| Popis: | Abstract A mineralogical, geological and geotechnical characterization of several rock types (phyllite, dolomite, breccia and marl) from an underground mine site aimed, among other things, to identify its mineral composition and to provide parameters to support the understanding of rock mass behavior. For this purpose, it was possible to perform laboratory and in situ tests or use existing empirical correlations. In this manuscript, the results of the following laboratory tests are presented and analysed - physical indices, point load test, Schmidt Hammer, uniaxial compression strength, wave propagation, micropetrographic description and X-ray diffraction. It was verified that the results obtained are consistent with other studies carried out in the region and also with results from the technical literature for similar lithotypes. Finally, the results contributed to improve the existing database on correlations among different trials. |
