MINERAL RESOURCE MODELING OF VARIABLES WITH INEQUALITY CONSTRAINTS: A CASE STUDY OF AN IRON ORE DEPOSIT

Abulkhair, Sultan; Madani, Nasser (APCOM 2021, 2021-09)

In multivariate geostatistics, it is common to have different types of complexities between variables of interest. In this context, an inequality constraint is an example of complex bivariate relationships. Unfortunately, ...
IMPLICIT MODELLING OF GEOLOGICAL DOMAINS BY SUPPORT VECTOR MACHINE: TUNING THE PARAMETERS BASED ON CONSISTENCY OF THE INDICATOR VARIOGRAM

Ongarbayev, Ilyas; Madani, Nasser (APCOM 2021, 2021-09)

3D modelling of geological domains is an essential part of orebody modelling and resource classification. Conventionally, one applies a wireframing technique, which, in practice, is quite laborious. An automatic approach ...
