Seismic Analysis and Interpretation for Mining

Overview:

Today many underground mines and some open pit mines install and use seismic monitoring systems to track seismic activity on a daily basis. However the information in seismic data, often, is not used to its best capacity. Recent advances in technology and seismology techniques have enabled the extraction of more detailed information from full-waveform seismic data that can better explain the rockmass behavior. This additional information can be used in a variety of geotechnical tools and analysis. This workshop discusses techniques for standard and advanced seismic analysis and their application covering topic such as: Ray tracing and event location for simple and complex media such as
block caves, backfilled areas and open pits, identifying trends in seismicity and their potential sources (which can be used in the identification of geological structures in inaccessible areas of the mine), advances in re-entry protocols following larger magnitude events and stress distribution analysis using seismic source mechanisms.

The purpose of this course is to demonstrate how standard and advanced seismological techniques and the history of seismic data can be used to take the most value out of a seismic system and gather more information from the recorded mine signals. Seismic results such as more accurate relocations and source mechanisms (moment tensors) determined from full waveform data can be used to better interpret the rockmass reaction to mining, and use this additional database in geotechnical models and analysis.

This workshop targets geotechnical and mine design engineers, ground control specialists, researchers, or anyone who has some knowledge about basic seismic monitoring and is interested in learning about the seismic analysis techniques and how the results can be used in mining operations to assess hazard and improve safety.
