Abstract:It is estimated that approximately 8,500 abandoned underground mines are present in Ohio and mine-related
subsidence has been a problem dating back to the 1920's. Many investigative methods have been utilized with
varying degrees of success in an attempt to characterize the mines and the stratigraphy above the mined intervals.
The primary objective of the research was to provide an overview of and guidelines for the implementation of
geophysical investigations of sites where highways are constructed above mines.
The geophysical methods tested as part of the project included: surface seismic reflection; spectral analysis of
surface seismic waves; cross-hole seismic measurements; surface ground penetrating radar (GPR); side-looking
GPR; cross-hole GPR; resistivity, and borehole geophysical logging. Based on the work completed, it is believed that
surface GPR, resistivity, surface seismic reflection using shear waves, geophysical logging, and cross-hole GPR can
be valuable supplements to the investigation of mines beneath highways.
It is noted that abandoned mine sites cannot be fully characterized by use of geophysical methods alone. The
characterization and evaluation should also include: a review of available data; a site reconnaissance by personnel
familiar with mine subsidence; site characterization by drilling and sampling; and, intrusive investigation of specific
areas of high concern. Furthermore, interpretation of geophysical data is an iterative process between the drilling
program and the geophysical investigations. The drilling data improves the interpretation of the geophysical data,
and the improved interpretation should be applied to re-direct the drilling progam.
