The applicability of tunnel‐to‐tunnel electrical resistance tomography (ERT) for imaging
disruptive geological structures ahead of mining, in an igneous platinum mining …

In borehole radar (BHR) surveys, if the radar is either suspended by a conductive
communication cable or run in a conductive water, guided waves may be induced. When …

Application of ground‐penetrating radar has been successful in delineating gem‐bearing
zones in the Himalaya pegmatite mine of the Mesa Grande district of southern California …

A modified 2-D reverse-time migration algorithm in the energy flow domain, called EF-RTM,
is proposed for short impulse borehole radar (BHR) imaging. The key of the approach is …

A large portion of South Africa? s gold reserve comes from the Ventersdorp Contact Reef
(VCR). The VCR is a thin, tabular ore body, generally less than 1.2 m thick. The geometry of …

Borehole radar is an electromagnetic tool that can be applied to assist in the delineation of
orebody geometry, ideally using routinely drilled cover and exploration boreholes …

This book provides the basic know-how and guidance to effectively exploit non-destructive
geophysical technologies and apply them in the underground mining environment to …

We examine whether directional borehole radar while drilling is a feasible method to detect
the fluid interface that forms when mud filtrate invades a permeable layer. This interface …

It has been shown previously that borehole radar is a suitable tool for mapping the
Ventersdorp Contact Reef (VCR) and other thin tabular orebodies in South African gold and …

First arrival travel times (FATTs) from critically refracted waves in crosswell radar
applications have been known to cause incorrect estimates of electromagnetic wave …
