Both Measurement While Drilling (MWD) and image analysis systems are useful tools that today are in use in mining industry. The data interpretation for both systems has been proposed by different studies, but often requiring site specific calibration. Sometimes the interpretation methods used by different researchers are in contrast. This may be caused by variation [...]
Development of design guidelines for underground platinum mine regional support pillars
Assessment of pillar stability is one of the most crucial steps in mine design (Sjöberg, 1992). South African platinum mines has reached a point where layouts made for shallow operations are insufficient due to increased depth, creating a necessity for new design layouts for medium depth mines (>1000 m). In this thesis, a design criterion [...]
