NTIS: PB/83-178236 :360 pages
The purpose of this project was to study the constitutive properties of coal under both short- and long-term loadings and to formulate constitutive relations for coal in forms that could be used in stress analysis of underground openings associated with coal mine design. Volume I covers the interrelationship of mechanical, index, and geologic properties of coal measure rock and an executive summary. Volume II presents a study of the orthotropy of coal and other rock materials. Volume III discusses drying shrinkage and creep behavior of coal.
