A Review of Models and Algorithms for Surface-Underground Mining Options and Transitions Optimization: Some Lessons Learnt and the Way Forward

It is important that the strategic mine plan makes optimum use of available resources and provides continuous quality ore to drive sustainable mining profitability. This requires development a well-integrated strategy options for surface and/or underground their interactions. Understanding current tools methodologies used in industry transitions planning are essential dealing with complex deep-seated deposits amenable both open pit mining. In this study, extensive literature review gap analysis matrix identify limitations opportunities further research surface-underground optimization comprehensive resource planning.
