“…Methods for determining the parameters and indicators of the development system are constantly being improved, as evidenced by the data of papers [13][14][15][16][17][18]. The selected development subsystem in specific mining-geological and mining-technical conditions with the best parameters and environmentally friendly development of the deposit with the complete extraction of all reserves from the subsoil, useful components from mineral raw materials.…”

“…Whittle et al [18] used Whittle's opportunity cost approach [19] in order to embed a crown pillar between open pit and underground mining portions. They first used a graph theory approach and later modified its structure [20]. Chung et al [21] tried to use a Mixed Integer Programming (MIP) model for determining the optimum transition depth.…”

A B S T R A C TThere are some large scale orebodies that extend from surface to the extreme depths of the ground. Such orebodies should be extracted by a combination of surface and underground mining methods. Economically, it is highly important to know the limit of upper and lower mining activities. This concern leads the mine designers to the transition problem, which is one of the most complicated problems in mining industry. The transition problem is categorized as a strategic one and is formulated in the form of long-term production scheduling problems. This implies that the transition problem is highly affected by the uncertainties that are rooted in the quantity and quality of an explored orebody. The current study aims to evaluate the effects of geological uncertainty on transition depth. To this aim, an integer programming (IP) model was executed on different simulations of an orebody. The results indicate that the net present value (NPV) of the deterministic solution is greater than that of the basic alternative. However, the uncertainty-based solutions show that the NPV of the whole mining operation is lower than the basic and deterministic solutions mostly (more than 72% of the simulations). Nevertheless, there are some rare cases in which the NPV of the operation may increase ideally up to 2.5 % due to development of the pit bottom downward. Finally, because of a negligible difference between the average NPV of the simulations and that of basic alternative, it is expected that the primitive pit bottom would play the role of transition depth.

“…Specifically, the existing models do not incorporate essential developmental infrastructure such as primary and secondary mine accesses, ventilation requirement, and geotechnical support and reinforcement in the optimization framework. Results from these models Mining 2021, 1 113 often lead to localized optimal solutions or biased solutions that are usually impractical to implement in the mining environment [2,3,[11][12][13][14][15][16][17][18][19][20][21][22][23][24].…”

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