Optimization of open pit to underground transition depth: An idea for reducing waste rock contamination while maximizing economic benefits
AS Khaboushan, M Osanloo, A Esfahanipour - Journal of Cleaner …, 2020 - Elsevier
As open pit (OP) mines grow downward, more waste rocks are produced. Thus, the waste
removal and management costs increase exponentially. On the other hand, waste rocks …
