Determination of Mining Limits (ML) for each of Open-Pit (OP) and Underground (Ug) is one of the most significant part impacts the economic aspects. Optimization process for the mentioned objective in both of OP and Ug mining was done on the economic block model. In this paper, the applied Optimization Algorithms (OA)s for ML determination extensively were studied. Because of the major difference between the shape and form of mining limits in two main exploitation methods, implementation of the algorithms in searc...

Under similar conditions, surface mining is generally regarded to be more advantageous than underground mining. In the selection between surface and underground exploitation methods, there are a number of most significant factors must be briefly studied and determined. In this study, these factors were extensively studied and then considering effect of these factors on surface and underground mining, a comparison was done.
