Green Mining - Massachusetts Institute of Technology
About 73% of extracted rock goes to waste. Meanwhile, underground mining wastes only 7% of the extracted rock but is more expensive (Hartmann and Mutmansky, 2002). In situ mining (see mining solution page) can be more environmentally friendly than underground mining and is cheaper than many mining methods (Ulmer-Scholle, 2008).
