This talk is being presented by Junichi Sakakibara for ASEG Queensland Branch.
High resolution seismic cross-hole tomography has been developed and carried out for the purpose of detecting position and displacement of a fault in a coal seam. Faults with 3m displacement in the coal seam were clearly imaged by velocity and attenuation tomograms as a slower velocity and lower attenuated part, however, detection of this type of small fault were considered to be difficult by conventional seismic method. Spatial resolution of this investigation was expected to be less than 2m because transmitted wave frequency from the transducer was 1 kHz.
Junichi Sakakibara graduated from the University of Nagoya with a Master’s Degree in Geology 1990. He later obtained his PhD in Geophysics from Waseda University in 2013. He has been working in acoustic tomography at JFE Civil since he graduated. He started as a researcher, then became Group Leader and now is the General Manager of Technical Development. Junichi has extensive experience in the engineering industry and wishes to bring this expertise to the coal industry where JFE have an active interest in the Bowen Basin.
