A Borehole Radar System Design

In 1996 and 1997, borehole radar trials were conducted on a number of economically significant South<br>African mining targets, using the Swedish MALÅ RAMAC system. Surveys targeting the Ventersdorp<br>Contact Reef (VCR) were particularly successful (Vogt et al., 1997). At the time, the Ramac system did<br>not function at the temperatures encountered in deep level gold mines but the success of the technique<br>convinced the DEEPMINE collaborative research programme to fund further work, with a radar system<br>provided by Prof. Iain Mason of Sydney University.
