Abstract
A newly developed spectrometric borehole logging tool (ZERO PROBE) has undergone several field tests on black coal deposits in Queensland an d New South Wales. The results of these tests are presented in the pap er. The ZERO PROBE utilizes a Cs-137 gamma-ray source with a strength of only 1.1 MBq, which is three orders of magnitude less than the sour ce activities applied in standard commercial borehole logging tools. T he field tests have proved high bed resolution of the ZERO PROBE for c oal seam delineation, and also, the probe's suitability for quantitati ve coal ash determination.
