NTIS: PB 83-178244 :111 pages
Cores of coal measure rocks from five mines across the United States were tested for mechanical, index, and mineralogic properties. About 600 samples were tested to determine 15 mechanical property parameters, 7 index parameters, and 30 geologic parameters. The results were analyzed for their statistical distributions, and bivariate and multi-variate, linear and nonlinear correlations were attempted for these groups. Significant correlations were found for some of the parameters. On the basis of these statistics, predictive models are postulated for the mechanical properties on the basis of index and geologic parameters.
