Selection of mining method - QueensMineDesignWiki
Selection of mining method. Context: The selection of a mining method for a given orebody can be a challenging assignment and may need to address personal bias for or against a particular method.The selection of the mining method may also need to occur prior to the completion of desired geotechnical or ore value determinations.

OCTOBER TOPIC 11 MINING METHOD SELECTION
an important driver in mining method selection. Temporary and permanent openings must be developed either in the host rock, in order to access the ore, or with the host rock as roof (back or hanging wall) or floor (footwall) for the ore openings (entries or crosscuts). To execute an appropriate design, the material properties must be understood.

The AHP, developed by, Saaty (1980) is used in this research for the selection of the optimal mining method. The process is broken into five levels: (1) goals, (2) stra- tegic issues, (3) criteria, (4) rating scale, and (5) alterna- tives (Fig. 3). All five levels are defined and arranged into pairwise comparison matrices.
