Geophysical Void Detection Demonstrations Riola Mine Complex, Black Beauty Coal Company, Near Georgetown, Vermilion County, Illinois

摘要

ZAPATAENGINEERING P.A., Blackhawk Division (Blackhawk) was contracted by the U.S. Department of Labor's Mine Safety and Health Administration (MSHA) to conduct surface and borehole geophysical investigations to locate air- and/or water-filled voids associated with old mine works. The investigations were in support of MSHAs Geophysical Void Detection Demonstrations Program. The main purpose of this program was to advance the current state-ofthe- practice geophysical technologies for detecting underground mine voids that could potentially pose health and safety hazards to miners approaching old/abandoned mine works.
