The recently developed in-seam seismic method is applied underground on the coal face itself. The area ahead of that currently being mined is investigated and it is possible to detect small but important faults that are not detectable from the surface. The combined approach gives both small- and large-scale structure.
Coal mining geology embraces a number of special skills and ... Broad-scale regional assessments based on literature survey, interpretations of air photos or satellite imagery, and perhaps regional field mapping, may not require a ... Survey control for such maps requires the establishment of accurately positioned ground stations.
Earlier experimental 3D seismic surveys for coal exploration Hatherly, 1991 showed that faults with throws of 4 m could be resolved. It was hoped that this survey, the first production 3D survey shot for coal mining in Australia, could provide similar resolution. Figure 2 shows the detail of the shot and receiver lines.
