Good quarry design depends upon a ground model that reliably defines the quality, volume and spatial distribution of resource and waste. Most ground models are based on boreholes, sometimes with additional 2D or 3D control provided by ‘traditional’ geophysical surveys such as microgravity, resistivity and active seismic. However, for logistical and economic reasons, these may not always be practical options for site investigations.
A new article published by some authors from the British Geological Survey showcases ‘passive’ seismic survey as a rapid alternative means of imaging the subsurface.
