Why are the event magnitudes different in mXrap?

There are many reasons you might want to store a short snippet of text associated with an event. There are two ways to do this in mXrap; event tags and event comments.

The export panel, located on the right-hand side of 3D views, charts and tables, can be used to generate images, files, and videos with just a couple of clicks.

Reset variables and filters

Survey input configuration

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.

Background filters

For a few months now, a new tool has appeared in the General Analysis app; the hanging wall (HW) and footwall (FW) filter. The HW-FW filter allows you to filter your events based on where they are in relation to ticked survey/s. If more than one survey or plane is used for the HW-FW filter, they need to be somewhat parallel in order to make sense.

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? If you're not sure what mine geometry models are, see Mine Geometry Models Application.

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:

This suite of apps provides tools for the analysis and interpretation of mining induced seismicity and the management of seismic hazard.

When trying to add, delete or change blasts in mXrap, best practice is to use the 'Blasts Editor' found under the 'General Set-Up Windows' tab

Where is the cumulative energy line on the Omori chart?

You know that energy and moment are parameters to describe seismic events. But what exactly is their physical meaning for a seismic event source and how are they calculated?

Data Anomaly Detection

Seismic activity rate monitor

A simple utility app has been added to the main root that can be used to export surveys loaded in mXrap. Possible reasons to use this app include:

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.
