Fatality #11 for Metal/Nonmetal Mining 2012

renewcomerLeave a comment

On August 31, 2012, a 49-year old driller with 24 years of mining experience was killed at an underground gold mine. The victim was assigned to prepare the work area to set up a long-hole bench drill and was working near an open stope when he fell down the stope. He was inadvertently loaded out with the material and transported by a haul truck to the surface where he was later discovered.

Best Practices
 

  • Always use fall protection with a lanyard anchored securely when working where there is a danger of falling.
  • Examine workplaces for changing conditions when the strata, drill patterns, or other workplace conditions change.
  • Establish policies and procedures for safely clearing hung or stuck material and ensure that persons follow those safe policies and procedures.
  • Ensure that persons are task-trained and understand the hazards associated with the work being performed.
  • Ensure that areas are barricaded or have warning signs posted at all approaches where hazards exist that are not immediately obvious.
  • Consider using a “miner in distress” call feature available on many communication and tracking systems carried by miners. This feature is designed to improve emergency response if a miner working alone or out of sight of other miners requires immediate assistance.

On July 26, 2012, a 49-year old equipment operator with 18 weeks of mining experience was killed at a portable crushing operation. He was standing on the discharge end of a 150-foot stacker belt conveyor, greasing the head pulley, when a coworker started the conveyor. The victim fell off the conveyor approximately 50 feet to the ground below.

Best Practices
 

  • Provide and maintain a safe means of access to all working places.
  • Establish policies and procedures for conducting specific tasks on belt conveyors.
  • Ensure that persons are task trained and understand the hazards associated with the work being performed.
  • Deenergize and Lock-out/tag-out all power sources before working on belt conveyors.
  • Block belt conveyors against motion before working near a drive, head, tail, and take-up pulleys.
  • Maintain communications with all persons performing the task. Before starting belt conveyors, ensure that all persons are clear.
  • Sound an audible alarm prior to start up, if the entire length of the belt conveyor is not visible from the starting switch.
  • Clearly label all switches on equipment and provide training to persons who operate and work in the vicinity of equipment.

  • Operating speeds shall be consistent with conditions of roadways, tracks, grades, clearance, visibility, curves, and traffic.
  • Slow down or shift to a lower gear when necessary. Post areas where lower speeds are warranted.
  • Always wear a seat belt when operating self-propelled mobile equipment.
  • Do not attempt to exit or jump from moving mobile equipment.
  • Provide adequate site specific hazard training to all customer truck drivers.

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.

Fatality #2 for Metal/Nonmetal Mining 2012

renewcomerLeave a comment

On February 14, 2012, a 40 year-old mine owner with 8 years of experience was killed at a shale operation. The victim was operating an excavator with a rock breaker attachment. He was breaking and mining material from a near vertical wall when the face fell onto the cab of the excavator, crushing him.

Best Practices

  • Operate excavators with the cab and tracks perpendicular to, and away from, the highwall.
  • Bench or slope the material to maintain stability and to safely accommodate the type of equipment used. Do not undercut material on the face of a slope, bank, or highwall.
  • Examine highwalls, slopes, and banks from as many perspectives as possible (bottom, sides, and top/crest) while maintaining the safety of the examiner(s). Look for signs of cracking, bulging, sliding, toppling or other signs of instability. Record the type and location of hazardous conditions.
  • Use auxiliary lighting during non-daylight hours to conduct highwall examinations and to illuminate active work areas.
  • Perform supplemental examinations of highwalls, banks, benches, and sloping terrain in the working area.
  • Immediately remove all personnel exposed to hazardous ground conditions and promptly correct the unsafe conditions. When the conditions can not be corrected, barricade and post signs to prevent entry.
  • Remove loose or overhanging material from the face. Correct hazardous conditions by working from a safe location.
