About the Flowchart

This Seismic Risk Management Practices flowchart has been developed and verified during the benchmarking exercise. The process has four major activities, each represented by a coloured area in the flowchart:

  • Data collection (purple)
  • Seismic response to mining (green)
  • Control measures (blue)
  • Seismic risk assessment (orange)
  • Within each activity, there are a number of components, represented by boxes in the flowchart. Within each box, a number of practices have been benchmarked and will be discussed in terms of being a “standard” or an “advanced” practice.

    Practice Levels

    Keeping in mind that the goal of the project was to define “best practices” in managing seismic hazard, it is also important to realise that best practice at a mine site is necessarily a function of the intensity of the seismic problem at that site. As such, it is not always necessary nor “best practice” for mines experiencing low seismic hazard to implement extensive and advanced seismological analyses. Hence low, medium and severe seismic hazard will call for different “best practices”.

    To circumvent this issue, in this benchmarking report, we will refer to standard and advanced practices. Standard practices indicate approaches commonly used at most mine sites. Advanced practices involve techniques that are uncommon due to:

  • requiring personnel with a high skill base; and
  • being labour/computing/time intensive.
