Application of 3-D seismic attributes analysis to mine planning: Target gold deposit, South Africa

摘要

Major South African gold-mining companies have recently turned to 3-D seismic surveys for mine planning in Witwatersrand Basin (e.g., Pretorius et al., 1997). We present examples showing that 3-D seismic data provide the gross structure and depth of the prospective stratiform ore horizons (the original objective of such surveys), and that careful analysis of 3-D seismic attributes—backed up with borehole control, direct geologic observations, and synthetic seismograms—can provide important information on small-scale faulting (throws of 10-20 m) and lithologic variations of the ore-zone conglomerates.
