rockmass-data-analyser-updates-1024x644
Rock Mass Data Analyser updates
The Rock Mass Data Analyser (RMDA) application allows a user to import various types of geotechnical data (rock mass quality, structural, stress and intact rock strength) into mXrap, creating a geotechnical database which may be visualised and analysed in 3D, on charts and in stereonets (see previous blog post for more details). Since the release of the RMDA, various updates have been made to assist with data analysis and setting up the rock mass database. Interface: The application is now split...

New tool - Datamine file converter
If you use Datamine at your site, we now have a tool to help you batch convert the datamine TR and PT files into mXrap-readable dxf files. To get access to this tool, please contact the support email address at our support email address.
Update to paste backfill design app
Update to Paste Backfill Design app
We have made a couple of changes to the Paste Backfill Design application since the original release. See the previous blog post for the main details of the app. Since the first release, we have modified the paste volume calculations to allow for multiple pouring locations and beach angles. This will be helpful for cases where there is an initial waste rock dump in the stope. The video below demonstrates a scenario where the stope is first filled with beach angle 37°, then filled with material...
NEW APP paste backfill design
NEW APP – Paste Backfill Design
We have developed a new app to aid in the design of paste backfill in stoping operations. The app has tools to help you to: Calculate paste fill volumes and bund capacities, Assess the fill stresses and stability for vertical and horizontal exposures, Analyse UCS test results and fit a strength prediction model, and, Assess the pressure and friction profile of the paste reticulation path. If you would like to try out the app, please contact our info email. Paste volumes The paste...
rock mass data analyser
Rock Mass Data Analyser
The Rock Mass Data Analyser (RMDA) application allows a user the ability to input various types of geotechnical data into mXrap, creating a geotechnical database of borehole and mapping data, which may be easily visualised and analysed in 3D, on charts and in stereonets. Thus far, the application has been developed to allow for the visualisation and assessment of: Rock mass quality data e.g. RQD, RMR, Q, Q’, GSI etc. Structural data i.e. joint orientations and joint conditions from scanline...
updates-to-large-event-analysis
Updates to large event analysis
The Large Event Analysis app has receieved a number of upgrades recently. These upgrades focus on analysing seismicity in the immediate time before/after a large event. A new window, called ‘plane based analysis’, allows the user to investigate the source parameters around the location of an event before/after it occurred. The analysis conducted is the same as that of the planes in grid based analysis, however the time period is centred around the event time. The planes locations can...
updates to grid based analysis
Updates to the Grid Based Analysis app
There are a number of updates to the Grid Based Analysis app. The first is the ability to use multiple planes for analysis instead of just a single plane. You can also now choose up to two dynamically generated planes, instead of just the saved planes. There is a new chart called ‘grid results distribution’ which gives both a histogram and cumulative distribution of the grid results so you can dig further into your results. The last is a streamlining of the ‘advanced’ features....
grid based analysis parameters
Grid Based Analysis parameters
The Grid Based Analysis application can be used to evaluate the spatial distribution of various seismic parameters. There are a range of source parameter options available, and they can give indications to the rock mass behaviour. Some parameters can be considered as a proxy (stand-in) for rock mass stress, while other parameters can be a proxy for the amount of deformation. There are also parameters available that are associated with the rock mass mechanism or event type. In grid-based analysis,...
updates to hazard assessment app
Updates to Hazard Assessment app
A few new features have been added to the Hazard Assessment application, aiming to improve usability, understanding and investigation. The first addition is a chart in the hazard setup window to indicate the current date range settings. Usually the date range for calculating b-value will be a lot longer than for calculating event rate. Hopefully the chart will be a handy visual aid to help you keep your bearings when setting the hazard analysis periods. There are also two new windows under the “Hazard...

Deswik survey support
The mXrap survey import tool now supports files saved in Deswik’s VDCL and DCF formats. There is also preliminary support for the Deswik Unified File format (DUF), but currently only for DUFv1. We recommend either VDCL or DCF as the most reliable formats for use with current versions of mXrap. If you’re currently exporting surveys to DXF for use with mXrap, either VDCL or DCF should provide a significant saving in terms of disk space and be faster to load into mXrap’s survey cache. As...
mine geometry model minode generator
Mine Geometry Model - Minode Generator
Mine Geometry Model Minode Generator is a new utility app which enables you to generate your own new minodes from a mine geometry model. If you’re not sure what minodes are or why you would want to generate them, see What are minodes? (note: that post describes the old procedure for getting updated minodes, but with this app you can update minodes yourself without needing to wait for us). If you’re not sure what mine geometry models are, see Mine Geometry Models Application. The minode...
plane based analysis
Plane based analysis
The Grid Based Analysis now has a plane based function. The user can select a plane (defined in the plane editor window) and display cumulative or average parameters on that plane. Like the grid, the average and cumulative parameters are calculated differently. For the average parameters, the plane points are treated identically to the grid – the events around each point are found and the average parameter is calculated (the plane is essentially a 2D grid). The cumulative parameters are calculated...
analysing seismicity around large events
Analysing seismicity around large events
A new window has been added to analyse seismicity in the Large Event Analysis application. In a similar approach to the Short-term Response Analysis app, events are assigned to large events based on a spheroid volume and a time range before and after the large event. The chart below shows the energy index of seismicity for 24 hours before and after 156 large events. The time of the large event is indicated by a vertical, dotted black line. If a large event had a blast or another large event in the...
new hazard charts in general analysis
New hazard charts in General Analysis
Two new charts have been added to the General Analysis application related to assessing hazard with the frequency-magnitude relationship. The new charts plot various hazard parameters over time, or, by time of day:                 Charts / Time Series / Hazard over Time                 Charts / Diurnal / Diurnal Hazard The following parameters can be plotted in each chart (maximum two at a time): Mmin – The magnitude of completeness. The magnitude, above which the dataset is complete. b-value – The...
background filters in the hazard app
Background filters in the hazard app
The new background filters have been added to the Hazard Assessment application. The time of day filter can be used to see the effect of removing events during blasting/shift change on the hazard results. You can either view the results in raw or normalised form. The hazard calculations do normalisation for the event rate calcs anyway, to represent hazard in yearly terms. If your analysis period is six months, the number of events is doubled to represent a year’s worth of events. When applying the...
stochastic declustering explained
Stochastic declustering explained
As mentioned in the last blog post, a stochastic declustering algorithm has been implemented in mXrap to separate events into ‘clustered’ and ‘background’ components. It can be useful when designing seismic exclusions and re-entry procedures to separate seismicity that occurs in short bursts from seismicity that has low variability in space and time. Short-term exclusions cannot be used to manage the risk associated with background seismicity, since the hazard inside a potential exclusion would be...
new background filters
New background filters
We have added some new event filter options to general analysis related to ‘background’ activity. ‘Background’ events are generally defined as having low variability in space and time. The new background filters aim to identify events that are clustered in space and time and the user can either display the ‘clustered’ or the ‘background’ component of seismicity. There are three ways of classifying clustered events; by time-of-day, by proximity to blasts and significant events, and by a stochastic...
