The 2004 Rock Mechanics Award  

Awarded To: Frank L. Gaddy

“To honor a distinguished career spanning five decades focused on improving coal mine ground control, especially for his pioneering work that led to improved pillar design through a better understanding of the influence of size on coal pillar strength”
FRANK L GADDY, P.E., is the founder of Gaddy Engineering Company and was the President and Chief Executive Officer from December 1967 to March 2000. Since its formation in 1967, Mr. Gaddy has directed all aspects of the company’s engineering, geological, and natural resources management services. Included in these are: coal resource, roof control and mine feasibility studies; property appraisals; mine cost evaluations; and property management. A synopsis of his credentials for the establishment of Gaddy Engineering consulting services follows.

From 1959 to 1967, Mr. Gaddy was affiliated with the Chesapeake and Ohio Railway Company as a Mining Engineer and was promoted to the position of Assistant Engineer of Coal Properties in 1962. The position required extensive detailed investigations into the quality, quantity, and marketability of coal reserves within the area served by C&O Railroad. The information gathered was used for the development of coal production from the reserves. Also, he was required to recommend the technical feasibility and economic justification of extending branch lines and/or mine sidetracks for proposed new mines along the system. He assisted in the administration of coal lands owned by C&O Railroad and provided technical sales support for the coal traffic or sales representatives.

Mr. Gaddy was employed in 1953 as a Health and Safety Engineer by the U. S. Bureau of Mines and performed various engineering services and investigations for the Norton, Virginia District. He was a qualified Federal Coal Mine Inspector, but spent most of his time working in the field of roof bolting and mine strata control. In addition, he conducted inquiries of major mine accidents/disasters and did research work in the field of safety.

In 1948, Warner Collieries Company at Mammoth, WV, employed him to perform much of the engineering work for construction of the Emily Mine. During his employment, he performed underground survey services and was foreman on mechanical coal loading sections using 14 RU loading machines, shuttle cars, and "piggyback" chain conveyor equipment.

Mr. Gaddy earned a B.S. Degree in Mining Engineering in 1948 and a M.S. Degree in Mining Engineering in 1956 from Virginia Polytechnic Institute and State University. He is a Registered Professional Engineer (P.E.) in WV, OH, and KY.

His professional memberships include: the Huntington Chapter of the WV Society of Professional Engineers; Professional Engineers in Practice; Society of Professional Engineers (President 1972-1973); National Society of Professional Engineers; Professional Engineers in Private Practice (Vice-Chairman, WVSPE-PEPP 1969-1971); American Institute of Mining, Metallurgical, Petroleum Engineers (Membership Chairman of Central Appalachian Section and National during 1950’s and 1960’s respectively, First Vice-President 1986); American Mining Congress (Chairman of Roof Control Committee 1961-1969); member of WV Coal Mining Institute (President 1975-1976); Sigma Gamma Epsilon (scholastic earth science honorary). He holds First Class Mine Foreman’s Certificates in WV and VA. Furthermore, he is a member of the National Council of Engineering Examiners and is the President of the WV Board of Registration for Professional Engineers.
