Grid & Plane Setup window

Grid & Plane Setup window

This window is used to assess the event location and mechanism quality. As events move away from the seismic array, the relative location error for a given magnitude is expected to increase, as well as the confidence in the location accuracy.

This window is used to investigate tagged blast locations from the events database and compare them with the blast locations set in the Blasts table to determine potential accuracy or offset issues with the system. In order to conduct this analysis, you first need to have tagged blasts. For IMS users, this information isn’t imported automatically. Please contact them to obtain the event tags database. For ESG users, the tags are imported automatically. You will however need to verify the meaning of these events to make sure they pass the quality filter.

This window is set up to conduct sensitivity analysis based on the trendline fit obtained in the previous window. It allows you to exclude current sensors and add planned sensors to see how the sensitivity changes across your mine.

This window is used to set the different variables to calculate the trendline in your data to be able to do the sensitivity assessment. Simply follow the steps through the window menu at the top (see figure).

The System Design app is used for analysing the seismic system design (historical, current and future). It is set up with various tools to assess system sensitivity ($M_$) and location and mechanism quality. Follow the links in the Key Learning Process section for the documentation on each window.

Assists with seismic monitoring network planning, sensor placement optimisation, coverage evaluation, and system sensitivity assessment.

A key criteria when designing a seismic system is establishing the lowest magnitude that the system can reliably record ($M$), referred to as the system sensitivity. The $M{min}$ the system is designed for can vary in space and time as it will depend on the application of the system (Rock mass monitoring, Hazard assessment, Damage location).
