Moment Tensor Axis Colour Update
For users that look at moment tensors, please be aware that we are changing the arrow colours and improving the legend. The colours of the moment tensor T and P axes have been updated to align with the colours used in ESG and IMS system: Red for the P axis Blue for the T axis […]
mXrap 6.1 – Release notes and Changelogs
Highlights This version brings several new features to mXrap 6, as well as a host of bugfixes and performance improvements. You will be prompted to upgrade by a yellow banner at the top of the Apps window. Follow the link to download and install. Full user changelogs for this version are available here. 3D Interactive […]
What are minodes?
Minodes are what we use in multiple places in mXrap if we want to assign information to development. They are just point locations, dotted along your development at regular intervals.
Using the ‘Minode Generator’ App mXrap users can create minodes using their Mine Geometry Model or survey files. Minodes are not generated automatically and should be updated periodically to reflect new development.
Grids
Grids are a dynamic tool used throughout mXrap to form seismic populations, perform calculations and display results. Taking time to set-up site appropriate grids not only makes performing analysis in mXrap more efficient, but it enables others to easily replicate your results. Most sites benefit from a mine and/or orebody wide coarse (sparse) and relatively dense grid, plus additional higher resolution (dense) grids for areas of interest.
Es:Ep Ratio Charts Have Moved
Es:Ep ratio charts can now be found in the ‘Parameter Distribution’ charts for the base filter (Charts > Parameter Distributions) and VSA’s (VSA > Charts > Parameter Distributions).
Select the EsEp option under chart controls to see the cumulative distributions for Es:Ep ratio.
Modifying the Imported Tags Meaning
Depending on your seismic monitoring system setup, you may be importing events with different tags into mXrap. When you open mXrap, any events with imported tags ‘b’ and ‘n’ are turned off by default and all other imported tags (e.g. ‘e’) are turned on. If your database contains other imported tags, you can change the meaning (GOOD, OUTLIER, or BLAST) using: General Setup Windows > Event Tag Editor > Imported Tag Meaning.
mXrap 6.0.6 – Release notes and Changelogs
mXrap version 6.0.6 is now available to all users. This release is focused on bugfixes and performance improvements and will be the final release for version 6.0.
Modifying Root Access in mXsync
Use mXsync to easily add and remove users from your mXrap roots.
Data Anomaly Detection
Anomalies often stem from default values, null entries, manual input or rounding mistakes. While many of these anomalies indicate bad data, not all do. However, if any data is found to be incorrect, it’s important to clear these values to prevent skewing your analysis. Our new Anomaly Detection window provides visualization tools to help you investigate any flagged anomalies and take appropriate action.
Hazard Assessment – Event Rate
The Hazard Assessment application uses a grid-based approach to describe the seismic hazard throughout your mine. Each grid point essentially represents a seismic source with a specific frequency-magnitude relationship. A frequency-magnitude relationship is defined from the MUL, Mmin, b-value, and event rate. The event rate is something we haven’t taken a dive into yet, so we’ll get into it in this post. Event rate sounds like a simple calculation but there are quite a few complexities worth explaining.
