High resolution seismic for resolving coal seam structure in difficult terrain

Abstract

This paper describes a high-resolution seismic survey in the Southern Coalfields of New South Wales over rugged terrain in areas yet to be mined. The aim of the survey was to identify faults in the working seam, which are very disruptive to longwall mining operations. Rapidly changing topography with deep gorges, swamps and dense bush create access and environmental difficulties for seismic operations. For the first time, attempts have been made to acquire seismic data across difficult gorge and swamp country. The techniques used were successfully adapted from previous surveys carried out in less difficult terrain. Current indications are that there will be minimal impact on the environment. The data collection and processing parameters developed enabled good coherent data to be obtained across deeply incised terrain. Faults with various throws have been interpreted.
