Constitutive Relations of Coal and Coal Measure Rocks
The properties of coal from the Pittsburgh seam, procured from the Bruceton and Federal No. 2 mines, were found to be similar. Strength and stiffness properties of Behive mine coal were determined, and the material was found to be isotropic. Mechanical, index, and geologic properties of roof and floor coal measure rocks from Beehive mines were measured and correlated. Analytic formulations are given for coal creep under uniaxial loading, while triaxial creep is being investigated. Results of testing of coal model structures are compared with predictions from using several material models.
