A geotechnical model is the fundamental basis for the design of open pit and quarry excavations. A fully understood and representative geotechnical model will provide information on the engineering characteristics of the rock mass, defining how it is going to behave during and after excavation Read more... about Adding value using representative geotechnical models for mine design

Purpose of Risk Based Design

  • Cater for the inherent variability in rock mass conditions
  • To address uncertainty
  • To apply engineering judgement
  • To enable decisions to made based on the level of risk to the operation
  • Risk =

Dilution increases the operating costs in the mill by increasing the tonnage of material to be milled. By better understanding the root causes of the dilution, quanitiying it, and planning accordingly, it can be reduced.
