• Selection of a feasible mining method requires the comparison of the characteristics of the deposit with those essential for different mining methods • In general, most selection techniques deal primarily with: 1. The physical and geologic characteristics of the deposit 2. The ground conditions of the hanging wall, footwall and ore zone

The presented procedure was assessed during underground mining method selection and determination of optimal transition depth from open-pit to underground for Gol-e-Gohar Area 3 iron ore deposit in Iran. It is concluded that the most suitable underground method for mining the rest of ore deposit below the open-pit is stope and pillar.
