• Abstract:
  Electrical resistivity surveys were completed at two sites along State Route 32 in Jackson and Vinton Counties, Ohio. ; The surveys were done to determine whether the electrical resistivity method could identify areas where coal was ; mined, leaving air- or water-filled voids. These voids can be local sources of potable water or acid mine drainage. ; They could also result in potentially dangerous collap se of roads or buildings that overlie the voids. The resistivity ; response of air- or water-filled voids compared to the surrounding bedrock may allow electrical resistivity surveys to ; delineate areas underlain by such voids. ; Surface deformation along State Route 32 in Jackson County led to a site investigation, which included electrical ; resistivity surveys. Several highly resistive areas were identified using axial dipole-dipole and Wenner resistivity ; surveys. Subsequent drilling and excavation led to the discovery of several air-filled abandoned underground mine ; tunnels. ; A site along State Route 32 in Vinton County, Ohio, was drilled as part of a mining permit application process. A ; mine void under the highway was instrumented with a pressure transducer to monitor water levels. During a period ; of high water level, electrical resistivity surveys were completed. The electrical response was dominated by a thin, ; low-resistivity layer of iron ore above where the coal was mined out. Nearby overhead powerlines also affected the ; results.
