1. Estimating the rock mass deformation modulus: A comparative study of empirical methods based on 48 rock mass scenarios
Abstract The rock mass deformation modulus, Erm, is an input parameter for most numerical modeling to verify the deformation behavior of rocks due to rock engineering activities within/on it. Among the most common methodologies used for estimating this parameter, empirical correlations based on rock mass classification schemes (e.g., RQD, RMR, GSI, and Q) st

2. Geological - geotechnical characterization of different lithotypes in an underground mine
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 a

3. Correlations of rock mass classifications applied to ferruginous caves
Abstract For the Brazilian iron ore mines, the presence of caves presents a challenge, since most of them are located within the ore deposit. The National Environment Commission (CONAMA 347 Resolution/2004) establishes that the speleological heritage, as well as its area of influence, cannot sustain irreversible environmental impacts. The physical integrity

9. EFFECT OF STEEL PLATE THICKNESSES AND FLUID FLOW CHARACTERISTICS OF AN IMPINGING AIR JET ON HEAT TRANSFER AT THE STAGNATION POINT
ABSTRACT The design and process of heat transfer elements, from its source to heat sink through various media vary according to the product and system concerned. The effect of thickness of a steel plate on heat transfer characteristics with an impinging air jet at the stagnation point was studied. Experiments were carried out with different nozzles, heights,

10. Comparison of the Casagrande and Fall Cone Methods for Liquid Limit Determinations in Different Clay Soils
ABSTRACT The liquid limit (LL) is an important parameter for soil classification systems. The use of the cone penetrometer technique for measuring the liquid limit is an attractive alternative method since the percussion method is highly operator dependent. In this article, the importance of specifying the procedure and equipment used to determine the LL of
