GEOVIA Surpac · 3D geology and mine planning

The block model every other decision on the mine is built on.

GEOVIA Surpac is the most widely used 3D geology and mine planning software in the world, and the one most Indonesian geologists learned first. ACALA licenses it, implements it, and trains on it, for open pit and underground operations from exploration to reconciliation.

Why Surpac

Three teams, one dataset, no re-typing between them.

Geologists, engineers and production teams work on the same drillhole database, the same block model and the same designs. What the geologist interprets is what the engineer designs against and what the surveyor reconciles.

Quantify a deposit with limited information

Geologists evaluate the physical characteristics of a deposit early, then tighten the model as drilling progresses, without starting over.

Design within the project’s constraints

Engineers visualise mine designs and plans that maximise ore recovery while respecting geotechnical, regulatory and equipment limits.

Extract with the numbers in hand

Production teams integrate survey, grade control and design data to decide the best way to extract reserves, and to prove it in reconciliation.

Roles in the Surpac portfolio

Eight roles, grouped the way the work flows.

Surpac is licensed by role. Each role is a set of tools for one job, and all of them read the same project.

1Geology

Block Modeler, Sectional Geology Modeler, Structural Geology Analyst

From drillholes to a resource model that reports to international standards.

Block Modeler

  • Spatial variability analysis and regularised volumetric block models.
  • Volume and quality of material within any extent; bench-based grade control for open cut.
  • Geostatistical analysis, mineral resource evaluation, reports to international standards.

Structural Geology Analyst

  • Orientations extracted from drillholes, points and block models.
  • Planes from point clouds or textured meshes, analysed on a stereographic projection.
  • Structural trend analysis on large and complex datasets.

Sectional Geology Modeler

  • Input, constrain, view and interpret drillhole, surface sample and survey data.
  • Compositing, sectional modelling, meshing and gridding of surface and subsurface geology.
  • Geological, structural and domain models; face mapping from point clouds and photogrammetric meshes.
  • Volumes and modelled quality of material within the area under investigation.
2Collaboration and survey

Mine Contributor, Surveyor

Everyone on site sees the same data, and the as-built geometry is updated every day.

Mine Contributor

  • Input, access and output geological and engineering data; view exploration data and mine information.
  • Complex surfaces and solids; a full CAD toolset for points and lines.
  • Massive point clouds imported, cleaned, meshed and reported on.
  • Workflow automation with scripting, record and playback; English, Chinese, Russian, Spanish and French.

Surveyor

  • Survey data from CMS, GPS and traditional instruments processed into as-built mine geometry.
  • Total material handled, rehandled or filled; set-out of locations and boundaries.
  • Compliance with survey regulation; control stations, infrastructure, as-built versus design maps.
  • Monthly volumes mined, filled and broken, for reconciliation.
3Design

Mine Designer, Drill and Blast Designer

Strategic plans become practical designs and blast patterns that crews can execute.

Mine Designer

  • Benches, berms and ramps for surface mining; stopes, tunnels, ramps and shafts underground.
  • Waste dumps, tailings dams and haul roads; geotechnical constraints such as slope stability.
  • Reserve reports of grade, tonnes and volumes integrated with geology; daily to long-term horizons.

Drill and Blast Designer

  • Bench blast patterns: hole layout, loading and charging, detonation sequence, blast solids.
  • Underground ring and drill-and-blast patterns with drill rig parameters.
  • Reports, plans and visuals for crews; cost and volumetrics against targets.
4Underground optimisation

Stope Optimizer

Many possible stope designs, ranked by the value they recover above cut-off.

Stope Optimizer

  • Optimum stope designs for a range of underground mining methods.
  • Stope inventories from block models that spatially represent the mineralisation.
  • Designs that maximise recovered resource value above cut-off grade.

Practical parameters

  • Minimum and maximum mining width, anticipated wall dilution, minimum and maximum wall angles.
  • Outputs that feed straight into Mine Designer and scheduling.

Questions we get

GEOVIA Surpac FAQ

What is GEOVIA Surpac?
The world’s most widely used 3D geology and mine planning software. It covers drillhole data management, geological modelling, geostatistical analysis, resource estimation, mine design and production planning for open pit and underground operations.
Which roles do I need?
Most geology teams start with Block Modeler and Sectional Geology Modeler; engineering teams add Mine Designer, Drill and Blast Designer and, underground, Stope Optimizer; surveyors take Surveyor; everyone else who needs to view and share data takes Mine Contributor. ACALA scopes the mix with you before quoting.
What data can Surpac read?
Drillhole databases, point clouds, photogrammetric meshes, survey instrument files, and many formats from other mining software through data plug-ins.
How does Surpac connect to Whittle and MineSched?
The Surpac block model is the input to Whittle pit optimisation, and Surpac designs and reserves are the input to MineSched scheduling. The three form the standard GEOVIA open pit workflow, and ACALA supports all of them.
Does ACALA provide training and certification?
Yes. Corporate training is customised to your operation and delivered on site, in class, online or one-on-one by certified instructors. Participants receive completion certificates from ACALA and Dassault Systèmes.
How do I get a licence in Indonesia?
