Guidelines for Structural and Geological Models in LOPs

Provider: SRK Consulting


The project aim is to providing direction on how to define a 3-D structural and geological model for use in open pit studies. The guidelines include the development of 3-D structural geology models, but is also inclusive of lithological and alteration geology models, that would be used as input for open pit geotechnical studies. It includes focus on the philosophy and mechanics of structural and geological model construction, characterization of faults, and evaluation of Reliability of all modelled geological features. The process of quantifying Reliability provides clarity on the confidence of different components of the model, strongly dependent on the complexity of the geological environment and supporting data. We therefore intend to provide guidance on new best practices for incorporating geological confidence into geotechnical slope design.
