Real-time mining face grade determination using hyperspectral imaging techniques
Total Grant Value
Current practice of determining mining face ore grade prevents the creation of precise ore grade maps for use in mine planning and scheduling
This limits capacity for controlling mining processes, resulting in lower mine efficiency and productivity, and negatively impacting sustainability.
Hyperspectral imaging-based mapping is viable as a means for ore grade classification at the mine face.
This finding establishes the commercialisation potential of terrestrial hyperspectral imaging for real-time ore grade classification at the point of excavation.
Benefit to WA
Real-time ore grade classification at the mine face will bring substantial benefit to the large-scale efficient operations dominating Western Australia’s mining industry, including:
- enhanced mine scheduling;
- improved resource recovery and minimised processing waste; and
- supporting autonomous mining systems and machinery.
