capital cost in open pit optimization

Forecasting mining capital cost for open-pit mining ...

2019-8-23  Mining capital cost (MCC) is one of the essential criteria for assessing the feasibility of an open-pit mine (or underground mine). The MCC heavily influences the net present value (NPV) of the projects over the lifetime of the mine.

Mathematical Optimization Models and Methods for

2011-9-20  In this thesis, we study the open-pit design problem, the open-pit mining scheduling problem, and the open-pit design problem with geological and price uncertainty. These problems give rise to (mixed) discrete optimization models that in real-life settings are large scale and computationally challenging. The open-pit design problem is to find an optimal ultimate contour of the pit, given
