Abstract
B034 MINESHAFT DETECTION IN THE BUILT ENVIRONMENT USING 3D ELECTRICAL RESISTIVITY TOMOGRAPHY 1 Summary A 3D surface electrical resistivity tomography (ERT) survey of a mineshaft is described. The work was commissioned by the Coal Authority (CA) as a component of a wider research programme designed to investigate the suitability of a range of geophysical techniques for the detection of hidden mine entries. In this case a built environment site (Site D) was selected which contained a backfilled mineshaft. The survey was intended as a blind test of the 3D ERT surface technique so the surface of the site had been
