High resolution seismic reflection techniques applied in coalfields: Cook Colliery, Queensland – A case history

Abstract

High resolution seismic reflection methods have been applied in Australian coalfields since 1978, with the aim of locating small faults and other geological features which may be hazardous to coal mining. BHP conducted a seismic reflection campaign over the Cook Colliery during the period from 1978 to 1980 when a total of approximately 90 line km were completed. The seismic survey detected a number of faults with complex geometry and made it possible to construct a more detailed map of colliery structure than was previously possible. In addition, by comparison with borehole data, it was possible to correlate reflections with particular coal seams and identify areas of seam variation and splitting. The Cook Colliery case history clearly demonstrates a role for seismic reflection techniques in colliery exploration and development.
