You can use selections to filter events in General Analysis. This gives you a lot more freedom than being restricted to the traditional min/max range filters. Follow the steps below to see how you can use this feature to plot the Frequency-Magnitude chart for events occurring during periods of high apparent stress.
You can also check out this page to watch the “Selection boxes” and “How to use selections in the base filter” videos.
Step 1 – Create a new selection on the Apparent Stress Time History chart. Note that selections can be made in any 3D view, chart or table in a similar way.
Step 2 – To apply the selected events to the filter, go to the Events Ranges panel, hit “Copy selections to Base filter” and switch on the selection filter below. Now only the selected events will be used in the Frequency-Magnitude chart.
Step 3 – To turn off the blue selection icons, go to the Events series and turn off the “Highlight selected” option.
Note that if you adjust the selection box or make another selection, you need to hit the “Copy selections” button again to apply the changes. Use the switch to turn off the selection filter and return to original filter.
In the case of the Apparent Stress Time History chart, selection boxes are applied to the frequency line rather than the events in the background. The series that is active for selection can be modified. Look for the “Select” option in the series controls on the right-hand panel.
Did you know that any 3D survey or surface can be displayed in Solid or Wireframe mode?
Hit “W” in the 3D view to switch to wireframes, hit “S” to switch back to solids!
Remember there is a Quick Reference guide in the cheat sheets for all the shortcuts in mXrap.
By now most of you have probably heard of mXsync. It has been installed at all the current sponsor sites and we did explain briefly as we went but there might still be some uncertainty about it.
mXsync is a piece of software installed separately to mXrap that facilitates the backup, restore and upgrading of the site root folder. We hope this new root folder management system will allow new and improved apps to flow more easily and more quickly to sites.
Right now we would like at least one person at each site to get to the point where they have mXsync setup on their computer and they are familiar with how to perform a backup. We’ve uploaded a video that gives a quick intro into mXsync and how to do a default backup. There are a few other videos on mXsync that show you some more operations that sites may need to do at some point.
For a few more details on mXsync, and some things that might be of importance for IT, please refer to the About mXsync page.
Please comment in the forum or contact us at firstname.lastname@example.org if you have any problems.
There are a number of quality filters applied to the event database before they are displayed in mXrap. This does sometimes cause confusion because a particular event is visible in your other software, but not in mXrap.
The most common cause is the location filter but there may be other reasons. Have a look at the “Event quality settings” video at the page below. It goes through all the quality filters applied at your site and how to change them.
As always, comment in the forum or email email@example.com for assistance.
The default event local magnitude marker might not suit everyone. After all, a ML+1.0 might mean something completely different to you compared with the site next door.
The “Change event marker style” video at the page below will run you through how to make a site specific event marker. There are a couple of other marker styles you can adjust too :)
If the video isn’t clear, please contact firstname.lastname@example.org or leave a comment in the forum.
We previously created a Basic Seismic Monitoring app but it didn’t get widely used. We’ve taken another swing at a new version released late in 2017.
The new app is intended for mine control room operators to monitor the latest seismicity and communicate event alerts and exclusion areas depending on site specific rules. Each site can setup their own event alert and exclusion settings in the Basic Seismic Monitoring (Admin) application and then the main application is a simplified interface for the viewer.
Key features include:
- Automatic events updating (no need to keep pressing “Reload Data”!).
- Popup event alert notifications (to alert user when window is hidden/minimised).
- Popup system alert notifications (triggered from threshold time without new events).
- Plot exclusion areas and isolate single mine areas (e.g. single level plans).
- Automatic View – quick zoom/rotate to the exclusion areas on screen.
- Distance measurement – get the distance from any survey point to the nearest event alert.
There are two videos uploaded at the page below; one to show you how to do the initial setup in the Admin window and another for the basic user in the main monitoring window. If your root looks different to the video, you might need a root update. The process is quick! Just contact support.
We are also working on a few more features for the app and will hopefully release another update soon in 2018. Additions should include:
- 3D text from DXFs
- Non-spherical exclusions (cylinder or box)
- Alternate event marker style
- Improved data reload speed
- Popup event query window (for source parameters)
- Enable/disable auto-clipping
- Event comments included in the table
If you have any questions or comments, feel free to email email@example.com or post in the forum.
The distance to survey filter has been around for a while but now we have added a couple of new charts to further investigate the relationship between seismicity and your input surveys. The charts have been added to the General Analysis application, under the Charts menu, look for Distance to surveys.
There is a training video to explain a few things about the charts, find it here: https://mxrap.com/training-videos/dist-surveys/
The example below shows how you can compare your seismicity around your geological structures. Of course, sometimes a structure will have a lot of seismicity nearby because you happen to do a lot of blasting nearby. You can also plot blasts as a function of distance to survey!
If you can’t see the charts in your mXrap, you might need a quick root update, ping us an email at firstname.lastname@example.org and we’ll sort it out. Now we’ve setup everyone with mXsync, updates are very easy, will probably only take 10 minutes on teamviewer/webex :)
What do you think of the new charts? Any ideas for additions or improvements? Comment on it in the forum or contact support!
If you want to learn more about mXrap, we don’t have a user manual to read. Who would want to read through one of those! We have been writing “cheat sheets” to show new users the main features of mXrap.
We’re still going to try and keep the cheat sheets updated, but we are going to focus more on our new training videos platform!
This is where we will post short tutorial videos to show and tell all the features of mXrap. Things like modifying clipping volumes, calculating hazards, using the gridding app will all be included. In time we will add more FAQ content and even some more advanced training material for those who want to play around with the guts of mXrap.
There is a link to the training videos from the mxrap.com website, look for the training tab. This is the direct address: https://mxrap.com/training-videos/
The training videos are password protected, ping us a quick email at email@example.com and we’ll send you the password. Please don’t share the training videos outside of the mXrap sponsor network.
Feel free to discuss in the forum, let us know what you think of the new page, any problems watching the videos and ideas for new or modified content.
Welcome to the mXrap noticeboard. As many of you noticed this last year, there is a lot going on in the mXrap offices. Many new members, and many changes to old software and the addition of the mXsync software. We know this can be a bit overwhelming, and that is why we decided to try this platform to record and communicate all these changes. We will update this noticeboard as much as possible, so if you want to know what is going on in our offices, just head over here and you will see the latest and greatest developments.
Also, there is a forum option here as well, so you will be able to ask questions and see questions from other users as well.
The mXrap Team
