A Map3D analysis proceeds in five stages:
Stage 1 – Model building and editing
This stage is used to setup the Map3D analysis.
The user can add new mining blocks and edit existing blocks using the CAD functions built into Map3D. This can include tunnels, large irregular shaped excavations, ore zones, massive and tabular excavations, open pits, faults, fractures and more.
Various parts of the model can be saved in separate component files and merged for final analysis.
At this stage, material properties are assigned and the desired mining sequence is set up. This can include ore placement, excavation and backfilling.
Field point grids are positioned at locations where off reef results are desired. For the case of tabular excavations, often only on reef results are required and hence field points grids are optional.
Stage 2 – Contact and intersection analysis
Intersections are built between blocks that cut through one another. Boolean operations are performed to resolve the mining sequence. Comprehensive model integrity checking is conducted.
Stage 3 – Block and grid discretization
The model is discretized into boundary elements to be used in the BEM analysis. The user has complete control over the way in which the model is discretized. This can be conducted automatically by the program concentrating results only where results are requested, or specified manually.
Stage 4 – Map3D BEM analysis
Conducts the Boundary Element Analysis. The same input data can be used for elastic, thermal/fluid flow or non-linear analysis
Stage 5 – Post-processing
This stage is used to view and process the Map3D analysis results. Contour plots of stress, strain, displacement and strength factors, or any desired combination of these components can be generated on boundary surfaces and on user defined field point grids. Results can be displayed either as total values, or the difference in value between mining steps.
Results from previous analyzes can be loaded for viewing
