Abstract

Subsurface coal heating poses a significant problem in many coal mines. The identification of the exact location of the heatings that occur in often inaccessible locations several hundred meters deep in goaf areas is a key to allowing effective control measures to be taken. Detailed investigations were carried out to apply the surface-based ²²²Rn technique to locate subsurface coal heatings in Australia. The results of two field trials indicated that subsurface coal heatings, at depths up to 450 m, lead to isolated ²²²Rn anomalies on the surface vertically above the heating zones. The geogas microbubble model for ²²²Rn transport through strata appears to be most in accord with the results of the field trials.
