The total operating costs of each mine largely depend on the method of mining. Therefore, the appropriate choice of the method of mining excavation is very important and great attention is paid to this issue. There are several procedures for the selection of the mining method, among which the most important and most commonly …

Introduction. Mining method selection is a process whereby the mining method attributes are matched to the orebody characteristics. The mining method whose attributes most closely match the orebody characteristics is the one with the highest potential for successful extraction and, by implication, should result in the best business case.

Different mining methods are designed to produce different types and magnitudes of displacements, in the near-field and far-field domains of an orebody. For example, the mining method illustrated schematically in Figure 12.2 is designed to restrict rock displacements in both the near field and the far field of the orebody to elastic orders
