What is the difference between an opencast mine and an open pit mine?

Question

Is there a difference? My tutor said there was but I can't find anything on the internet. Can you help?

Answer 1

An open cast is when it's a huge open area (with no roof, so you can look in and it lets the sun in), big enough to drive trucks around in. Like if the Grand Canyon was a mine. (Look up Kimberley's big hole for an idea)
Open pit, is when it's actually smaller tunnels, and eventhough trucks or rail carts can sometimes go in there, it's always underground (Look up Johannesburg gold mine shafts, also one of the deepest in the world)
Hope this helps.
