Biography

Lindsay is a consulting geophysicist to SRK with 26 years’ combined experience in the processing and interpretation of seismic waves ranging from: acoustic emissions recorded in the laboratory; seismic surveys for geotechnical purposes; seismicity induced by shallow and deep level mining; and, seismic reflection data. She was recently appointed as an Honorary Professor: Seismic wavefield simulation at the University of the Witwatersrand. Lindsay has applied state-of-the-art seismic interpretation technology to extract information vital to shaft-sinking, optimal borehole siting and mine-planning. She has specialist skills in determining seismic source mechanisms (laboratory tests in rock and concrete and mining seismology) through moment tensor inversion using her own code and expertise in dynamic numerical modelling (2-D and 3-D) of seismic waves for AE/NDT laboratory tests; mine-seismology problems; geotechnical problems; shaft-sinking, and reflection seismology. She has recently extended her dynamic modelling skills and has developed methods to model complex blast patterns for open pits and underground using Wave3D, a 3D finite difference full waveform modelling code.

Since joining SRK, Lindsay has become involved in seismic hazard assessments for the design of engineering structures. She has also begun to apply seismic and electrical methods to assess the internal structures of tailings dams, with a particular interest in quantifying brittleness.

Lindsay is an expert user and programmer in mXrap, a geotechnical data analysis and monitoring platform within which data analysis tools have been developed under the ACG’s Mine Seismicity and Rockburst Risk Management project.
