Abstract
The need to identify oversized fragments in underground mining operations is discussed. The relationship between relative permittivity and bulk density is examined using established mixture models. A method of measuring the relative permittivity of ore in an industrial context is presented using a two channel Ground Penetrating Radar system in a trans-illumination arrangement. This method also provides a solution to the problem of time zero drift which affects spatially and/or temporally separated antennas. Results of experiments using sifted samples of fragmented ore show there is a relationship between bulk density and relative permittivity for fragmented ore.
