3D geotechnical models using ordinary kriging in open pit mines
Award-winning paper in the Geotechnics and Engineering Geology category of the 21st Peruvian Geology Congress (Lima, October 2023).
Author: Eng. José Luis Ramírez Castañeda, General Manager of GEORAM.
Presented at: 21st Peruvian Geology Congress, Lima, October 2023 (published in Minería magazine in July 2024). Award-winning paper in Geotechnics and Engineering Geology.
What it is about
The paper presents a methodology for developing three-dimensional geotechnical models of open pit mines using ordinary kriging, a geostatistical technique that estimates rock mass properties between points sampled by drill holes and mapping.
Why it matters
These models provide a continuous characterization of the pit, define geotechnical domains and support slope design at bench, inter-ramp and overall scale.
