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

Liste de Caractéristique de GeoModeler

Import assays, attributes (categorical or continuous) and geological structures including faults; Desurvey drill holes with choices of 5 desurvey algorithms; Composite and color-code drill holes by lithology, attributes or assays; Create custom DDH attributes as input to subsequent block model interpolations; Create planned drill holes for drilling planning.

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.

Create distribution bar charts and curves for drill hole assays, composites and block models; Validate block models using Histogram Comparison Plot, Q-Q & P-P plots and Swath plots.

classify and export estimated blocks into measured, indicated and inferred categories for public reporting; Advanced custom report generation with ThreeDify’s formula-based Block Model Report Generator.

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.
