The root upgrade that coincides with the software upgrade beyond v5.9 includes a new app for creating and exporting models of mine geometry. Stope, cave and development geometry is a fundamental aspect of most geotechnical analysis. Mine geometry also varies over time and capturing these changes is critical in any back analysis or numerical modelling that investigates stability or monitoring parameters over time. This is a utility app to create models of mine geometry that can be exported to facilitate a wide range of applications such as:
- Live Surveys — Mine geometry can be displayed as surfaces in General Analysis and other 3D views that automatically update with the current time filters. So when you backdate your seismicity to a year ago, the surveys will only show geometry present at the time.
- Volume Calculations — Mining volume can be calculated over time. This allows seismicity and other parameters to be plotted as a function of mine geometry.
- Distance Calculations — It is often important to know the distance of large events or damage locations to the nearest development or stope at the relevant time. This is like the distance to survey tool except time is also taken into account. So you can compute the closest stope at the time of damage or the closest development at the time of the large event.
- Numerical Modelling Inputs — The geometry models can be exported in a number of formats, including Map3D .inp format.
The export options will gradually be expanded to more modelling formats such as FLAC, RS3 and Wave. Another possible application is to create block models of lithology or geotechnical domains based on lithology contact wireframes.
Training videos have been made to walkthrough the new app. See the page below.
We started making training videos about 12 months ago and feedback has been quite positive. At the last AGM, a suggestion came for a training programme aimed at new users to mXrap. The training videos are currently stored by app but a specific programme would help new users with a logical order for progressing through the training content.
We have made a new page for the Training Programme under the Training tab. The programme is structured in several user levels, from a basic introduction to General Analysis, moving through all the apps and finally to advanced app building tutorials. There are a few links to relevant blog posts and papers that will help users understand some of the analysis concepts. There are also exercise questions in each section for users to complete using their own data.
Most users are probably aware of the Quick Reference Guide in the Cheat Sheets. It lists all the mXrap shortcuts and hotkeys but it is spread over a few pages and can be a bit tough to find what you’re looking for. Below is a one-page Quick Reference Guide for more of a visual lookup of the main controls. The controls for the new Annotations tool are not included but help for those controls is available in mXrap itself. Here is the PDF version of the one-page guide if you want to print a copy.
You can now measure distances in any 3D view in mXrap (version 5.6.0 or later) with the ruler tool in the Annotations tab. The “Annotations tool” training video on the General and FAQ page goes through all the features and the operation. Most operations will probably be for the distance between two points, such as the event-to-survey distance below. You can also extend this to a multi-point ruler for measuring more complicated paths.
The controls are very similar to selection boxes. Control instructions are in the Annotations tab.
- Ctrl + Left-click to move/select point
- Ctrl + Right-click to rotate/cancel
- Space to insert a point
- Del to delete point
Other features include:
- Snap ruler to point or surface (crosshairs will turn from red to green when snapping)
- Point rounding – For selecting points on a grid or post-rounding
- User defined labels on vertices or segments
- Table of point coordinates, segment lengths, horizontal and vertical runs, trend and plunge
- Optional arrow head
- Save and load rulers
- Flatten points to the focal plane (view plane)
There have been some interface changes made to the mXrap software in versions 5.6.6 or later. The right-hand-side controls have had a bit of a face-lift and now there are separate coloured tabs for exporting, selections, annotations and clipping.
The 3D Controls button has also been moved above the series window and the buttons in general have had some styling. We are planning some further changes to Clipping and looking at combining the dynamic clipping controls with the Clipping panel.
The eXport panel is where you can control the screen capturing and table exports. This tab can be “popped-out” to make it easier to export many tools at once. Please note the “eXport panel” training video has been updated on the General and FAQ page.
