Map3D Versions

* larger capacity available if requested

Map3D Modeller - features 3D CAD and Visual Database capabilities.

Included with all versions of Map3D.

Easy to use 3D CAD (OpenGL based graphics) system includes free-hand sketching or object picking to build and edit 5 basic entity types:

•3D blocks (e.g. stopes, ore zones, dykes, tunnels),

•2D features (e.g. faults, tabular mining, topography, fractures)

•grid planes (e.g. cross-sections)

•grid lines (e.g. bore holes, ground support)

•construction lines (e.g. survey data, drift centre lines)

Includes a full sweet of editing functions including copy, move, stretch, flatten, scale, rotate and more. Full dxf and pnt import/export capability to exchange data with other CAD programs.

The visual database can be used to display a database of any desired information including seismic or geologic information such as grade, rock mass quality etc. 3D points can be tagged with a series of:

•numeric values (e.g. colour, magnitude, orientation etc.),

•keywords (for filtering),

•text messages,

•file names (e.g. graphics files, documents, spreadsheets etc.).

Display of these items can be filtered in various ways. The location of each point can be displayed as colour shaded spheres or squares. The size and colour can be scaled according to various combinations of parameters. Point magnitude density can be contoured on a plane according to a user defined density function. A best-fit plane can be fitted using linear-regression.

Map3D Results Viewer - features stand-alone viewing of stress analysis results.

Included with all versions of Map3D.

Includes the visual database but not the CAD system.

•views stress analysis results generated by any of the Map3D analysis codes

•displays contours on cutting planes, along lines and at specific points

•user defined contouring functions

•direct ink to Excel for plotting x-y graphs

•display of 3D trajectories

•display of all stress, strain, displacement and strength parameters including principal components and resultant values on user defined planes and lines.

•export in dxf and pnt format for compatibility with other CAD and display systems

•probability of failure contours

•safety factor contour

•light source shaded models

•topographical contours

Map3D Fault-Slip - adds elastic rock mass and fully plastic fault-slip stress analysis capabilities.

Includes the 3D CAD modeller, the results viewer and the visual database.

The stress analysis utilizes the BEM (boundary element method) and has many features:

•the ability to analyze very large problem sizes (one million degrees of freedom)

•full 3D complex excavation shapes

•multiple elastic zones with different moduli (stiff dykes or soft ore)

•zones with different pre-mining stress state

•tabular mining with yielding pillars

•discrete non-planar fault planes that slip and dilate elasto-visco-plastically (including creep)

•multiple mining steps (40)

•automatic intersections allowing for excavations and faults to cross and overlap

A demonstration version of Map3D Fault-Slip is available at no charge. All features are available except the user is only permitted to run small size problems. This version is extremely useful for teaching the fundamentals of modelling and 3D CAD.

Map3Di Integrated Seismicity - allows one to superimpose external field loading effects into the stress analysis.

Includes all capabilities from Map3D Fault-Slip and adds the field loading effects. The field loading can come from thermal heating, fluid pressure, non-linear behaviour and deformations indicated by seismicity. These effects can be used to characterize geologic features, accommodate changing lithology and incorporate seismic loading effects into the stress analysis.

Map3D Thermal-Fluid Flow - adds thermal stress - fluid flow analysis.

Includes all capabilities from Map3D Fault-Slip and adds simultaneous solution of steady state thermal stress - fluid flow. The program is set up so that the user need only specify the temperature/head boundary conditions, then the thermal stress problem is solved simultaneously. This feature is useful for simulation of heating/cooling effects and drained/undrained response.

Map3D Non-Linear - adds non-linear rock mass response.

Includes all capabilities from Map3D Fault-Slip and adds the capability for the 3D rock mass to yield to loads that exceed the rock strength, and deform non-linearly to dissipate the excess stresses. This feature is useful for simulation of thick seams, over-stressed pillars, abutments, backfill and creep response. This formulation solves the non-linear problem on the surface of the boundary elements and interpolates these effects between these boundaries. This represents a first approximation to inelastic modelling that boasts the advantage of large problem sizes and very fast execution speeds.

Map3D Visco-Plastic - adds 3D elasto-visco-plastic rock mass response (still under development - not available commercially at this time).

Includes all capabilities from Map3D Fault-Slip and adds the capability for the 3D rock mass to behave elasto-visco-plastically. This model features a full solution of the non-associated incremental plasticity equations and adds the capability for the 3D rock mass to yield to loads that exceed the rock strength, and deform non-linearly to dissipate the excess stresses. This feature is useful for simulation of thick seams, over-stressed pillars, abutments, backfill and creep response. This formulation solves the non-linear problem throughout the rock mass.
