Over the last three decades, employment of geophysical technologies applied to coal has been limited in scope when compared to the petroleum industry.  This is largely due to several key factors; namely, limited or lack of capital by mining companies, lack of exposure, inexperienced geophysicists, and more complexity. Thus, the subject of coal geophysics remained largely unknown or mysterious to the geoscience profession and industry. 

From 1985 to 2000, Gochioco built the country’s only multi-faceted coal geophysics program at the R&D Department of Consol Energy Inc. (former Conoco Coal Research Division).  Consol Energy Inc. was the country’s second largest coal producer and world’s largest operator of underground longwall mines. The coal geophysics program was developed to enhance the operations and safety of company mines. Various geophysical methods (seismic, electrical resistivity, electromagnetics, VLF, ground-probing radar, etc.) were developed and employed to address the complex upstream and downstream challenges of coal mining.

Case studies will be presented to highlight the benefits of properly-executed geophysical projects that provided solutions to address problems associated with the exploration, engineering, and environmental issues. According to the EIA, global coal consumption is anticipated to increase by 50% by year 2030 as coal is considered a cheap and abundant fuel.  The speaker will present his recent international exploration exploits in countries where they are rapidly developing their domestic coal reserves and making it more competitive in the global fuels market through the employment of advanced remote-sensing technologies.
