any work.
  • Evaluate the stability of the ground (slopes and berms) prior to operating equipment near any drop off or edge.
  • Always be attentive to changes in ground conditions and visibility when operating machinery.
  • Perform the work at a safe distance away from the edge of a pond or where the stability of the ground may be unknown.
  • If a potential hazard is present, use long reach equipment to limit exposure and maintain a safe distance away.
  • Consider areas that have experienced previous slope failures to be unstable and do not approach until the area is evaluated for stability.
  • Wear flotation devices where there is a danger of falling into water.
  • Be alert to changes in ground conditions such as cracking, bulging, sloughing, undercutting, and erosion.
