# Why They Dug the World’s Biggest Hole Source: https://www.youtube.com/watch?v=x_SgL10cYgQ Recap page: https://rapidrecap.app/video/x_SgL10cYgQ Generated: 2026-09-30T16:03:22.467+00:00 --- ## The Gist The Bingham Canyon Mine in Utah was dug continuously for 119 years to extract copper. It is the largest man-made excavation in the world, measuring three-quarters of a mile deep and two and a half miles wide. ## Quick Overview The Bingham Canyon Mine in Utah is the largest man-made excavation on Earth, functioning for over a century to extract massive amounts of copper ore. Extracting the mineral requires drilling and blasting 100,000 tons of rock at a time, creating a massive terraced pit that is visible from space. Although the operation generates vast amounts of copper and economic value, it also produces severe environmental hazards like acid-leaking pyrite waste. **Key Points:** - The Bingham Canyon Mine in Utah is three-quarters of a mile deep and two and a half miles wide. - The 21 different mining operations in the region consolidated over time into one massive company and one giant hole. - Miners drill 55-foot holes and use explosives to blast roughly 100,000 tons of rock per day. - The pit is dug in concentric rings called benches, which are designed to maximize ore collection without causing structural collapse. - In 2013, a massive landslide caused 1.5 billion dollars in damage and destroyed three of the four operational rope shovels. - Pyrite, a mineral found in abundance at the site, reacts with air and water to produce sulfuric acid, creating severe environmental challenges. - Climatize operates as an SEC-registered platform allowing individuals to invest in clean energy projects. ![Screenshot at 00:35: An aerial view of the Bingham Canyon Mine in Utah, showcasing the sheer scale of the largest man-made excavation on Earth.](https://ss.rapidrecap.app/screens/x_SgL10cYgQ/00-00-35.jpg) **Context:** Humanity has spent centuries digging massive holes into the Earth for resource extraction. While most major mining operations eventually close or merge, the Bingham Canyon Mine in Utah stands out as the ultimate mega-excavation, operating continuously for over a century to supply global copper demand. ## Detailed Analysis The Bingham Canyon Mine in Utah stands as the largest man-made excavation on Earth, spanning three-quarters of a mile deep and two and a half miles wide. Originally home to 21 separate mining operations, the area consolidated into a single massive enterprise over decades of digging. Extracting copper from the site requires a meticulous process of drilling 55-foot holes, packing them with explosives, and blasting roughly 100,000 tons of rock at a time. The pit is dug in concentric rings called benches, meticulously engineered to maximize ore recovery while preventing catastrophic landslides. However, maintaining these steep angles carries severe risks, as evidenced by a massive 2013 landslide that caused 1.5 billion dollars in damage and destroyed three massive rope shovels. Beyond the logistical challenges, the mine generates severe environmental hazards. Pyrite makes up a large portion of the extracted rock, and when exposed to air and water, it produces sulfuric acid. This acid runoff, combined with other heavy metals, has placed Utah near the top of toxic chemical release lists. Despite the environmental toll and the immense cost of maintaining operations, the mine remains profitable because its advanced infrastructure and existing setup make it cheaper to operate than digging a new hole from scratch. ### History and Scale of the Bingham Canyon Mine The Bingham Canyon Mine is an engineering marvel that has dominated the landscape of Utah for more than a century. - The mine is three-quarters of a mile deep and two and a half miles wide, making it large enough to be seen clearly from space. - Over the course of 119 years, 21 different mining operations in the region consolidated into a single massive company running one unified pit. - The ore system in Utah is unusually concentrated, allowing a single massive hole to remain viable for over a century. ![Screenshot at 01:21: A geological diagram illustrating the concentrated ore systems that made the Bingham Canyon site uniquely viable for long-term excavation.](https://ss.rapidrecap.app/screens/x_SgL10cYgQ/00-01-21.jpg) ### Mining Operations and Blasting Mechanics Extracting copper from the massive pit requires a continuous cycle of drilling, blasting, and hauling. - Workers use massive drills to bore 55-foot holes straight into the floor of the pit in dense clusters. - Explosives are detonated to shatter roughly 100,000 tons of rock per blast, a process repeated two to four times a day. - Fleet rope shovels and massive dump trucks collect the rubble and transport it to processing facilities. ![Screenshot at 02:27: A rope shovel loads shattered rock and rubble into a massive dump truck following a daily blast.](https://ss.rapidrecap.app/screens/x_SgL10cYgQ/00-02-27.jpg) ### The Bench System and the 2013 Landslide Digging a hole this deep requires precise geometry to prevent the entire structure from collapsing. - The pit is excavated in concentric rings called benches, which are designed to maximize ore collection without violating the laws of physics. - Benches are built in 50-foot increments with slopes ranging between 50 and 80 degrees to balance hauling access and structural stability. - In 2013, overly steep angles triggered the largest man-made landslide in history, causing 1.5 billion dollars in damage and destroying three rope shovels. ![Screenshot at 03:32: An aerial view showing the devastation left behind by the 2013 landslide at the Bingham Canyon Mine.](https://ss.rapidrecap.app/screens/x_SgL10cYgQ/00-03-32.jpg) ### Environmental Consequences and Pyrite Runoff The vast scale of the excavation brings severe environmental complications that persist long after extraction. - Pyrite exists in quantities ten times greater than copper within the mine, and it produces sulfuric acid immediately upon exposure to air and water. - Hundreds of millions of tons of acidic waste sit in massive piles around the perimeter of the hole. - The accumulation of toxic chemical releases places Utah near the top of state rankings for industrial pollution sources. ![Screenshot at 05:16: A pool of acidic runoff water collecting near exposed pyrite rock formations within the mining area.](https://ss.rapidrecap.app/screens/x_SgL10cYgQ/00-05-16.jpg)
