method selection (Table 1). Since these mining methods were used to excavate some parts of this ore deposit, there are orientation parameters for these mining methods. For the optimal choice of mining method of excavation, we will use the multi-criteria decision-making method, i.e., the VIKOR method (Romero-Gelvez et al., 2015). …

Early hand loading gave way to the use of "automated" mining using slushers and, later still, Joy loaders. Hand tramming and mule haulage gave way to the use of mine locomotives. (See W. R. Crane, 1924, for a more complete description of iron mining methods in the early 1900s.) Automated iron ore mining using a scraper to load
