Geological mapping of waste rock dumps

Mine Earth has developed an innovative approach to assessing the erosion stability characteristics of waste rock landforms. Our approach involves geological mapping across the entire landform to identify stability zones. Representative sampling of key stability zones and supporting testwork can then be undertaken (as required) to verify geological observations. More effective final landform designs can be developed using erosion stability maps. The advantages of our approach include:
  • Geological skills are used to interpret deposit geology and the geological factors that control rock stability (lithology, mineralogy, structure, alteration and weathering).
  • A landform scale approach to stability assessment, rather than single point assessment and interpretation of sample results.
  • Co-disposed rock types and their relative abundance are considered, rather than an assessment of individual rock types in isolation.
  • Ability to predict the relative erosion / decomposition rates for various rock types and stability zones.
  • Rapid, efficient and cost effective approach.
  • Common laboratory methods of assessing the stability characteristics of waste rock are typically ineffective in determining as-dumped stability characteristics.
