The blue area of activities in the flowchart describes the control measures (see figure below) that can be implemented to mitigate the seismic hazard, as defined in the previous eight steps of the process. Ground support and exposure controls aim at mitigating the consequences of seismic activity. These techniques are employed in all seismically-active mines. Changes in mine design and conditioning the rock mass aim to reduce the seismic hazard. These controls are generally more difficult to apply but, in some cases, can be very efficient in reducing seismic risk.
