Historical Context
Bingham Canyon Mine, also known as the Kennecott Copper Mine, is one of the largest open-pit copper mines in the world, located near Salt Lake City, Utah. Over its long operational history beginning in the early 1900s, the mine has been a site of numerous events, labor disputes, and safety challenges shaping mining industry practices.
Labor Conflicts and Casualties
Bingham Canyon Mine’s history combines industrial achievements with episodes of human conflict and geological hazard. Labor disputes in the early 20th century led to casualties and highlighted the harsh realities of mining life. More recently, the massive 2013 Manefay landslides demonstrated how modern geotechnical monitoring and rapid response effectively prevented loss of life despite immense physical destruction. The mine continues to serve as a case study in the evolution of mining safety, worker rights, and environmental challenges.

Labor Conflicts and Casualties
- In 1912, a significant strike unfolded involving thousands of immigrant mine workers protesting poor wages and working conditions. The strike escalated into violent confrontations involving miners, strikebreakers, law enforcement, and military units.
- Clashes during the strike resulted in injuries and at least one confirmed death, with reported use of firearms and armed guards on all sides.
- The strike dramatically highlighted tensions around labor rights, immigration, and corporate practices during the early industrial mining era.
- On April 10, 2013, the mine experienced two massive landslides known as the Manefay slides, which together displaced approximately 165 million tons of rock material.
- Triggered by geological instability in the northeastern pit wall, these rock avalanches traveled at speeds over 70 mph, reshaped the mine, and buried infrastructure and surface equipment.
- Remarkably, extensive geotechnical monitoring and timely evacuations prevented injuries or deaths during the event.
- Damage included the destruction of 3 of 13 large hydraulic shovels and 14 haul trucks, with equipment costs in the tens of millions of dollars.
- The landslides rank among the largest non-volcanic landslides in recorded North American history.
- The Bingham Canyon Mine employs sophisticated geotechnical surveillance including ground movement sensors, seismographs, and infrasound monitoring that provided early warnings before the 2013 slides.
- Evacuations and safety protocols activated well in advance exemplify the importance of modern mine monitoring systems to protect life despite large-scale natural hazards.
- Historical fatalities and injuries during labor disputes contrast sharply with modern safety protocols that emphasize prevention and preparedness.
- Strikebreakers: Workers hired to replace striking employees, frequently a source of labor conflict.
- Rock Avalanche: A rapid, fluid-like movement of fragmented rock down a slope, often unstoppable by human intervention.
- Geotechnical Monitoring: The use of instruments and techniques to detect ground movement and stability to predict failures.
- Manefay Series: Geological formations within the Bingham Canyon area associated with landslide activity.
