Application of borehole radar to South Africa's ultradeep gold mining environment

Borehole Radar has been identified as the most immediately applicable electromagnetic technique to delineate disruptions to gold reef in the South African DEEPMINE environment. The economically important Ventersdorp Contact Reef (VCR) has successfully been imaged over ranges of up to 95 m and with resolutions of less than a meter, using the Geosonde system with a center frequency of 60 MHz.© (2000) COPYRIGHT SPIE--The International Society for Optical Engineering.
