Presented by Dr Dave Collins and Dr Yuzo Toya, ESG Solutions, the purpose of this workshop is to demonstrate how seismic data from any type of mine site can be used to help understand the rock mass response to excavation. Underground mining continues to reach for minerals deeper in the Earth and to develop more aggressive mining methods, both of which significantly contribute to higher stress levels and therefore elevated seismic activity.
Today’s high accuracy seismic technology provides a database with a large magnitude range including many smaller magnitude events from which trends can be assessed to help explain the rock mass reaction from small scale fracture initiation to large fault slip. The advanced analysis of a single event or a cluster of microseismic events has become one of the main tools incorporated into rock mechanics analysis and mining strategies. Event source mechanism stress inversion analysis and the benefits to stress model calibration will be presented and discussed.
This workshop begins with a short introduction to seismic concepts, followed by practical examples of seismic analysis methods. Attendees with laptops will be provided with a short term licence version of ESG software and an example dataset.
