Unit 3 Reading: Mining and Mining Impacts

In surface mining, approximately 2--3 tons of waste rock is removed for each ton of ore. Underground mining generally creates less waste rock than surface mining; the waste rock is either moved to the surface or used to fill in areas of the mine no longer in use. Piles of waste rock are usually deposited close to the mine.
