GeoModeler

Modélisation géologique et estimation des ressources

GeoMine GeoModeler (GeoModeler), est un outil de modélisation géologique et d’estimation de ressources, pour gisements larges, complexes et à haute performance. Il offre une modélisation de blocs 3D, ainsi qu´une modélisation quadrillée 2D Grided Seam Modelling (GSM) de filon, une analyse géostatistique et une visualisation interactive 3D. Sa méthode d´interpolation de pointe sur surface, basée sur l’Anisotropie Dynamique (Dynamic Anisotropy(DA), assiste les géologues dans l’augmentation de la précision et dans la réduction des incertitudes liées à l’estimation des ressources. De même, il comporte un module de modélisation implicite basé sur un RBF facile d’utilisation, ainsi qu’un module pour classification de ressources et reportages pour des rapports destinés au public.

Principaux Avantages de GeoModeler

  • Précis : Technologie d’interpolation sur surface basée sur l’Anisotropie Dynamique, évite le piège général du nivellement exagéré dans l´estimation des ressources.
  • Puissant : Modèle de vastes et complexes gisements soit grâce à l´usage de modèles de blocs à haute résolution avec sous-blocage optimal ou modèle grillée de filon.
  • Flexible : Inclus tous les outils courants pour la manipulation de surface, de solide et de modèle de bloc dans le module de base (Foundation), ainsi qu´un outil d´accommodement du modèle de bloc.

model vein or seam type deposits with non-axis aligned Mine North and non-axis aligned block models; model large deposits with Octree universe; model dissiminated multi-orebody deposits with multiple block models in a single GeoModeler session; Create block model masks for open-pit deposits; Create and assign user-defined attributes to block models with a visual formula/scripting editor. manually assign rock code to parts of a block model using a solid mesh; includes integrated Block Model Reconciliation.

Create Gridded Seam Models (GSMs) from drill holes; Resource estimation for GSMs; Perform Magin Ranking on GSMs; Converting GSMs to Block Models for Lerchs & Grassman pit optimization for deeply inclined multi-seam GSMs.

sub-module: Automatically create lithology wireframes; Create real-time grade shells to quickly evaluate what-if scenarios.

sub-module: Model anisotropy with 3D per-mesh variograms and non-axis aligned ellipsoidal search radii.

Create normal faults, reverse faults, strike-slip faults or  combinations of the above fault types.

Apply faults to orebody wireframes and use them as constraints in pit or stope optimization.

Interpolate block model grades with high performance inverse distance power, anisotropic RBF (radial basis functions), nearest neighbour and multi-threaded Kriging methods (simple, ordinary, ordinary LVM) with or without geological domains. Includes an option to use powerful surface based dynamic anisotropy search strategy for more accurate resource estimates.

Imports drill holes in CSV or Microsoft Acess database format (*.mdb)

Create Dynamic Anisotropy (DA) surfaces either manually or automatically from a wireframe.

Create gridded topographical or geological surfaces from drill hole collars, categorical attributes, block models and/or an imported 2.5D mesh.
