Application of ground penetrating radar for coal thickness measurement

Ground penetrating radar (GPR) represents a non-invasive sensing technique for subsurface imaging. This paper overviews an impulse GPR unit being developed and evaluated by the CSIRO for use in coal thickness measurement. The GPR unit has been designed to operate in an underground mining environment and so special considerations have been made to ensure that the radar equipment does not present a safety hazard. Data obtained from a field trial are presented as well as a preliminary data analysis.
