In the mining industry, failure to recognize, understand, and respond to changes in the underground environment or geological conditions can lead to expensive and disastrous consequences. Some geophysical techniques that offer promise for noninvasive evaluation of the mine host rock include high-resolution seismic reflection and fraction; microgravity; ground penetrating radar (GPR); and electrical, electromagnetic, and magnetic surveys. Tomographic studies (seismic, electromagnetic, radio-imaging method, etc.) can be conducted through boreholes and mine workings; these studies can provide two- and three-dimensional views of the rock mass. The NIOSH Pittsburgh Research Laboratory is conducting research to evaluate off-the-shelf GPR technology for mining applications. In this paper, we present case studies of the use of GPR for the detection of adjacent mine workings, delineation of overburden conditions above a mine portal, and advance identification of anomalous geological features (roof fractures and joint-based solution channels).
