The transition from surface mining to underground is a critical issue for metal mines. The commonly cited procedure cored by ultimatepitlimit (UPL) methodology is restricted to maximize the profit from both surface and underground mining, due to the absence of the integration of the profit from either of them. Under the target for such maximization, this study proposes a new optimization ...
