question: Chuquicamata is the second deepest open-pit mine after the Utah mine known as what among locals?
answer: Kennecott Copper Mine
context: Title: Chuquicamata
  Passage: Chuquicamata ( ), or "Chuqui" as it is more familiarly known, is by excavated volume the largest open pit copper mine in the world, located in the north of Chile, just outside Calama at 2850 m above sea level, 215 km northeast of Antofagasta and 1240 km north of the capital, Santiago.  Flotation and smelting facilities were installed in 1952, and expansion of the refining facilities in 1968 made 500,000 ton annual copper production possible in the late 1970s.  The mine is owned and operated by Codelco, a Chilean state enterprise, since the Chilean nationalization of copper in the late 1960s and early 1970s.  Its depth of 850 m makes it the second deepest open-pit mine in the world (after Bingham Canyon Mine in Utah, United States).
  Title: Bingham Canyon Mine
  Passage: The Bingham Canyon Mine, more commonly known as Kennecott Copper Mine among locals, is an open-pit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, in the Oquirrh Mountains.  The mine is the largest man-made excavation in the world and is considered to have produced more copper than any other mine in history – more than 19 million tonnes.  The mine is owned by Rio Tinto Group, a British-Australian multinational corporation.  The copper operations at Bingham Canyon Mine are managed through Kennecott Utah Copper Corporation which operates the mine, a concentrator plant, a smelter, and a refinery.  The mine has been in production since 1906, and has resulted in the creation of a pit over 0.6 mi deep, 2.5 mi wide, and covering 1,900 acre .  It was designated a National Historic Landmark in 1966 under the name Bingham Canyon Open Pit Copper Mine.  The mine experienced a massive landslide in April 2013 and a smaller slide in September 2013.
  Title: Rouchleau Mine
  Passage: The Rouchleau Mine is an abandoned open-pit mine within the Mesabi Iron Range at Virginia, Minnesota, United States.  The mine, located on the east side of the city, is roughly 3 mi long and .5 mi wide; its deepest point is 450 ft below its surface, making it one of the deepest mines in the range.  Named for Louis Rouchleau, who explored the area for its mining potential, the mine was initially created as a shaft mine.  It was converted to a pit mine by the 1930s due to improvements in open-pit mining technology and increasingly unstable terrain which made shaft mining unsafe.
  Title: Tellnes mine
  Passage: The Tellnes mine is one of the largest titanium mines in Europe.  The mine is located about 4 km northeast of the Jøssingfjorden in Sokndal municipality in Rogaland county, Norway.  The mine has reserves amounting more than 300,000,000 t of ore grading 18% titanium.  The deposit of titanium was discovered in 1954 and production at the mine began in October 1960.  Each year there is about 2,000,000 t of ore and 1,600,000 t of rock waste removed from the open-pit mine.  This resulted in about 580,000 t of ilmenite concentrate from the mine in 1999.
  Title: Victor Diamond Mine
  Passage: The Victor Diamond Mine is the first Canadian diamond mine located in Ontario, and De Beers' second diamond mine in Canada (after the Snap Lake Diamond Mine).  It is located in the Northern Ontario Ring of Fire, in the James Bay Lowlands 90 km west of Attawapiskat in the remote northern part of the province.  In June 2005, the Attawapiskat First Nation voted in favour (85.5%) of ratifying the Impact Benefit Agreement (IBA).  Construction of the mine began in February 2006 which created 3200 positions; mining and operations will create around 400 permanent positions.  The Victor Mine is an open-pit mine, with a processing plant, workshops, and an airstrip located on site.  By 2013-2014 royalties collected from De Beers Victor Diamond Mine amounted to $226.  At that time De Beers was continuing to pay off its "$1 billion investment to build the mine and from now until it closes, the company expects to pay tens of millions of dollars in royalties."
  Title: Raspadskaya coal mine
  Passage: The Raspadskaya Coal Mine is a coal mine located in Mezhdurechensk, Kemerovo Oblast, Russia.  It is the largest coal and the largest underground mine in Russia.  The mine was opened in 1973 and its construction was completed in 1977.  In addition to the main underground mine, the mining complex also includes MUK-96 underground mine, Raspadskaya Koksovaya underground mine, and Razrez Raspadsky open-pit mine, as also the Raspadskaya preparation plant.
  Title: Husab Mine
  Passage: The Husab Mine, also known as the Husab Uranium Project, is a uranium mine under development near the town of Swakopmund in the Erongo region of western-central Namibia.  The mine is located approximately 60 km from Walvis Bay.  The Husab Mine is expected to be the second largest uranium mine in the world after the McArthur River uranium mine in northern Saskatchewan, Canada and the largest open-pit mine on the African continent.  The Husab Mine is to start production in early December 2015 after completion of the sulfuric acid leaching plant.
  Title: Teghut Mine
  Passage: Teghut Mine is a major copper and molybdenum open-pit mine in Armenia's northern province of Lori in the village of Teghut with deposits valued at $15.5 billion USD (in 2010).  In December 2014, Vallex Group launched production operations at the mine, which is a $380 million USD project.  The mine will be comparable in size to the Kajaran Mine in southern Armenia.
  Title: Hambach surface mine
  Passage: The Tagebau Hambach is a large open-pit mine (German: "Tagebau" ) in Niederzier and Elsdorf, North-Rhine Westphalia, Germany.  It is operated by RWE and used for mining lignite.  Begun in 1978, the mine's operation area currently (as of 2011) has a size of 39 km², with the total area designated for mining having a size of 85 km².  It is the deepest open pit mine with respect to sea level: the bottom of the pit is 299 m below sea level, the deepest man-made point on the Earth's surface.
  Title: Las Bambas copper mine
  Passage: Las Bambas copper mine is a large project located in Apurímac, Peru.  It is an open-pit mine located at altitude of about 4000 meters above sea level.  It is a polymetallic mine which significant mineral resources and ore reserves of copper with an estimated mine life of at least 20 years.  Production at the mine is scheduled to start in 2015 following an 80% confirmation completion of the project on 31 Dec 2014.  The first production of concentrate out of the mine is expected to be in the first quarter of 2016.
