Mine Seismology: Seismic Response to the Caving Process

Stefan N. Glazer has over 40 years of experience in the application of geophysical methods in the mineral prospecting and mining industry. He has been an independent mine seismology consultant since 2004, and before that he worked as a mine seismologist for AngloGold and then PMC. He holds an MSc degree in Prospecting Geophysics (1972) and a PhD degree in Mine Geophysics (1997), both from the AGH University of Science and Technology, Krakow, Poland. He has published a number of technical papers, the last eleven of which were on monitoring the PMC caving process. He was involved in the Mass Mining Technology 2 Project; in this regard he wrote on the "seismic signature of the caving process," which involved the analysis and interpretation of seismicity recorded at El Teniente, Chile, PT Freeport DOZ Mine, Northparkes Mine Lift 2 and PMC. The aim of this research was to make maximum use of the recorded seismicity to monitor and manage the caving process. In 2007 and 2011 he lectured on the subject of Mining Induced Seismicity for the Master Program in Geomechanics Applied to Mining at the School of Engineering, Universidad de Los Andes, Santiago, Chile. Between 1980 and 2012 Stefan published 19 papers, including 15 on mine seismology.
