... to address the particularities of carbonate geologies, including karstic features, layer boundary and through-going fractures, correlations between fracture intensity and bedding thickness. 1 INTRODUCTION The discrete fracture network (DFN) method has been used extensively for carbonate rocks since...

... degrees of cementation the peak strength is closely correlated with the Young’s modulus. There seems to be a strong correlation between porosity and strength. This correlation was further improved by taking into account the primary layering. Sonic travel times also correlate with the peak strength and can...

... ABSTRACT ABSTRACT: A full-scale test stope was excavated at the Carr Fork Mine in the early 1980''s (Pariseau et al. 1984). Correlations between measured displacements in borehole extensometers and two-dimensional finite element model estimates were high, R2 over 0.8. These data were short...

... is often overlooked in calculating rock strength is drilling data. To utilize the drilling data in calculating strength, correlations are developed from inverted rate of penetration models. From these models unconfined compressive rock strength can be calculated from drilling data. The rate of penetration...
