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.

Fatality #13 & #14 for Metal/Nonmetal Mining 2010

On August 12, 2010, a 38 year-old maintenance technician with 3 years of experience and a 47 year-old operations miner with 21 years of experience died at an underground gold mine. They were working from the top of a conveyance in a 16-foot diameter ventilation shaft attempting to locate and free a blockage in a 24-inch-diameter aggregate delivery pipe. While the conveyance was near the 820 foot level, the entire pipe from the shaft collar to the 860 level broke away and fell to the bottom at the 1330 foot level. The pipe struck the conveyance as it fell, causing the hoist drum to break away from its support base. The victims were found at the bottom of the shaft.

Best Practices
  • Routinely examine pipe support structures for indications of excessive corrosion and cracked, missing, or damaged: clamps, brackets, support beams, and connections.
  • Conduct periodic visual and non-destructive examination on couplings and pipes for corrosion, abrasion thinning, cracking, and loose connections.
  • Inspect and test process monitoring systems to ensure safety controls are functioning properly.
  • Perform construction and maintenance in accordance with design drawings and specifications.
  • Minimize exposure to hazards by using equipment such as air cannons and vibrators to prevent or clear blockages.
  • Ensure that miners are in a safe position to avoid falling objects or materials.

On May 28, 2010, a 59-year-old supervisor with 20 years of experience was fatally injured at an underground gold mine. The victim and another miner entered a blast area when a misfire detonated without warning. The other miner was injured and hospitalized.

Best Practices

  • Follow the manufacturers’ guidelines for the storage and usage of explosives.
  • Keep explosives storage areas clean, dry and orderly.
  • Properly rotate explosive stock to use oldest stock first.
  • Never use damaged/deteriorated/outdated explosives, initiation devices, or blasting agents.
  • Wait a minimum of the required times before entering the blast area when either a misfire and/or burning explosives are a possibility.

On June 6, 2009, a 57-year old surface driller with 27 years of experience was fatally injured at a surface gold mine. The victim was drilling in a pit, exited the drill, and was walking in the drill area when he was struck by a flatbed truck as it backed up. The truck was in the area to collect drill cutting sample bags.

Best Practices
  • Before moving mobile equipment, look in the direction of travel, use all mirrors, cameras, and installed proximity detection devices to ensure no one is in the intended path.
  • Sound the horn to warn persons of movement and wait to give them time to get to a safe location.
  • Operate mobile equipment at reduced speeds in work areas.
  • Do not operate mobile equipment in reverse for extended distances when it is possible to travel forward.
  • Be aware of the location of mobile equipment in your work area before exiting your equipment.
  • Communicate with mobile equipment operators and ensure they acknowledge your presence.
  • Wear high visibility clothing when working around mobile equipment.
  • Train all miners to recognize work place hazards.
