• 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.
