Geophysical surveys at a reclaimed mining site in Scotland

An integrated geophysical survey programme using magnetic and electromagnetic techniques was undertaken at Lochore Meadows Country Park, Fife, UK, the site of a reclamated colliery where recent ground subsidence has been a problem. The objectives of the geophysical survey were to test if geophysical techniques could be used to determine areas where ground instability existed as a result of the previous mining activities and subsequent reclamation. The Magnetic and Electromagnetic survey results showed geophysical signatures that were correlated with site plans showing manmade structures and potential cavities in the subsurface associated with the colliery workings.
