A comprehensive three dimensional geotechnical model is fundamental to any pit slope design. This paper details a methodology for the collection, processing and spatial interrogation of geotechnical data that enables a robust three dimensional Mining Rock Mass Model (MRMM) to be constructed. The modelling techniques used to create the MRMM have been refined through their use on over forty mining projects that range from greenfields studies to mature producing mines. Case studies that illustrate the use of the MRMM and its versatility for the appreciation of geotechnical data as well as timely integration into the mine planning process are presented for a variety of open pit applications.
