Not just for coal mining, for all mining… 

Technical Director - Thomas M. Barczak

TomBDr. Thomas Barczak recently retired from the National Institute of Occupational Safety and Health (NIOSH) where he served as the Director of the Mining Science and Technology Division within the Office of Mine Safety and Health Research. In this capacity, he was responsible for managing the research effort including the extramural contracts program to fulfill the requirements of the Mine Improvement and New Emergency Response Act of 2006, which was intended to promote the application of innovative and enabling technologies to improve mine safety. This effort has successfully introduced technologies such as refuge chambers and communication and tracking technologies, which have significantly increased survivability from potentially disastrous mining events.

Dr. Barczak has been involved in mining research for the federal government for the past 36 years working for the U.S. Bureau of Mines and the Department of Energy in addition to NIOSH. He is recognized as an international expert in the field of ground control, with over 100 publications on various ground control topics. He is most noted for his work in the design and testing of mine roof support systems, and served as the technical manager of the Safety Structures Testing Laboratory, which houses the Mine Roof Simulator. This complex load frame is designed to simulate the extreme weight and movements of the overburden rock masses, and as such is the most powerful and largest multi-axial load frame in the world. This world class facility provides unique capabilities to conduct research into roof support design and to evaluate new support technologies to ensure that they meet basic safety standards. Dr. Barczak has developed the testing protocols to accomplish these tasks and has worked to provide the mining industry with many valuable products to improve the health and safety of the nation’s miners.

Dr. Barczak also serves as the Executive Director for the International Conference on Ground Control in Mining, now operating in its 32nd year as a premier conference promoting advancement of ground control engineering and practical solutions for ground control problems in the mining industry. Dr. Barczak has also authored 28 publications in this conference.

Dr. Barczak graduated from West Liberty State College in 1975 with a B.S. degree in Physics and earned his M.S. and Ph.D. in Mining Engineering from West Virginia University in 2004 and 2005. He is an active member of the Society for Mining, Metallurgy, and Exploration.
