Numerical Modeling of Geological Domains in K-MINE

Numerical modeling in K-MINE’s Geology module utilizes mathematical models to describe geological domains. With a set of interpolation functions, it calculates unknown values based on data from existing borehole samples. Exploration grids often vary irregularly in both area and depth; by using trend parameters and interpolants, K-MINE defines geological boundaries precisely.

Available models include Linear, Spherical, and Combined. In our example, modeling calcium oxide (CaO) content in a limestone deposit, we select the Spherical model with a linear drift, calculate the variogram, and set parameters to create wireframe surfaces.

Three methods of solid creation are provided: by value ranges, or thresholds greater or less than a specified limit. Selecting “Ranges,” we specify saving options and name our resulting layer—“Numerical Model”—while choosing display settings like color and fill.

Wireframe surfaces and solids are generated and clearly organized into sublayers. By adjusting parameters, completely different models can be obtained. Numerical modeling is effective for various deposit types, from polymetallic porphyry to thick ilmenite placers, though it is not recommended for stratiform deposits (kaolins, clays, or coal).

K-MINE’s visualization tools allow users to analyze geological domains effectively, compare borehole data with model sections, optimize results, and update surfaces as new data becomes available.
