Level 2 Training – Basic User

 

Welcome to Level 2 of the mXrap software training programme. You should be familiar with the basics of General Analysis from Level 1 training, now we’ll continue to go through more features of General Analysis.

Legends

 

The first video in Level 2 concerns legends, which are present everywhere you go in mXrap. Learn how to display legends and configure the appearance for different 3D views, charts and tables.

Volume Specific Filtering

 

Introduction to volume specific filtering, how to show your volumes in the 3D view and apply the volume filters to events and blasts.

 

 

Video Thumbnail
VSA Charts

 

There are a number of charts for Volume Specific Analysis (VSA). This video shows one of the VSA charts for Cumulative Apparent Volume.

VSA Table

 

There is a summary table to monitor all of your volumes. The VSA table lists all of your volumes and highlights those with elevated recent activity. There are also probabilistic hazard calculations for each volume.

Selection boxes

 

Introduction to selections. How to make a new selection in 3D views and charts, and/or multiple selections, highlight or show only selections controls. Remember the Quick Reference Guide is handy to remember the controls for adjusting the selection boxes.

Selections in Base filter

 

How to use selections in the main events filter. You can show only selected in the tool where you have made the selections, but for the selections to affect other tools and calculations, you need to apply it to the base filter.

 

For more information on using selections, here is a recent blog post explaining how to use selections to filter events during periods of high apparent stress. Blog Post – Using selections in the event filter

Workspaces

 

How to use workspaces. Workspaces are available in every app and are used to save your current settings to be quickly used again at a later date. They are very handy to communicate things you’ve noticed to other members of your team or even to send errors you’ve notices to ACG.

 

Keep in mind that workspaces were introduced originally meant to be used only in the short term. We cannot always support workspaces through root upgrades so you might lose workspaces from time-to-time. Try not to rely on them in the long-term or be prepared to occasionally have to recreate them.

Pick Views

 

Picking is how you can find out more information about an event. You can pick in 3D views, charts and table views. This video shows you how to find out the details of an event in the 3D view using picking. See the Quick Reference Guide for help with picking controls.

Distance to Surveys

 

The distance to surveys feature allows you to filter based on distance to any surface. For example, you may be interested in events only within a certain distance to a fault.

 

 

 

Video Thumbnail
Survey Setup

 

You’ve been using surveys already but what if you need to update or add more surveys? This video shows you the survey setup window. This window is available in multiple apps, including General Analysis and General Setup.

 

You can import multiple different survey formats into mXrap. Blog Post – Survey formats

There have been some recent features added to the DXF importer to also bring in the colours and text included in the attributes. Blog Post – Recent updates to survey importing

 

Video Thumbnail
eXport panel

 

You can export any 3D view, chart or table view as a JPEG or PNG image. You can also export tables in CSV format. The eXport panel controls the image capturing and data exporting.

 

 

 

Video Thumbnail
Annotations tool

 

The annotations tool lets you draw arrows and lines in the 3D view. You can also use it to add labels and measure distances.

 

 

This blog post is about the introduction of the annotations tool.

 

 

Video Thumbnail
Monitoring Window

 

The Basic Seismic Monitoring application is intended for mine control room operators to monitor the latest seismicity and communicate event alerts and exclusion areas depending on site specific rules.

 

This blog post is about the introduction of the monitoring app.

 

 

 

Exercises

  1. Plot the EI-CAV for events within one of your volume filters
    1. Show the EI markers for the series and size by local magnitude
    2. Show the EI legend at the bottom of the chart
    3. Reduce the size of the marker in the legend to 0 (only show the colour bar)
  2. Find the volume with the highest long term hazard
  3. Find the Sensors table
    1. How many sensors are currently active?
    2. How many triaxial sensors do you have?
  4. Create two overlapping selections in 3D space
    1. Plot the FM chart for the AND results
    2. Plot the FM chart for the OR results
  5. Filter out events below 0 ML and pick 5 events in 3D
    1. Turn on all your faults in the Distance To panel
    2. Scroll through each event in the pick view to find the nearest fault and the distance
  6. Plot the cumulative event chart for >ML1 only
    1. Flick between the chart for “ALL” and >ML1 to see how they differ
  7. Create a fence (2D selection) in logE-logM
    1. Apply the selection to the base filter and view in 3D
    2. Split the window and plot the FM chart for those events
    3. Save this as a workspace
  8. Filter events out below 1 ML and show development surveys
    1. Use the ruler tool to find the distance between an event and survey
    2. Add labels for the event and survey locations
    3. Go to the eXport panel and save a .png with the 3D view, use high quality
  9. Open the survey setup window
    1. Add a new basic site survey and rebuild the cache
    2. Change the colour of the new survey
    3. Decimate by 50%
  10. Open the Basic Seismic Monitoring window
    1. Add an event to alerts
    2. Override exclusions to make an active exclusion area
    3. Isolate mining levels one-by-one to view the exclusion zone
    4. Dismiss all alerts

 

If you are familiar with the content above and completed the exercises, congratulations! You have completed the basic user training in mXrap. The next training level will finish off the last features of General Analysis and then expand into the other most used applications.
