Borehole radar imaging in tactical support of miners working in very narrow stopes

Abstract

Hitherto, Tx→Rx cross-talk has inhibited the profiling of shorter tactical probe-holes, drilled from stopes at shallow angles below reef. Now that recent component advances have shrunk bistatic radars, raising their close-in response without compromising long range performance, BHR designers are moving towards mapping face & hanging wall fractures in stope automatically at one hundredth the scale of reconnaissance, in part with proximity coupled blast & bolt drillrod guided radars.
