|}licting reports that say that Chuquicamata in Chile or that the Kennecott Copper Mine in Utah are the largest open-pit mines in the world. Here in Utah, we say that Kennecott is the largest open-pit mine in the world, but it seems that Chuquicamata also makes this claim. Can anybody confirm one way or the other which is true? bob rulz 10:47, August 7, 2005 (UTC)
- Nevermind, I've done some additional research and it seems that Kennecott Mine in Utah is indeed the largest open-put mine in the world. bob rulz 10:49, August 7, 2005 (UTC)

- Why not share your sources of some additional research with us. Vsmith 17:05, 7 August 2005 (UTC)

- Okay, I will. [1] [2] [3] [4] [5] and [6] (in the Did you Know? section) all say that the Bingham Canyon mine (Kennecott Copper Mine) is the largest open-pit mine in the world. Of what I found, only [7], [8], and the numerous Wikipedia mirrors said that the one in Chile was the largest. This thread on the discussion of the largest open-pit mine in the world gives conflicting views. bob rulz 07:21, August 14, 2005 (UTC)

- Kennecott Copper Mine is deeper, Chuquicamata enfolds a larger area

Surely largest should be measured as the highest volume extracted as compared to the origional ground surface? Other measurements like deepest and longest should not be counted as largest. Htaccess 05:29, 19 November 2005 (UTC)
Funny, as I got back from a trip to Hibbing, Minnesota where they said the Hull-Rust Mine is the largest open pit in the World Vohod 21:18, 19 August 2006 (UTC)
Yeah, I am from Hibbing and people up there do say that Hull-Rust-Mahoning Mine is the largest open pit mine in the world. After looking around a bit I see some publications say it is the largest open pit "Iron" mine in the world. Who knows for certain. Digdugsmug 01:56, 24 November 2006 (UTC)

[edit] Size of Australian gold mines
How do pits like Telfer and the Super Pit gold mine in Western Australia compare in size to those listed? Htaccess 05:29, 19 November 2005 (UTC)
- The Super Pit, when completely worked out, will be "3.8 kilometres long, 1.35km wide and go down to a depth of more than 500m" [9]. Does this help? Sliggy 00:41, 14 December 2005 (UTC)
The Superpit is a baby compared to the ones in Chile and to Bingham Canyon. However, people are forgetting that a lot of coal mines are worked by strip mining, which would if you ignore the fact they are backfilled, qualify them as the largest in the world. Odds are, it's one in Russia. Rolinator 15:19, 27 December 2005 (UTC)
[edit] Disambiguation (merge?)
I put the following disambiguation line at the top of the article:
- This is an article about a specific type of surface mining. For a more general treatment, see that article.
However, it seems to me that a better solution might be to just merge the two articles. However, the surface mining article does state that open-pit mining is a kind of surface mining. --Smithfarm 09:48, 30 March 2006 (UTC)
[edit] Open cast or open cut?
I've never heard of the term 'open cast'. I live in a region which contains a very large number of open cut coal mines, and I have worked in and around mines. I had never heard of open cast until I saw what I thought was a typo in the description of a photo in the Australia article.
Is open cast really a valid term, and if so, what is the etymology of 'cast'? This sounds remarkably as if someone has mis-heard 'open cut' and taken it from there. --Athol Mullen 23:06, 29 November 2006 (UTC)

- Opencast is the term used in British English. I believe it means the same thing as 'open cut' or 'open-pit'.62.31.12.18 01:03, 13 March 2007 (UTC)
[edit] Open Pit versus strip mine
The photo of the coal mine in Germany looks to me like a strip mine rather than an open pit mine. Perhaps it should be put instead in the Surface mining article under "area strip mining." Anyone know about this mine?Plazak 23:35, 25 March 2007 (UTC)
