Geophysical investigative techniques can be a valuable supplement to standard subsurface investigations for the evaluation of abandoned underground coal mine workings and their potential impacts at the ground surface. The GUE 70 - 14.10 Mine Research Project is the investigation of a 2,1 OO-foot long section of Interstate Route 70 in Guernsey County, Ohio. Portions of the highway were damaged as a result of mine subsidence. The damaged areas and other mined areas beneath the highway were remediated in 1995 by placement of grout in the abandoned mine workings beneath the roadway. The intent of the research was to evaluate the effectiveness of investigative techniques at identifying subsurface conditions impacted by past mining activities. The work included the evaluation of geophysical, geotechnical, and hydrogeologic investigative methods in a highway setting typical of the eastern Ohio coal mine region. The geophysical methods evaluated included: surface ground penetrating radar (GPR); side looking GPR; cross-hole GPR; surface seismic methods; cross-hole seismic methods; resistivity, and geophysical borehole logging.
