• 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
  
  collapse of roads or buildings that overlie the
  
  voids. The resistivity response of air- or waterfilled
  
  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.
