Consequently, unlike earthquakes, the seismic rock mass response to mining can be controlled to a certain degree. The main objective of our fundamental research programme is to understand these control parameters and their limitations.
The main thrust of the applied research is to support the following objectives of seismic monitoring in mines.
- To quantify and to explain the difference between the observed and the expected seismic rock mass response to mining.
- To confirm the rock mass stability related assumptions made during the design process and enable an audit of, and corrections to, the particulars of a given design while mining.
- To quantify and to monitor seismic hazard.
- To detect strong and unexpected changes in seismic rock mass behaviour.
Applied Research also covers our Rock Physics programme, which aims to routinely use other geophysical techniques to monitor the rock mass response to mining. These techniques include the use of controlled, repeatable seismic sources to make routine high-precision measurements of seismic velocities in different zones of the mine. This is known as Active Seismic Monitoring
Applied Research contains another programme called Numerical Stress Modelling, which aims to combine the 3D seismic event data of where the rock is actually failing with the mine geometry and resulting stress fields contained with numerical stress models.
