Mine Geometry Models
Overview
The Mine Geometry Models application provides a comprehensive workflow for creating time-varying 3D models of mine excavations. The app operates through a three-window workflow:

Key Learning Process
Workflow Structure
- Survey Loading - Load and prepare survey data from your mine geometry
- Build Steps - Convert individual surveys into geometry blocks with temporal and categorical attributes
- Generate Models (Merge Steps) - Merge steps chronologically to create complete mine geometry models
- View & Save- Visualise models and export to various formats for analysis or numerical modelling
- Export- Visualise models and export to various formats for analysis or numerical modelling
Workflow Efficiency
- Create steps in batches for similar excavations
- Save models with descriptive names indicating resolution and content
- Cache your primary model as the master for mXrap integration
- Regularly update your master model as new surveys become available
A webinar has been held covering this app, click here to listen to the replay.
The application transforms static survey data into dynamic 4D models (3D space + time) that automatically update based on date filters. This enables powerful time-based analysis capabilities throughout mXrap.
How to use it in other mXrap apps
Once you cache a model as your master model, it becomes available throughout mXrap with powerful time-aware capabilities.
- Integration in General Analysis - Use geometry models for time-varying analysis in General Analysis
- Generating Minodes from the model - Generate minodes from mine geometry models for hazard assessment. Mine geometry models can be used to automatically generate minodesfor hazard assessment applications. The Minode Generator app processes geometry blocks to create centerlines through development excavations.
The image shows how development blocks are thinned to create lines through the center of excavations, with calculated effective span and height at each point. These minodes can be time-filtered to show only development present during specific assessment periods.
